15th Street–Prospect Park station, History, Service patterns
In July 2009, the G was extended from its long-time terminus at Smith–Ninth Streets to a more efficient terminus at Church Avenue to accommodate the rehabilitation of the Culver Viaduct. The G extension was made permanent in July 2012. In July 2019, the MTA revealed plans to restore express service on the Culver Line between Jay Street and Church Avenue. Express service started on September 16, 2019.


15th Street–Prospect Park station, Station layout
This underground station has two tracks and an island platform. The two express tracks of the line run along a more direct alignment under Prospect Park, and are not visible from this station. The station is approximately 662 feet (202 m) long and 50 feet (15 m) wide, excluding exits and passageways. The station and tunnel were constructed about 100 feet (30 m) east of Prospect Park West. Therefore, the station is not located underneath a street. Some portions of the tunnel are directly underneath Prospect Park, while others are between Prospect Park West and 10th Avenue.


15th Street–Prospect Park station, Station layout
Both trackside walls have an orange-yellow trim line with a medium red-brown border with small black and white "15TH ST" tile captions below it at regular intervals. The tile band is set in a three-high course, a pattern usually reserved for express stations. The tile color was part of a color-coded tile system for the entire Independent Subway System. Ventilation grates are located along the trackside walls. A row of large, white tiled columns runs along either side of the platform and the mezzanine above at 15-foot (4.6 m) intervals. Alternating columns carry the standard black-and-white station name plate. The ceiling of the platform level is held up by H-shaped piers located every 15 feet (4.6 m), which support girders underneath the mezzanine. The roof girders are also connected to columns in the trackside walls.


15th Street–Prospect Park station, Station layout
The tunnel is covered by a "U"-shaped trough that contains utility pipes and wires. The outer walls of this trough are composed of columns, spaced approximately every 5 feet (1.5 m) with concrete infill between them. There is a 1-inch (25 mm) gap between the tunnel wall and the trackside wall, which is made of 4-inch (100 mm)-thick brick covered over by a tiled finish.


15th Street–Prospect Park station, Station layout
The narrow mezzanine is full-length, sparsely decorated with plain tiling typical of the IND, and allows out-of-system walking from one end to the other. Six staircases lead from the platform to the mezzanine. The area inside the fare control area is split into two sections, one considerably smaller than the other.


15th Street–Prospect Park station, Station layout, Exits
There are six entrances to the station in total. The northern end has four exit stairs. Two of them are reached only by a long passageway extending west; one stair goes to the northwest corner of Bartel-Pritchard Square while another goes to the east side of Prospect Park West between 15th Street and Bartel-Pritchard Square. The other two staircases go to the northern and southern sides of Prospect Park Southwest, east of Bartel-Pritchard Square.


15th Street–Prospect Park station, Station layout, Exits
The eastern staircase on Prospect Park West, as well as the northern staircase on Prospect Park South, are located within the boundaries of Prospect Park and contain stone banisters. The other staircases contain metal banisters, typical of other New York City Subway stations. Communications rooms are also located near the Prospect Park West staircase.


15th Street–Prospect Park station, Station layout, Exits
The center of the mezzanine has one staircase going up to the north side of 16th Street while the south end has one staircase going up to the north side of Windsor Place near the intersection of Howard Place. Both stairs contain typical metal banisters. Full height turnstiles provide access to and from the fare control areas near these entrances. The station's only token booth and bank of regular turnstiles is located between the south and center fare control areas, and there are additional communications rooms on the southern end of the mezzanine. Evidence of at least two former booths exist.


15th Street–Prospect Park station, In popular culture
Several dream sequences in the film Pi, which take place in an empty generic-looking New York City Subway station, were shot at 15th Street–Prospect Park.


15th Strike Wing, Philippine Air Force
The 15th Strike Wing is a wing unit of the Philippine Air Force, responsible for overall tactical and ground air support operations in support of Armed Forces of the Philippines units. The unit is headquartered at Danilo Atienza Air Base, Sangley Point, Cavite, just outside the capital Manila. The Wing, as of 2009, was organized with Personal, Coordinating and Technical Staff. Under the Wing's command were units broken up into 3 major groups: Tactical, Maintenance and Supply, and Air Base.


15th Strike Wing, Philippine Air Force
The Wing's tactical elements included the 16th, 17th, 18th, and 20th Attack Squadrons, the 19th Composite Tactical Training Squadron, and the 25th Composite Attack Squadron. Many of these units were forward deployed under the operational control of the Philippine Air Force's numerous Tactical Operations Groups. The 460th Maintenance and Supply Group and the 590th Air Base Group filled the other roles.


15th Strike Wing, Philippine Air Force, History, Beginnings
The 15th Strike Wing was organized and activated as a provisional unit on 26 November 1973, at Sangley Point, Cavite City, with a mission statement: To conduct counter-insurgency and special warfare operations. The appointed Acting Wing Commander then was Colonel Emerito P Surio PAF (GSC), with Colonel Pompeyo P Vasquez PAF (GSC), the Deputy Commander, and a complement of two officers and ten airmen.


15th Strike Wing, Philippine Air Force, History, Beginnings
Initially, the Wing had six (6) Beechcraft T-34 Mentors and six (6) North American T-28 Trojans, mostly from 100th Training Wing and 5th Fighter Wing. Ten (10) airmen were sent to the 410th Air Materiel Wing to undergo maintenance on-the-job training (OJT), in February 1974. Then, additional personnel were reassigned to the Wing such that, by the end of the year, the unit had 27 officers and 288 airmen, who became the nucleus of 15th Strike Wing.


15th Strike Wing, Philippine Air Force, History, Beginnings, 18th Maintenance and Supply Squadron
On 1 July 1974, the 18th Maintenance and Supply Squadron (forerunner of 461st Field Maintenance Squadron), was activated and manned under the leadership of Major Salvador Cereno PAF. A month later, 16th Attack Squadron was organized in anticipation of the delivery of T-28D aircraft from Vietnam. This unit was activated and manned on 1 August 1974, with LT Colonel Santiago O Pitpitan JR PAF as Squadron Commander. Following this, the 17th Attack Squadron was activated on 1 October 1974 and was projected to man the SIAI-FRAT-260 Warriors (SF-260W). However, for several months after the unit's activation, the squadron only manned one (1) T-34A Mentor. The first batch of the Italian-made, locally assembled SF-260W Marchetti aircraft, arrived in late February 1975.


15th Strike Wing, Philippine Air Force, History, Beginnings, 302nd Special Operations Squadron
On 16 October 1974, the  302nd Special Operations Squadron of HPAF was placed under the command and control of the 15th Strike Wing Commander. Two days later, the Wing received the first batch of T-28D aircraft, fresh from the Vietnam War. Trained under Captain Hamilton of the US Air Force and eventually checked out as instructor pilots were: COL Barroga, LT COL PITPITAN JR, LT COL SAMSON, LT COL DAVID and MAJ Billones. These pilots made a smooth transition to the T-28D, bringing forth a new generation of PAF pilots – THE ATTACK PILOTS. Conceptualized mainly to fight insurgency in the country, this new breed of pilots has come to specialize in Close Air Support and Air Interdiction against the enemies of the state.


15th Strike Wing, Philippine Air Force, History, Operational history
On 18 February 1975, after training a handful of Combat-Ready Pilots, the Wing deployed four (4) T-28D aircraft to Edwin Andrews Air Base, Zamboanga City, in support of SOWESCOM operations. Barely three days later, had the first air strike in 15th Strike Wing's history taken place in Kandiis, Province of Basilan.


15th Strike Wing, Philippine Air Force, History, Operational history
On 17 March 1975, three (3) SF-260W aircraft were deployed at the 15th SW Advance Command Post at Francisco Bangoy Airport, Davao City. On 15 April of the same year, the SF-260 Marchettis, piloted by Lt Col Lana and Lt Abaday, wreaked havoc to rebel encampments in Balabagan, Sapakan and Reina Regente, in Central Mindanao.


15th Strike Wing, Philippine Air Force, History, Operational history, 25th Attack Squadron
With the acquisition of additional T-28D aircraft from Udorn AFB in Thailand, another unit, the 25th Attack Squadron, was activated on 29 March 1976. It was given the task to provide Close Air Support to ground and naval forces in the newly organized Western Command, which was then under the concurrent command of the 15th Strike Wing Commander. LT COL TERESO J ISLETA first commanded the 25th Attack Squadron with 71 officers and 36 enlisted personnel. On 13 April of that year, three (3) aircraft of the 15th Strike Wing landed at Puerto Princesa. Following this, they also made a historic landing at Kalayaan.


15th Strike Wing, Philippine Air Force, History, Operational history, Addition of the HU-16 Albatross and Douglas C-47 Skytrain
In May 1976, the Grumman HU-16 Albatross was transferred to 15th Strike Wing from 530th Air Base Group in Zamboanga and was employed as a search and rescue aircraft, thus giving birth to 27th Search, Rescue and Reconnaissance Squadron. Armed with rockets, the Grumann HU-16 Albatross was utilized as Forward Air Controller and SAR aircraft with limited close air support capability. The Wing also had the C-47 Gooney Bird, which was used to ferry personnel, supplies and equipment, and performed other expeditious missions to ensure rapid deployment effectiveness of 15th Strike Wing.


15th Strike Wing, Philippine Air Force, History, Operational history, 1979 Oil Crisis
Towards the end of the 1970s, the oil prices doubled, thus resulting to decrease in flying operations. A crippling shortage of spares was felt in 1979, and a drastic reorganization move was put in place to increase the operational rate of the assigned aircraft. A provisional unit was then established to consolidate all support units. This was the 20th Combat Support Group headed by LT COL NORBERTO P FERRERAS, who was also the wing's chief of maintenance.


15th Strike Wing, Philippine Air Force, History, Operational history, Arrival of helicopters
For the 15th Strike Wing, the 1980s also ushered in major changes. In anticipation of the AUH-76's arrival, the 20th Air Commando Squadron was activated on 1 October 1983. In 1984, President Ferdinand Marcos facilitated the acquisition of Sikorsky AUH-76 helicopters, which the Philippine Air Force configured as a platform for rockets and machine guns, from its original design as a VIP passenger aircraft. Two (2) S-70A Blackhawks also arrived together with the three AUH-76.


15th Strike Wing, Philippine Air Force, History, Operational history, Arrival of helicopters
Two of the AUH-76 helicopters were configured as rescue helicopters, thus placing the 505th Air Rescue Squadron of the 205th Helicopter Wing under 15th Strike Wing control, on 1 April 1984. As an attack helicopter, the AUH-76 saw action not only in Mindanao but also in the Visayas and Northern Luzon as well.


15th Strike Wing, Philippine Air Force, History, Operational history, Arrival of helicopters
Preceding the arrival of the AUH-76 was the transfer of the SF-260s, during the early part of 1983, to 100th Training Wing. Consequently, the 25th Attack Squadron was unmanned on 1 October 1983.


15th Strike Wing, Philippine Air Force, History, Political and financial tensions
With the political tension that pervaded the country after the assassination of Benigno Aquino Jr., economic instability spelled budgetary cuts for the government. Maintenance cost increased while some pilots opted to leave the service to seek for “greener pastures.” Because of this drain in personnel and equipment, the 17th Attack Squadron was unmanned on 1 August 1985, leaving the 16th Attack Squadron as the only tactical squadron under 15th Strike Wing.


15th Strike Wing, Philippine Air Force, History, Political and financial tensions, 1986 EDSA 'People Power' Revolution
The finest hour of the 15th Strike Wing came during the 1986 EDSA People Power Revolution. The Wing Commander, then COLONEL ANTONIO E SOTELO, led a flight of Sikorsky gun ships to join forces with rebel forces at Camp Crame. The “Sotelo Landing” tilted the balance in favor of the Enrile-Ramos faction and inspired other military commanders as well. This eventually led to the end of the 20-year Marcos Regime. Following this, Corazon Aquino, the widow of Benigno Aquino Jr., assumed as President of the Republic. Consequently, the military enjoyed renewed respect and confidence from the populace.


15th Strike Wing, Philippine Air Force, History, Political and financial tensions, 1986–1987 Coup Attempts
Between 1986 and 1987 several coup d’etats were launched against the Aquino Administration.


15th Strike Wing, Philippine Air Force, History, Political and financial tensions, 1986–1987 Coup Attempts
In January 1987, Marcos loyalists simultaneously held a so-called “Military Exercise” at Villamor Air Base and Sangley Air Base. Several officers of the Wing were held at gunpoint at the Wing Operations Center, some were held hostage elsewhere. The coup attempt failed, before the day's end command and control of the Wing was restored.


15th Strike Wing, Philippine Air Force, History, Political and financial tensions, 1986–1987 Coup Attempts
On 28 August 1987, another attempt to overthrow the Aquino Government was mounted. Again, 15th Strike Wing stood its ground to protect our national interests and integrity. At the height of the tension, at the time when rebel forces had control over TV 13 and GHQ building, two T-28Ds took off from Sangley Point and proceeded to Balara Relay Station and released deadly warnings at the vicinity of the area occupied by rebel soldiers. Then, later in the afternoon, the Tora-Toras struck with precision identified targets at Camp Aguinaldo. These events eventually led the rebels to raise the white flag, thus ending the coup attempt.


15th Strike Wing, Philippine Air Force, History, Political and financial tensions, 1986–1987 Coup Attempts
In December 1989, 15th Strike Wing was one of the focal points of another coup attempt, which turned out to be the bloodiest. On 30 November 1989, coup plotters began occupying the Sangley Air Base, which was considered as their ace. By midnight, all aircraft were already under the control of the rebel soldiers. Other base facilities and vital installations also fell into their hands. By early morning of December 1, rebel pilots were already set to launch air strikes. In the first seven days of December, T-28Ds piloted by rebel pilots strafed Malacañang Palace grounds; they were in control of the skies.


15th Strike Wing, Philippine Air Force, History, Political and financial tensions, 1986–1987 Coup Attempts
With Sangley Air Base under their control, the rebels had the upper hand. The government, on the other hand, realized the implications of this situation; so, 5th Fighter Wing was tasked to conduct persuasion flights. By the following morning, a flight of F-5 Freedom Fighters led by Major Danilo Atienza, conducted a persuasion flight over Sangley Air Base. But because the rebels were firm on holding their ground, the F-5 pilots were later directed to retake Sangley at all costs. And so air strikes were conducted, inflicting heavy damage on aircraft and facilities controlled by the enemy.


15th Strike Wing, Philippine Air Force, History, Political and financial tensions, 1986–1987 Coup Attempts
Unfortunately, Major Atienza crashed after flames from the explosion of a fuel depot engulfed his F-5, killing him in the process. More than two years later, on 5 May 1992, the airfield of Sangley was renamed Major Danilo S Atienza Airfield pursuant to Republic Act 7429 in recognition of his gallantry and intrepidity.


15th Strike Wing, Philippine Air Force, History, Merger of 240th Composite Wing and 15th Strike Wing
The most drastic change in Sangley was the merging of the 240th Composite Wing and the 15th Strike Wing, in 1987. The 240th Composite Wing was unmanned on 16 January 1987; subsequently, on 24 February 1987, Sangley Air Base was recognized as a single-wing base. 15th Strike Wing then absorbed 240th CW and, from then on, functioned both as a tactical unit and as a base keeper of Sangley Air Base. Due to the increase in manpower and equipment that was brought upon by the merging of the two units, the 505th Air Rescue Squadron was transferred to the 205th Helicopter Wing on 16 July 1987.


15th Strike Wing, Philippine Air Force, History, Merger of 240th Composite Wing and 15th Strike Wing
Changes occurred in 15th Strike Wing even towards the end of the decade. On 15 July 1990, 17th Air Commando Squadron and the 25th Air Commando Training Squadron were re-manned. The 601st Liaison Squadron, the only squadron from the 240th CW to have survived the merger with 15th SW, was unmanned on the same date.


15th Strike Wing, Philippine Air Force, History, Reactivation of the 17th Attack Squadron
Another significant development in the 15th Strike Wing was the reactivation of the 17th Attack Squadron. It was deactivated in March 1998 due to dwindling air assets.


15th Strike Wing, Philippine Air Force, History, Reactivation of the 17th Attack Squadron
The 17th Attack Squadron was reactivated on July 16, 2001. This time with a fleet of reconfigured SF-260TPs. On November 27, 2001, a few months after the squadron's reactivation, the 17th AS conducted several missions against the secessionist Misuari Renegade Group in Zamboanga City.


15th Strike Wing, Philippine Air Force, History, Reactivation of the 25th Composite Attack Squadron
Lt . Gen. Jose L. Reyes, during his term as Wing Commander of the 15th Strike Wing, thought of reactivating the 25th Composite Attack Squadron. On July 19, 2004, the 25th Attack Squadron or “LOBOS”, was reactivated and is based at Edwin Andrews Air Base, Zamboanga City. This unit will manage, operate and maintain the Wing's assets in Mindanao such as the OV-10 Bronco, MD-520 MG and SF-260 TP aircraft. Thirty-four (34) able officers and enlisted personnel composed the reactivated 25th CAS.


15th Strike Wing, Philippine Air Force, Organization
The Wing is organized in the line and staff structure with Personal, Coordinating and Technical Staff. Under the Command and control of the Wing Commander are three (3) Major Groups. Namely; Tactical Group, Maintenance and Supply Group and Air Base Group.


15th Sustainment Brigade
The 15th Sustainment Brigade was a sustainment brigade of the United States Army based at Fort Bliss, Texas. It provided logistics support to other units of the United States Army, and was subordinate to the 13th Sustainment Command (Expeditionary). It previously had provided support to the 1st Cavalry Division, but now did so for the 1st Armored Division until 12 May 2015 when the 15th Sustainment Brigade became part of the 1st Armored Division and was renamed 1st Armored Division Sustainment Brigade.


15th Sustainment Brigade
The brigade's lineage dates back to 1919, and it had a long and decorated history when designated as the supply command of the 1st Cavalry Division. Having seen service in every major conflict of the 20th century in support of its parent division, the unit was not designated as the 15th Sustainment Brigade permanently until 2005. In February 2008, the brigade was reassigned to the 13th Sustainment Command (Expeditionary), ending almost a century of association with the 1st Cavalry Division.


15th Sustainment Brigade
The 15th Sustainment Brigade's extensive lineage also carries many honors for the unit. What is now the 15th Sustainment Brigade, and its previous incarnations, have earned 17 campaign streamers, as well as numerous awards, mostly for service during the Vietnam War. These decorations include the Presidential Unit Citation, the Valorous Unit Award, and five Meritorious Unit Commendations.


15th Sustainment Brigade, Organization
The 15th Sustainment Brigade was permanently attached to the 1st Cavalry Division, though it could operate independently when needed. Currently, it falls under the organization of the 1st Armored Division, having relocated as part of the Base Realignment and Closure 2005. This assignment allows the unit maximum flexibility when deployed, as it can provide any support function needed, without being permanently attached to any particular unit or area of operations.


15th Sustainment Brigade, Organization
The unit has two permanently assigned battalions along with its Headquarters and Headquarters Company (HHC). They consist of the 15th Special Troops Battalion, and the 142nd Combat Sustainment Support Battalion which are also headquartered at Fort Bliss, Texas. 72nd Brigade Support Battalion inactivated in November 2014, in conjunction with inactivation of 212th Fires Brigade (United States) in July 2014.


15th Sustainment Brigade, Organization
In addition, Company A, 125th Brigade Support Battalion (formerly with 3rd BCT), in conjunction with the inactivation of 3rd BCT, completed a high-visibility project: Company A produced the first Redistribution Property Accountability Team  (RPAT) yard in the continental US, which gives commanders a clear picture of property redistribution, especially during a unit's closure. The brigade command is modular in design, allowing it to assume command of additional units when deployed. The command is preparing for deployment to Southwest Asia in 2015.


15th Sustainment Brigade, History, Origins
The 15th Sustainment Brigade was originally constituted on 4 May 1966 in the Regular Army as a Headquarters and Headquarters Company. It was first activated on 1 July 1966.


15th Sustainment Brigade, History, Origins
On 20 October 1967, the Brigade was inactivated after providing support to units in Vietnam, only to be reactivated on 21 September 1968 at Fort Lewis, Washington. The Brigade later inactivated at Fort Lewis on 21 March 1973 having received campaign credits for its support for Counteroffensive Operations (Phase II and III) in Vietnam.


15th Sustainment Brigade, History, Origins
As mentioned above, the 15th Sustainment Brigade replaced the "Division Support Command" of the 1st Cavalry Division. The history of the organization can be traced back to 1919 when one of its present units, the 15th Forward Support Battalion, existed as the 615th Motor Transport Company. The Division Support Command (DISCOM) thus predated the 1st Cavalry Division itself, which was not established until 1921.


15th Sustainment Brigade, History, Origins
In the years before World War II, most of the units of the 1st Cavalry Division that were not assigned to larger unit commands were under the control of the Headquarters, Division Special Troops of the division; an independent unit for various supporting units for a division. These included the service and support elements of the division. After World War II, however, the Special Troops Headquarters was reorganized into Headquarters, Division Trains. This designation immediately predates the "Division Support Command" (DISCOM) designation. The division trains were activated 1 November 1957 in Korea. Although a new organization, 1st Cavalry Division's Division Trains employed concepts and tactics similar to those of U.S. armored division trains that were originated in World War I.


15th Sustainment Brigade, History, Vietnam War
On 1 September 1963, Headquarters, Division Trains was reorganized under the "R.O.A.D." (Reorganization of the Army Divisions) plan and redesignated as Headquarters, Headquarters Company and Band, 1st Cavalry Division, 1st Cavalry Division Support Command. Accompanying the division to Vietnam in August 1965, the Support Command participated in all of the same campaigns that the division did, providing logistics support for the 1st Cavalry Division throughout the entire conflict.


15th Sustainment Brigade, History, Vietnam War
The unit's first major operation was the Pleiku Campaign. During this action, the command supported the division during 35 days of continuous airmobile operations. The opening battle of the campaign, the Battle of Ia Drang Valley, was described in the book We Were Soldiers Once... And Young which was also the basis of the subsequent Mel Gibson film We Were Soldiers.


15th Sustainment Brigade, History, Vietnam War
For most of 1967 and early 1968, the formation supported the 1st Cavalry Division through Operation Pershing. This was a large scale search of areas under the jurisdiction of the US II Corps which, according to the US Army, saw 5,400 enemy killed and 2,000 captured. The division re-deployed to Camp Evans, north of Hue in the I Corps Tactical Zone, during the 1968 Tet Offensive It was involved in recapturing Quang Tri and Hue regions.


15th Sustainment Brigade, History, Vietnam War
After intense fighting in Hue, the division then moved to relieve US Marine Corps units besieged at the Khe Sanh combat base in Operation Pegasus through March 1968. The 1st Cavalry Division next conducted major clearing operations in the Ashau Valley from mid-April through mid-May 1968. From May until September 1968, the division participated in local pacification missions, as well as Medical outreach programs intended to offer medical support to the Vietnamese local population. During this time, the division and support command were assigned to I Corps.


15th Sustainment Brigade, History, Vietnam War
In the autumn of 1968, the 1st Cavalry Division relocated south to the III Corps Tactical Zone northwest of Saigon, adjacent to a Cambodian region commonly referred to as the "Parrots Beak", due to its shape. In May 1970, the division was among U.S. units participating in the Cambodian Incursion, withdrawing from Cambodia on 29 June. The division thereafter took a defensive posture while the withdrawal of U.S. troops from Vietnam continued. The bulk of the division was withdrawn on 29 April 1971.


15th Sustainment Brigade, History, Vietnam War
The Division Support Command received all of the same honors as the division headquarters throughout the conflict. These awards included the Presidential Unit Citation for the actions in Pleiku Province and the Valorous Unit Award for action in the "Parrots Beak" area of Cambodia (referred to as the "Fish Hook" area in the unit's award streamer). In addition, Support Command received three Meritorious Unit Commendations and four Republic of Vietnam Cross of Gallantry awards throughout the deployments.


15th Sustainment Brigade, History, Vietnam War
On 15 May 1971, the DISCOM was reorganized and designated as Headquarters and Headquarters Company, 1st Cavalry Division Support Command. Most major subordinate units of the DISCOM had returned from Vietnam in 1971 and were stationed at Fort Hood. By the end of June 1971, the DISCOM was a large command composed of HHC, Support Command, 15th Adjutant General Company/Band, 15th Medical Battalion, 15th Supply and Transport Battalion, 27th Maintenance Battalion, 8th Engineer Battalion, 315th Composite Support Battalion, 15th Finance Company (the latter two units had been transferred from the 1st Armored Division), and the 15th Data Processing Unit.


15th Sustainment Brigade, History, Reorganizations & The Gulf War
During the early 1980s, the DISCOM consisted of a Headquarters Company, a Division Materiel Management Center, a Division Data Center, the 15th Medical Battalion, 15th Adjutant General Battalion, 15th Finance Company, 15th Supply and Transport Battalion, 27th Maintenance Battalion and the 68th Chemical Company. In October 1984, the 1st and 2nd Forward Support Battalions were activated from elements of the three functional battalions attached to the unit. The following year saw the Army of Excellence Reorganization (AOE) transform the remaining elements of the three functional battalions (maintenance, medical, and supply and transport) into the 4th Main Support Battalion. The AOE reorganization also added the 493rd Transportation Company (Aircraft Maintenance) to the Division Support Command. The forward and main support battalions, along with the Aviation Maintenance Company, were redesignated in 1987, becoming the 15th and 115th Forward Support Battalions, 27th Main Support Battalion, and 227th Transportation Company (Aviation Maintenance).


15th Sustainment Brigade, History, Reorganizations & The Gulf War
On 28 September 1990, the Division Support Command deployed to the Middle East in support of Operation Desert Shield. In January 1991, Division Support Command provided support to the 1st Cavalry Division throughout Operation Desert Storm, leading to a quick liberation of Kuwait. On 16 December 1991, the 215th Forward Support Battalion was activated at Fort Hood bringing the number of active duty forward support battalions to three. On 8 July 1996, the 615th Support Battalion (Aviation) was provisionally organized. The battalion was formally activated on 17 September 1996.


15th Sustainment Brigade, History, Activation & Operation Iraqi Freedom
On 6 July 2005, the Division Support Command (DISCOM) of the 1st Cavalry Division was inactivated and redesignated the 15th Sustainment Brigade. DISCOM’s previously subordinate Forward Support Battalions were redesignated Brigade Support Battalions and task organized under their supported maneuver brigade.


15th Sustainment Brigade, History, Activation & Operation Iraqi Freedom
The 15th Sustainment Brigade was the first element of the 1st Cavalry Division to return to Iraq and assumed control for logistics in the Baghdad area of operations in July 2006. The Brigade provided command and control for numerous units not normally associated with the 1st Cavalry Division. It had sustained several casualties during its tour in the country, including a mortar attack that killed two soldiers and injured five more in October 2007. Tasks the unit completed during its 2006–2007 tour in Iraq included construction and maintenance of sustainment facilities, and maintaining vehicles, including adding additional armor to Humvee vehicles for other US units operating in the country.


15th Sustainment Brigade, History, Activation & Operation Iraqi Freedom
The Brigade changed its higher command for the first time in its history on 15 February 2008. It was reassigned from the 1st Cavalry Division to the 13th Sustainment Command (Expeditionary), holding a mock cavalry charge to celebrate the occasion. This would also mark the first time that the brigade served independently from the 1st Cavalry Division. Since returning from Iraq, the brigade has undertaken a number of duties around Fort Hood. These activities include testing new systems for use during deployments, remodeling infrastructure around the fort, and training on personal safety.


15th Sustainment Brigade, Legacy
The Sustainment Brigade and its soldiers have been the subject of numerous army publications during its tours in Iraq, most of which having to do with the culture and lifestyle of soldiers serving the unit. Among these have been feature stories by the Multi-National Force: Iraq public affairs office, on married soldiers who deploy together. The Army Logistician, an Army publication for soldiers serving in support units, published a feature story on the stories of soldiers serving in Iraq for their September–October 2007 issue. This story was intended to display the versatility of sustainment brigades overall. Another story was written for defenselink.mil, the press service for the United States Armed Forces in March 2007 about soldiers of the brigade and how they react to the desert climate of the country, having to cope with sandstorms and other issues.

15th Tank Corps
The 15th Tank Corps (Russian: 15-й танковый корпус, 15-y tankoviy korpus) was a tank corps of the Soviet Union's Red Army. It formed in 1938 from a mechanized corps and fought in the Soviet invasion of Poland, during which it participated in the capture of the Grodno and Augustów Forest from Poland. The corps was disbanded in January 1940 at  Wilno and Soleczniki.


15th Tank Corps
In 1942, the corps was reformed under the command of Major General Vasily Koptsov and became part of the 3rd Tank Army. It first saw combat in the unsuccessful Kozelsk Offensive of late August and early September, a relatively small operation to encircle a German salient, which resulted in the corps taking heavy losses in proportion to the territory gained.


15th Tank Corps
After spending the rest of the year in reserve, receiving new supplies and equipment, the corps was transferred to the southern front in southwestern Russia to fight in the Ostrogozhsk–Rossosh Offensive during January 1943, in which it played a major role by forming part of the forces that encircled thousands of Axis troops on the middle reaches of the Don River.


15th Tank Corps
In February 1943, the unit fought in Operation Star, achieving its objective of recapturing the key city of Kharkov in eastern Ukraine. As the Soviet advance outran its supply lines, the corps was slowly worn down and was virtually destroyed after being surrounded by a German counteroffensive in the Third Battle of Kharkov during late February and early March. Koptsov was among those killed in the fighting. The corps was rebuilt in the following months and became part of the newly created 3rd Guards Tank Army, fighting in Operation Kutuzov, the Soviet counteroffensive during the Battle of Kursk, in late July. For its actions in the offensive, the corps was converted into the 7th Guards Tank Corps.


15th Tank Corps, First formation
The 15th Tank Corps formed in 1938 from the 5th Mechanized Corps at Naro-Fominsk in the Moscow Military District, inheriting the honorific "named for (Konstantin) Kalinovsky", a Soviet military theorist. Commanded by Komdiv (equivalent to Lieutenant General) Mikhail Petrovich Petrov, the corps included the 2nd Light Tank Brigade (previously the 5th Mechanized Brigade), the 27th Light Tank Brigade (formerly 10th Mechanized Brigade), the 20th Motor Rifle and Machine Gun Brigade (formerly 50th Rifle and Machine Gun Brigade), and the 401st Separate Communications Battalion, a support unit.


15th Tank Corps, First formation
Soon after its formation, the corps was transferred to the Belorussian Special Military District, its headquarters located in Borisov. The 2nd and 27th Light Tank Brigades were based in Borisov, and the 20th Motor Rifle and Machine Gun Brigade was based in Mogilev. The 89th Separate Air Liaison Flight formed as part of the corps at Borisov on 4 August, operating Polikarpov R-5 and U-2 biplanes.


15th Tank Corps, First formation, Soviet invasion of Poland, Initial advance
The corps fought in the Soviet invasion of Poland in September 1939, as part of Ivan Boldin's Dzerzhinsky Cavalry-Mechanized Group (KMG). The invasion was conducted under the terms of the Molotov–Ribbentrop Pact, which divided Poland between the Soviet Union and Nazi Germany and guaranteed that neither country would attack the other. At the beginning of the campaign, the 2nd Brigade had 234 BT-7 light tanks and 30 BA armored cars, the 27th Brigade had 223 BT-7s and 31 BAs, and the 20th Brigade had 61 BAs; the corps thus fielded 461 tanks and 122 armored cars.


15th Tank Corps, First formation, Soviet invasion of Poland, Initial advance
On 17 September, at 05:00, the corps, advancing on the KMG's southern flank, crossed the state border, overran the Polish border guards, and began a rapid advance without resistance; most of the Polish troops in the east had been transferred west to fight against the German invasion of Poland earlier in the month. By 12:00, the 27th Brigade had reached Mir and Ajucavičy, overrunning the practically undefended Nowosiółki–Kajszówki sector of the Baranovichi Fortified Region.


15th Tank Corps, First formation, Soviet invasion of Poland, Initial advance
By the end of the day, the 27th Brigade had crossed the Servach River in the Lubanichi area, the 2nd Brigade had crossed the Usza River, and the 20th Brigade had advanced to the border at Losha. During the day, the corps suffered casualties of one killed and two wounded. On 18 September, the 27th Brigade advanced from the line of Rudašy and Zaberdowo, but was bogged down for several hours while moving through the area near Golewicze.


15th Tank Corps, First formation, Soviet invasion of Poland, Initial advance
As a result, it did not reach the Jarniewo area, 2 kilometers (1.2 mi) west of Slonim, until the morning of 19 September. After the retreating Polish garrison burned one of the two bridges over the Shchara River, the 2nd Brigade entered Slonim and disarmed 80 policemen. On 19 September, the brigade reached Vawkavysk, and the corps was ordered to take Grodno and Sokółka by the end of the day, in conjunction with the motorcycle units of the 4th and 13th Rifle Divisions. At the same time the 27th Brigade captured Dvorets, disarming 400 people and capturing 300 rifles, but fuel shortages kept the corps stretched out along the Slonim–Vawkavysk road awaiting refueling. The 20th Brigade approached Slonim from the east, further clogging the roads and delaying the arrival of supply units.


15th Tank Corps, First formation, Soviet invasion of Poland, Battle of Grodno
After receiving fuel from 07:00 on 20 September, the units of the corps began to advance on Grodno in multiple waves. At 13:00, 50 tanks from the 27th Brigade reached the southern outskirts of the city, beginning the Battle of Grodno. By 14:00, the 2nd Brigade had taken Sokółka, and its advance units had reached Dąbrowa. At the end of the day, motorcycle units of the 4th Rifle Division and battalions of the 20th Motor Rifle and Machine Gun Brigade, which had all been delayed by fuel shortages, had reached the city.


15th Tank Corps, First formation, Soviet invasion of Poland, Battle of Grodno
Grodno was defended by an understrength force of up to 3,000 Polish officers, gendarmes, and volunteers who had burned the bridges across the Neman. The 27th Brigade's reconnaissance battalion launched the first attack with 12 tanks and an armored car, and was later joined by two tank battalions with a total of 36 tanks.


15th Tank Corps, First formation, Soviet invasion of Poland, Battle of Grodno
By 19:00, two battalions of the 13th Rifle Division's 119th Rifle Regiment had arrived at Grodno, and on the morning of 21 September they were reinforced by two battalions of the 4th Rifle Division's 101st Rifle Regiment and the motorized detachment of the 16th Rifle Corps, the latter of which was subordinated to the corps for the duration of the battle. By the end of 20 September, the combined forces had captured the southern part of Grodno.


15th Tank Corps, First formation, Soviet invasion of Poland, Battle of Grodno
At 07:00 on 21 September, the artillery batteries of the two rifle regiments and the 20th Brigade commenced firing from the southern bank of the Niemen, demolishing the main Polish strongpoints—barracks, churches, and trenches—on the northern bank of the Niemen. The 119th Regiment then crossed to the north bank and rebuilt a bridge for the tanks to use. After defeating a group of Polish officers in the Poniemuń district, the regiment captured the eastern part of the city.


15th Tank Corps, First formation, Soviet invasion of Poland, Battle of Grodno
Meanwhile, the 101st Regiment and a tank company from the 27th Brigade, which crossed the river behind the 119th, destroyed a group of about 250 officers defending the wooded hills 1.5 kilometers (0.93 mi) east of the city, then advanced northeast and captured the railway station by the end of the day. The 20th Brigade captured the southwestern part of the city, but was unable to advance northward because of strong Polish resistance in the houses and trenches near the bridge and the tobacco factory. The Soviet advances on 21 September resulted in the suppression of large pockets of resistance, and during the night, remnants of the Polish defenders retreated in the direction of Sapotskin and Suwałki.


15th Tank Corps, First formation, Soviet invasion of Poland, Battle of Grodno
Grodno was cleared of Polish troops on 22 September. The 27th Brigade lost two burned and 12 damaged BT-7 light tanks in the battle, some to Molotov cocktails thrown by the defenders from attics and trenches, and its casualties totaled 19 killed and 26 wounded. The 20th Brigade lost a BA-10 to Molotov cocktails, suffering casualties of 3 killed and 20 wounded. The 16th Rifle Corps' motorized detachment lost 25 killed, 110 wounded, and a burned tank.


15th Tank Corps, First formation, Soviet invasion of Poland, Battle of Grodno
During the battle, the corps killed 320 officers, 20 non-commissioned officers, and 194 soldiers, many of whom were crushed by tanks in the eastern part of the city. Between 20 and 21 September, they had captured 38 Polish officers, 20 non-commissioned officers, and 1,477 enlisted men, as well as 514 rifles, 146 machine guns, a mortar, and an anti-aircraft gun.


15th Tank Corps, First formation, Soviet invasion of Poland, Mopping up operations and disbandment
One detachment from the 2nd Brigade, under the command of Major F.P. Chuvakin, was composed of a machine gun and rifle battalion and 45 tanks, 37 of which were from the brigade and the rest from the KMG. It was attached to the KMG to mop up remaining resistance in the Augustów Forest and to prevent the Poles fleeing to Lithuania. On 22 September, in the area of Sapotskin, the detachment engaged units of the Polish 101st and 102nd Uhlan Regiments, as well as the 110th Reserve Uhlan Regiment, and other units retreating from Grodno.


15th Tank Corps, First formation, Soviet invasion of Poland, Mopping up operations and disbandment
Most of the Polish troops escaped into the forest because of the slow advance of the detachment. Around three companies of Polish troops were dispersed and several officers were killed, among them the Grodno defense commander, Józef Olszyna-Wilczyński. The retreating Polish forces left mines, which blew up four BT-7 tanks. Chuvakin's troops also lost 11 killed and 14 wounded.


15th Tank Corps, First formation, Soviet invasion of Poland, Mopping up operations and disbandment
The detachment advanced to Sejny and on 23 September reached the Augustów Canal at Vulka, where it was stopped by Polish troops on the left bank, who had burned the bridge over the canal. A tank company forded the canal and forced the defenders to retreat, leaving nine dead. In the fighting of 22 and 23 September, the detachment killed about 40 officers and many soldiers, and captured more than 500 troops, 300 rifles, and 12 machine guns. On 23 September, the 20th Brigade moved to Dąbrowa, where it eliminated remnants of Polish units in the Augustów Forest.


15th Tank Corps, First formation, Soviet invasion of Poland, Mopping up operations and disbandment
Two days later, 15 armored cars were detached from the brigade to relieve German troops garrisoning the Osowiec Fortress, which fell in the Soviet sphere of influence under the Molotov–Ribbentrop Pact. Between 23 and 26 September, a detachment of 20 tanks and armored cars from the 27th Brigade and a rifle battalion moved along the road from Grodno to Augustów, and back again, capturing 300 prisoners along the way. During the campaign, the corps killed 78 officers, 133 non-commissioned officers, and 2,337 soldiers. It captured 322 officers, 30 non-commissioned officers, and 352 soldiers, as well as 814 rifles, 153 machine guns, a mortar, two cannons, and 15 cars.


15th Tank Corps, First formation, Soviet invasion of Poland, Mopping up operations and disbandment
By 2 October, the KMG was disbanded and the corps was subordinated to the 3rd Army. On 10 October, the corps headquarters and the tank brigades were stationed at Wilno, and the 20th Brigade was at Soleczniki. The 15th was disbanded along with the other tank corps in January 1940; the Main Military Council considered the tank corps' performance in Poland unsatisfactory, believing them to be unwieldy and difficult to control.


15th Tank Corps, Second formation
The corps was re-formed in May 1942 at the Moscow Armored Training Center, nearly a year after Germany had abandoned the Molotov–Ribbentrop Pact and invaded the Soviet Union. Major General Vasily Koptsov took command of the formation, which included the 96th and 113th Tank Brigades, the 105th Heavy Tank Brigade, the 17th Motor Rifle Brigade, and the 5th Reconnaissance Battalion. The corps was assigned to the 3rd Tank Army on 25 May, and as of 2 June included 150 tanks, comprising 30 KV tanks, 60 T-34 tanks, and 60 T-60 light tanks.


15th Tank Corps, Second formation
The corps concentrated in the Tula area with the rest of the army, conducting intensive training exercises. After Axis forces launched the Case Blue summer offensive in southern Russia in late June, Stavka believed that an attack by Army Group Centre on the Oryol axis was possible, and ordered the army to concentrate in the Yefremov area. On 6 July, the army was ordered to concentrate to the west in the Chern area, moving closer to the front.


15th Tank Corps, Second formation
The relocation was completed by 9 July, and the 15th Tank Corps was positioned in the area of the Agnichnoye State Farm, Dupny, Bolshoy Kon, Gremyachevo, Yasnyy Lug, and Korotky, where it engaged in combat training and created a defensive line in readiness to repulse a German attack. Late that month, the 96th Brigade was transferred to the Bryansk Front, and it was replaced by the 195th Tank Brigade between 10 and 12 August.


15th Tank Corps, Second formation, Kozelsk Offensive
In early August, the 2nd Panzer Army launched a limited offensive towards Sukhinichi in an attempt to eliminate a Soviet salient. The attack was initially successful, but soon bogged down in the face of determined Soviet resistance. To eliminate the penetration and encircle the lead forces of the 2nd Panzer Army, the Kozelsk Offensive was launched by the 3rd Tank Army on the eastern flank of the salient. On 14 August, the order was given to relocate to the Kozelsk area in preparation for the attack; the army began moving the following night, the tanks being transported by rail.


15th Tank Corps, Second formation, Kozelsk Offensive
The offensive was scheduled to begin on 19 August, but was postponed to 22 August after rains turned the roads to mud, delaying the arrival of the motorized infantry and vehicles from the morning of 16 August to late on 17 August. Railway logistical difficulties resulted in the transfer of personnel and equipment being completed only on 21 August, and cargo only by the end of 24 August. Soviet preparations for the attack were detected by German intelligence, and the German troops in the salient were reinforced and began preparing strong defensive lines. At the beginning of the offensive, the corps was at full strength, with 24 KV tanks, 87 T-34s, and 48 T-60 and 21 T-70 light tanks, a total of 180 tanks.


15th Tank Corps, Second formation, Kozelsk Offensive
For the attack, Koptsov was placed in command of a group consisting of the 15th Tank Corps and the 154th Rifle Division, reinforced by support units. The group's immediate objective was to advance towards Meshalkino, Myzin, Marino, and Belyi Verkh, then cross the Vytebet River and establish a bridgehead on its west bank. It was afterwards to surround and destroy German troops in the area of Trostyapka, Perestryazh, and Belyi Verkh, operating in conjunction with the 16th and the 61st Armies.


15th Tank Corps, Second formation, Kozelsk Offensive
On the first day of the attack, the 154th and 264th Rifle Divisions were sent into the attack first, but could not break through. The 12th Tank Corps was committed to the fight, but came under heavy German air attack and was stopped. At 12:00, a report was received that the 3rd Tank Corps had seized Smetskiye Vyselkami and advanced westwards. Considering that the main advance was halted by German resistance, Western Front commander Georgy Zhukov ordered the relocation of the 15th Tank Corps to that sector.


15th Tank Corps, Second formation, Kozelsk Offensive
The corps was to advance towards Slobodka and Belyi Verkh, but the report of Smetskiye Vyselkami's capture proved to be false, and the 15th's vanguard suffered heavy losses approaching the village. The 105th Heavy Tank Brigade and 17th Motor Rifle Brigade captured Smetskiye Vyselkami from the 56th Infantry Division's 192nd Infantry Regiment in fierce fighting by 17:00, but the corps was unable to make a breakthrough, becoming delayed by difficulties in traversing swampy terrain, getting lost while moving through forest trails, and running into minefields.


15th Tank Corps, Second formation, Kozelsk Offensive
The delays in the advance caused the armor to lag behind the infantry, and the tank columns came under heavy German air attack before reaching the fight on 23 August. For the next two days, the corps advanced slowly alongside other units, overcoming stubborn German resistance, before finally clearing the forests east of the Vytebet River of German troops on 25 August. The corps was unable to cross the river due to the firm German defenses on the other side.


15th Tank Corps, Second formation, Kozelsk Offensive
The next day, to end German resistance on the left flank, where the attacks of the 12th Tank Corps and 154th Rifle Division were unsuccessful, the corps was ordered to withdraw from the front in the Zhukovo area and reconcentrate in the forest 3 kilometers (1.9 mi) west of Myzin. It was then to capture Sorokino in conjunction with the 12th Tank Corps and 154th Rifle Division. After moving 15 kilometers (9.3 mi) to its new starting positions, the corps attacked at dawn on 26 August, but was again stymied by the forest terrain.


15th Tank Corps, Second formation, Kozelsk Offensive
The same day, the 12th Tank Corps and 264th Rifle Division came under heavy pressure from German tank counterattacks. On 27 August, army commander Prokofy Romanenko, fearing a breakthrough from the south, ordered the 15th Corps to concentrate in the forests north of Novogryn, in readiness to counterattack if a German breakthrough took place. In the event, by the end of the day, the Soviet lines had held and the 15th was not needed in that sector.


15th Tank Corps, Second formation, Kozelsk Offensive
That night, it was relocated from the Myzin area to the Pakom area, where, together with the 61st Army's 12th Guards Rifle Division, it was to break German resistance near Leonovo, then develop the breakthrough towards Ukolitsa into the rear of the German troops defending against the 154th and 264th Rifle Divisions and the 12th Corps at Bogdanovsky and Goskovo. On the afternoon of 28 August, the corps attacked after a 30-minute artillery bombardment and airstrikes, but was immediately stalled by an anti-tank ditch protected by minefields and artillery.


15th Tank Corps, Second formation, Kozelsk Offensive
During the night, sappers and motorized infantry managed to create passages through the ditch, but when the offensive was resumed the next morning, the 15th had advanced only 200–300 meters (660–980 ft) before it was stopped by a second anti-tank ditch. It tried to break through during the day, but could not cross the ditch.


15th Tank Corps, Second formation, Kozelsk Offensive
On the night of 29/30 August, the corps was pulled out of the line and concentrated in the forest a kilometer south of Meshalkino to carry out an attack on Sorokino in conjunction with the 154th Rifle Division and 12th Tank Corps. The attack was cancelled due to the heavy losses suffered by both the 12th Tank Corps and 154th Rifle Division in the previous fighting, and the 15th also required time to reorganize.


15th Tank Corps, Second formation, Kozelsk Offensive
During the day the corps' 195th Tank Brigade conducted the only combat action, a successful operation to relieve two encircled battalions of the 61st Army's 156th Rifle Division. While the main forces of the 3rd Tank Army had been fighting at Sorokino, the 3rd Tank Corps had achieved a measure of success, crossed the Vytebet River, and begun fighting to capture Volosovo. As a result, the 15th Corps and the 154th were relocated to the Kumovo area on the right flank, and the 15th was tasked with exploiting the breakthrough to capture Perestryazh.


15th Tank Corps, Second formation, Kozelsk Offensive
The renewed attack began on 2 September but was delayed by German air attacks. Meanwhile, a regiment from the 264th Rifle Division proved unable to cross the Vytebet River and capture the village of Ozhigovo, which was necessary for the 15th Corps to exploit the breakthrough. This forced Koptsov to commit the 17th Motor Rifle Brigade and the 113th and 195th Brigades' motor rifle battalions to the battle. The motor rifle units crossed the Vytebet River after a short artillery barrage and captured Ozhigovo by the end of the day.


15th Tank Corps, Second formation, Kozelsk Offensive
The 195th Brigade's tank battalions moved across the Vytebet River and attacked Perestryazh the next day, but were unable to capture the village because they were first halted by a ravine covered by German artillery, and were then counterattacked on their left flank by 40 German tanks. Although they repulsed the counterattack and destroyed 13 tanks, the 195th's advance was stopped.


15th Tank Corps, Second formation, Kozelsk Offensive
On 4 September, after the 3rd Tank Corps was pulled out of the line due to losses and the main forces of the 264th arrived to hold Ozhigovo, the 15th's 17th and 113th Brigades were moved to the Volosovo area, having received orders to advance on Trostyanka alongside the 342nd Rifle Division. From 5 to 9 September, the corps attempted to advance, but was repeatedly repulsed, sustaining casualties and suffering fuel and ammunition shortages. The Kozelsk Offensive ended on 9 September with the combined Soviet tank units from all three armies left with only 200 tanks out of the 700 they originally fielded.


15th Tank Corps, Second formation, Interlude
The corps was relocated to the forests west of Kaluga beginning on 20 September 1942 after the 3rd Tank Army became part of the Reserve of the Supreme High Command. Around this time, the 17th Motor Rifle Brigade was transferred to another unit, and the 105th Brigade became part of the 5th Tank Army. A few days after arriving in the Kaluga area, Major General Pavel Rybalko replaced Romanenko, who became commander of the 5th Tank Army.


15th Tank Corps, Second formation, Interlude
The 15th rested and conducted training while refitting with supplies and equipment for the next several months, and was relocated to the Plavsk region on 22 October, remaining there until 26 December. The 88th Tank Brigade joined the corps at the end of November and the 52nd Motor Rifle Brigade joined in mid-December, bringing the corps back up to strength.


15th Tank Corps, Second formation, Interlude
On 22 December, the corps and the army began relocation to the Kalach and then the Kantemirovka areas, part of the Voronezh Front, to participate in the upcoming Ostrogozhsk–Rossosh Offensive, which was aimed to defeat Axis forces on the Upper Don. From 29 December to 13 January 1943, the corps was unloaded at the Kalach railway station. The relocation of the entire army was completed only on 15 January, due to a shortage of trains and railway congestion.


15th Tank Corps, Second formation, Ostrogozhsk–Rossosh Offensive
For the offensive, the corps was reinforced by the 368th Fighter Anti-Tank Artillery Regiment, the 71st Anti - Aircraft Artillery Regiment, and the 47th Engineer Battalion. They were to make a breakthrough on the first day in the area between the advance of the 48th Guards and 184th Rifle Divisions, seizing Yekaterinovka and advancing on Varvarovka and Alexeyevka by the end of the day. The attack was scheduled to begin on 12 January 1943, but was moved back two days owing to railroad delays.


15th Tank Corps, Second formation, Ostrogozhsk–Rossosh Offensive
By 13 January, 122 tanks from the army—most belonging to the corps' 113th and 195th Brigades—were still delayed by maintenance issues. This was because the Voronezh Front's initial offensive planning mandating that only the 12th Tank Corps would fight in the first attack, which resulted in the new tanks of the 15th being transferred to the 12th and the 12th's worn-out tanks to the 15th, although it was later decided that the entire army would fight in the operation.


15th Tank Corps, Second formation, Ostrogozhsk–Rossosh Offensive
The 15th therefore had much less time to reorganize in preparation for the assault, and as a result of the 113th and 195th Brigades arriving in the concentration areas on 13 January with only 10 to 12 tanks due to the delays, all of the serviceable tanks were transferred to the 88th Tank Brigade, which was brought up to a strength of 74 tanks. This single brigade constituted the entirety of the corps' armored troops involved in the first day's attack, as the 113th and 195th were placed in army reserve until their tanks arrived.


15th Tank Corps, Second formation, Ostrogozhsk–Rossosh Offensive
The corps fought in the offensive from 14 January, tasked with advancing into the Axis rear and linking up with the 40th Army attacking from the north. On the first day, the corps attacked the XXIV Panzer Corps, overrunning its command post and killing its commander during a 20-kilometer (12 mi) advance. After taking Alexandrovka, the corps cut the Rossosh–Alexandrovka–Rovenki highway on 15 January by capturing Yeremovka.


15th Tank Corps, Second formation, Ostrogozhsk–Rossosh Offensive
According to the 15th Tank Corps' reports, it had killed up to 600 Axis troops, captured 98 prisoners, 17 guns, 10 mortars, and 279 motor vehicles, and disabled five guns and 14 machine guns. This came at a cost of eight killed, 38 wounded, and one tank and three motor vehicles destroyed. The 15th then fought in the area of Olkhovatka and Sheliakino, during which it reported killing up to 950 German troops, capturing 2,100 prisoners, 1,200 motor vehicles, 1,856 rifles, 75 machine guns, 20 guns, and eight tanks.


15th Tank Corps, Second formation, Ostrogozhsk–Rossosh Offensive
The 15th suffered losses during this period of 11 killed, 41 wounded, and one tank and one armored vehicle disabled. Operating in conjunction with the 12th Tank Corps, the 15th broke through German defenses and on 17 January closed the encirclement ring, linking up with troops from the 40th Army's 305th Rifle Division at Alexeyevka. This cut off the retreat for the Italian Alpini Corps and thousands of Hungarian and German troops.


15th Tank Corps, Second formation, Ostrogozhsk–Rossosh Offensive
During the action, it reported killing 6,506 Axis troops, capturing 11,168, and capturing or destroying large amounts of artillery, weapons, equipment and transport, while losing 132 killed, 212 wounded, 39 missing, 14 tanks, six guns, two mortars, three armored vehicles, 10 motor vehicles, and six machine guns. Until the end of 25 January, the corps fought in the reduction of the Axis pocket north of Alexeyevka and began reconcentrating on the morning of 29 January. After marching 120 kilometers (75 mi) in two days, it concentrated in the Valuyki area.


15th Tank Corps, Second formation, Operation Star
The corps continued its advance towards Kharkov after the end of the Ostrogozhsk–Rossosh Offensive, against increasingly stiffening resistance from the SS-Panzer Corps. On 2 February, Operation Star began, the corps in the second echelon of the army as it needed refitting. The 15th went into action on 3 February, a day earlier than planned, without its refitting completed, as army commander Lieutenant General Pavel Rybalko quickened the pace of the offensive to prevent German reinforcements establishing a defensive line on the Donets.


15th Tank Corps, Second formation, Operation Star
The 15th Tank Corps advanced with the 160th Rifle Division towards Veliky Burluk and the Donets crossings at Pechengi. The corps crossed the Burlik River on 3 February and the next day captured Veliky Burluk from the 2nd SS Panzer Division Das Reich. At the same time the lead force of the 195th Tank Brigade, advancing 25 kilometers (16 mi) ahead of the remainder of the corps, reached German positions held by the 1st SS Panzer Division Leibstandarte SS Adolf Hitler (LSSAH) opposite Pechengi.


15th Tank Corps, Second formation, Operation Star
The brigade attempted to capture a crossing over the Pechengi with support from the 160th during the evening, but was repulsed with heavy losses. The rest of the 15th Corps and 160th Division arrived there during 5 February, and at first light on 6 February, they attacked after a short artillery bombardment, but were again repulsed. On the night of 9/10 February, the corps and the 160th Division secured the crossing sites and captured Pechengi. The corps reported 650 German soldiers killed during the fighting, at a cost of 350 killed and wounded. The 15th then pursued the retreating units of the LSSAH but the advance was stopped by German defenses at Rogan only 10 kilometers (6.2 mi) east of Kharkov.


15th Tank Corps, Second formation, Operation Star
On 12 February, Rybalko began a new attack with the 15th Corps, 48th Guards Rifle Division, and the 160th attacking the eastern part of Kharkov. They pushed the LSSAH back to the inner defensive line of the city and reached the factory district in the city's eastern suburbs. Two days later, front commander Colonel General Filipp Golikov ordered a final assault, and the corps together with the 160th renewed the attack from the east. They entered eastern Kharkov itself late on 15 February, participating in heavy street fighting with the forces of the Das Reich Division. The city was recaptured the next day, the 88th Tank Brigade taking Dzerzhinsky Square and linking up with the 40th Army's 183rd Rifle Division.


15th Tank Corps, Second formation, Operation Star
The 15th then pursued retreating German forces in the direction of Poltava. Late on 16 February, it captured Zalyutino and engaged German troops at Pesochnya on the road to Liubotyn. After capturing Pesochnya two days later, the 15th began the battle for Liubotyn against troops of the Grossdeutschland Division, but became bogged down in heavy fighting for the city. The corps' 195th Tank Brigade and the 160th Division were ordered to bypass the city and attempt to capture Staryi Merchik.


15th Tank Corps, Second formation, Operation Star
On 21 February, they advanced on Liubotyn from the west, and the Grossdeutschland Division began its retreat from the city on the next day. In the battle for Liubotyn between 21 and 22 February, the corps reported killing 400 German soldiers and destroying 12 tanks, while suffering losses of 360 killed and wounded and six tanks.


15th Tank Corps, Second formation, Third Battle of Kharkov
On 23 February 1943, German troops from the 4th Panzer Army counterattacked the Southwestern Front troops exploiting the breakthrough to the south of Kharkov, encircling many and forcing the remainder to retreat towards the Donets, beginning the Third Battle of Kharkov. The 3rd Tank Army was ordered to relieve the encircled troops, and the 15th Tank Corps changed direction, advancing towards Krasnograd. During the last days of February, the corps fought in a fierce meeting engagement with the LSSAH and 320th Infantry Division. Operating alongside the 111th Rifle Division, the 15th captured Novaya Vodolaga and on 26 February resumed its advance south, leaving the 195th Brigade to hold Novaya Vodolaga.


15th Tank Corps, Second formation, Third Battle of Kharkov
By the end of 28 February, in conjunction with the 219th Rifle Division, the corps had captured Kegichevka, at the cost of heavy losses for the 88th Tank Brigade. The 88th was left with three T-34 tanks and two T-70s, and the other brigades were down to similar strength, leaving the entire corps with 19 tanks. Koptsov was severely wounded during the fighting on 28 February, and corps chief of staff Lieutenant Colonel Alexander Lozovsky became acting commander.


15th Tank Corps, Second formation, Third Battle of Kharkov
By 2 March, the corps had been surrounded by the SS Panzer Corps east of Krasnograd and German tanks were in its rear at Lozovaya. Koptsov ordered the corps to defend the area around Kegichevka, the location of its headquarters. The 3rd Tank Army was completely surrounded and could not be relieved as it comprised most of the front's troops. Koptsov ordered a breakout, and a small number of troops with light weapons escaped the encirclement, all of the corps' 25 remaining tanks being lost. Koptsov himself was briefly captured on 2 March before dying of the wound he had received four days earlier.


15th Tank Corps, Second formation, Third Battle of Kharkov
Meanwhile, the 195th Tank Brigade's commander took command of 32 repaired and recovered tanks from the 12th and 15th Corps at Novaya Vodolaga, defending the town alongside the 253rd Rifle Brigade. There, they withstood three days of attacks from LSSAH until 6 March, when their positions began to be encircled by LSSAH and the SS-Totenkopf Division. During the next few days the brigade retreated north of the Mzha River to Rakitnoye, which was given up on 9 March. The 195th then took up defensive positions in the Ozeryanka area.


15th Tank Corps, Second formation, Operation Kutuzov
According to a report by the 3rd Tank Army's headquarters, the 15th Tanks Corps' strength on 14 March 1943 was only 1,000 men. By the following day, the remnants of the 15th had been concentrated in the Belyi Kholodets area, and on 21 March were moved to the Nikitovka, Samarino, and Chepukhino region for rest and refitting. On 31 March the corps was ordered to become part of the Reserve of the Supreme High Command in the Tambov area by 4 April. Instead, by the beginning of May it had been transferred to the Moscow Military District. The corps became part of the new 3rd Guards Tank Army within the month, and Major General Filipp Rudkin took command on 11 June. By 1 July, the corps had been rebuilt to a strength of 209 tanks and 16 self-propelled guns.


15th Tank Corps, Second formation, Operation Kutuzov
On 13 July, the corps became part of the Bryansk Front along with its army, and was ordered to concentrate in the Novosil area by the end of 15 July, in preparation for Operation Kutuzov, the Soviet counteroffensive after the Battle of Kursk. After completing a march to its jumping-off point, the corps attacked on the morning of 19 July. The 12th and 15th Tank Corps crossed the Oleshen River in the first echelon of the assault and advanced 12 kilometers (7.5 mi) by the end of the day, aided by artillery and air support.


15th Tank Corps, Second formation, Operation Kutuzov
In the evening, the 15th's advance was stopped by the 8th Panzer Division. During the fighting on 19 July, the commander of the 113th Tank Brigade, Leonid Chigin, was killed in action. The strong German resistance during the day reduced the corps to 32 T-34 and 42 T-70 tanks from a strength of 129 T-34s and 68 T-70s at the start of the day.


15th Tank Corps, Second formation, Operation Kutuzov
The following day, the corps shifted northwest to capture Otrada, cutting the Mtsensk–Oryol highway in the Vysokoye area. In the evening, the 52nd Motor Rifle Brigade crossed the Oka River, capturing a bridgehead near Novaya Slobodka. By the end of 21 July, the corps arrived to assist the 12th Tank Corps and the 91st Separate Tank Brigade in the crossing of the Optushka River, delayed by intense German air attacks and tank counterattacks. The next morning, all three units began crossing the river. The 195th Tank Brigade's commander, Vasily Lomakin, was killed in action leading his unit on 22 July. Both Chigin and Lomakin were posthumously awarded the title Hero of the Soviet Union. On 23 July, the German defenses on the Optushka were broken, and the pursuit began. By the end of the day, the corps had reached the line of Semendyaevsky, Karpovsky, Aleksandrovka, Safonovo, and Neplyuevo.


15th Tank Corps, Second formation, Operation Kutuzov
The actions of the offensive had still failed to produce a decisive breakthrough for the army, and on 23 July the attack was shifted south, the 15th being ordered to march to concentration points at Zarya and in the Petrovo area. The march took place on the night of 23/24 July, the troops arriving on the morning of 24 July. The advance was renewed the next day, the 15th in the second echelon behind the 12th Corps. On 26 July 1943, the corps was converted into the 7th Guards Tank Corps simultaneously with the 12th Tank Corps, becoming part of the elite Soviet Guards, in recognition of the "courage and bravery" of its actions in the offensive.


15th Tank Corps, Commanders
The corps' first formation was commanded by the following officer:


15th Tank Corps, Commanders
The corps' second formation was commanded by the following officers:


15th Tennessee Infantry Regiment
The 15th Regiment, Tennessee Infantry was an infantry regiment from Tennessee that served with the Confederate States Army in the American Civil War. Among its notable battles were the Battle of Shiloh and the Battle of Chickamauga.


15th Tennessee Infantry Regiment
Company G, of the regiment was composed largely of residents of states outside Tennessee. Besides men from Tennessee, Missouri, and Kentucky, the company (originally named the "Illinois Company") included soldiers from the consistently Union states of Illinois, Minnesota, and Pennsylvania.


15th Test Squadron
The 15th Test Squadron is an inactive United States Air Force unit. Its last assignment was with the Air Force Materiel Command at Hill Air Force Base, Utah, where it was inactivated.


15th Test Squadron, History, World War II
The squadron was activated as the 15th Pursuit Squadron in early 1941 as part of the Southeast Air District. It was equipped with a series of pursuit aircraft with a mission of air defense of Florida. After the Pearl Harbor Attack, the squadron was assigned to the Caribbean Air Force in Panama where it operated in defense of the Panama Canal. It returned to the United States in early 1943 where it became a Republic P-47 Thunderbolt (later North American P-51 Mustang) replacement training unit  for III Fighter Command. It was disbanded on 1 May 1944 as part of a reorganization of training units.


15th Test Squadron, History, Air Defense
The squadron was reactivated in 1953 as the 15th Fighter-Interceptor Squadron, part of Air Defense Command. It was equipped with North American F-86A Sabre day fighters at Davis-Monthan Air Force Base, Arizona with a mission of air defense of the Southwest United States. It Re-equipped in 1954 with North American F-86D Sabres. In 1957 it began re-equipping with the F-86L, an improved version of the F-86D which incorporated the Semi Automatic Ground Environment, or SAGE computer-controlled direction system for intercepts. The service of the F-86L destined to be quite brief, since by the time the last F-86L conversion was delivered, the type was already being phased out in favor of supersonic interceptors.


15th Test Squadron, History, Air Defense
In 1960 the squadron received the new McDonnell F-101B Voodoo supersonic interceptor, and the F-101F operational and conversion trainer. The two-seat trainer version was equipped with dual controls, but carried the same armament as the F-101B and were fully combat-capable. On 22 October 1962, before President John F. Kennedy told Americans that missiles were in place in Cuba, the squadron dispersed one third of its force, equipped with nuclear tipped missiles to Williams Air Force Base at the start of the Cuban Missile Crisis. These planes returned to Davis-Monthan after the crisis.


15th Test Squadron, History, Air Defense
In the early 1960s, the Air Force implemented Project Clearwater, an initiative to withdraw Convair F-102 Delta Daggers from overseas bases in order to reduce "gold flow" (negative foreign currency transactions). By 1963, part of this plan called for the 16th Fighter-Interceptor Squadron at Naha Air Base to move to Davis-Monthan, permitting the 15th's F-101s to be distributed to other ADC squadrons. Because there would be a gap between the transfer of the 15th's F-101s and the arrival of the 16th's F-102s, eight F-102s from Perrin Air Force Base would maintain alert at Davis-Monthan.


15th Test Squadron, History, Air Defense
As another cost saving move, planning called for the 16th to be inactivated upon arrival at Davis-Monthan and the 15th to assume its aircraft. However, the Gulf of Tonkin Incident intervened and the 16th was kept in the Pacific to maintain an air defense capability there. Headquarters, USAF directed ADC to simply inactivate the 15th with no replacement. The squadron degraded to a marginally combat ready status by October 1964 and was inactivated in December.


15th Test Squadron, History, Flight test operations
The 2872d Test Squadron was activated at Hill Air Force Base, Utah to perform flight tests on General Dynamics F-16 Fighting Falcons that had undergone major overhaul or modification. In 1992 the squadron was consolidated with the 15th Fighter-Interceptor Squadron as the 15th Test Squadron.

15th Texas Cavalry Regiment
The 15th Texas Cavalry Regiment was a unit of cavalry volunteers mustered into the Confederate States Army in March 1862 and fought during the American Civil War. In July 1862 the unit was dismounted and served the remainder of the war as infantry. The regiment was captured at Arkansas Post in January 1863. After being exchanged three months later, the much-reduced 15th Texas was consolidated with two other regiments and assigned to Patrick Cleburne's division in the Army of Tennessee. The consolidated regiment fought at Chickamauga, Missionary Ridge, and Ringgold Gap in 1863. After a re-consolidation, the regiment fought in the Atlanta Campaign, and at Franklin and Nashville in 1864. After a final consolidation the troops fought at Averasborough and Bentonville in 1865. The regiment's 43 surviving soldiers surrendered to Federal forces on 26 April 1865.


15th Texas Cavalry Regiment, History, Formation
George H. Sweet briefly served as a private in the Texas Brigade in the Eastern Theater of the American Civil War. A newspaperman from San Antonio, Sweet obtained an officer's commission and authority to raise his own regiment before returning to Texas. Starting in January 1862, he had little trouble raising ten companies of soldiers. The volunteers equipped themselves with their own horses and gear. As they drilled on courthouse squares, the recruits presented a rather motley appearance. On 10 March 1862, the 15th Texas Cavalry Regiment was accepted into Confederate service at McKinney, Texas. One volunteer recalled that many of the soldiers were middle aged men and boys.


15th Texas Cavalry Regiment, History, 1862–1863
After the regiment moved into Arkansas, it became subject to the First Conscription Act and was reorganized on 20 May 1862. Due to the Act, about 100 soldiers were discharged for being too young or too old. The Act also specified that the soldiers could elect their own officers. Sweet was reelected colonel, George Bibb Pickett became lieutenant colonel, and William Henry Cathey became major. Soon afterward, Pickett of Wise County was sent home to Decatur, Texas to recruit.


15th Texas Cavalry Regiment, History, 1862–1863
On 8 July 1862, the regiment was involved in a skirmish with Federal forces at Batesville, Arkansas in which eight men were killed and seven wounded. Sweet commended Captain Valerius P. Sanders of A Company for "coolness and bravery" under fire. A Union force under Samuel Ryan Curtis numbering 6,000 infantry, 3,000 cavalry, and 1,000 artillerymen occupied Batesville by 1 June. Hoping to cut off Curtis's troops from supplies, Thomas C. Hindman ordered Sweet's regiment to cross the White River above Batesville.


15th Texas Cavalry Regiment, History, 1862–1863
Hindman claimed 200 Union troops were captured and a number of wagons were captured before Cadwallader C. Washburn's Union cavalry brigade compelled the Texans to retreat. Soon after, on 24 July, the regiment was dismounted and the men's horses sent home. The soldiers were never remounted and served through the rest of the war as infantry. Cathey resigned for health reasons on 21 October 1862 and was replaced as major by Sanders.


15th Texas Cavalry Regiment, History, 1862–1863
The 15th Texas Cavalry was ordered to garrison Arkansas Post in the late fall of 1862. The place proved to be a very unhealthy campsite and over 100 men from the regiment died from disease while others were sent home as unfit for duty. About this time, Colonel Sweet left the regiment on detached duty and ended the war as superintendent of Camp Ford, a prisoner-of-war camp. The 15th Texas Cavalry under Major Sanders was assigned to James Deshler's brigade along with the 10th Texas Infantry, and the 17th and 18th Texas Cavalry Regiments, fighting dismounted.


15th Texas Cavalry Regiment, History, 1862–1863
In the Battle of Arkansas Post, 30,000 Federal troops led by John Alexander McClernand and 13 gunboats under David Dixon Porter attacked the 5,000 Confederate defenders under Thomas James Churchill. The Union expedition steamed up the Arkansas River in 50 transports and on 9 January 1863 landed the soldiers downstream from the post. The next day, the Federal troops began to envelop the Confederate defenses. That night Churchill received orders to hold Arkansas Post at all costs. On 11 January 1863, a joint land and naval assault silenced Fort Hindman's guns and overwhelmed the defenders, forcing 4,791 Confederates to surrender. Federal casualties numbered 1,061.


15th Texas Cavalry Regiment, History, 1862–1863
In the 15th Texas Cavalry 27 officers and 436 rank and file became prisoners of war. The regiment's number of killed and wounded is unknown, but Assistant Surgeon Nathan Wyncoope was fatally wounded during the fighting. The officers were sent to Camp Chase in Ohio, while the enlisted men traveled to Camp Douglas in Chicago. About 700 of the captured Texans died in only two months of captivity, including approximately 100 men from the 15th Texas Cavalry.


15th Texas Cavalry Regiment, History, 1862–1863
The death toll was made worse because a number of the men caught pneumonia and other illnesses on the trip up the river and because few of the men had blankets. On 3 April 1863, the surviving rank and file were sent to City Point, Virginia for prisoner exchange and on 29 April the officers were sent to Fort Delaware. The ordeal of the enlisted men was worse than that of the officers. Many of the survivors were so ill that they subsequently died or were discharged sick. Because this resulted in a surplus of officers, about two-thirds of the officers were sent back to Texas. The remaining soldiers of the 15th Texas Cavalry were consolidated into a single regiment together with the 6th Texas and 10th Texas Infantry. Major Sanders stayed with the new formation.


15th Texas Cavalry Regiment, History, 1863–1865
Patrick Cleburne decided that the Texans were, "a fine body of men out of which good soldiers are made", and accepted them into his division. The consolidated 6th-10th-15th Texas was sent to Wartrace, Tennessee for training. During the Battle of Chickamauga on 19–20 September 1863, the consolidated regiment was led by Colonel Roger Q. Mills and the brigade was led by Deshler. Brigade losses were 52 killed and 366 wounded, a total of 418 casualties. Deshler was killed, so Mills assumed command of the brigade and Lieutenant Colonel T. Scott Anderson took command of the 6th-10th-15th Texas. The other units in the brigade were the 19th and 24th Consolidated Arkansas Infantry Regiment and the 17th-18th-24th-25th Consolidated Texas Cavalry Regiment (dismounted).


15th Texas Cavalry Regiment, History, 1863–1865
Deshler's brigade was ordered to advance at nightfall on the first day of Chickamauga. The brigade's skirmish line, moving ahead of the battle line, stumbled into one of Richard W. Johnson's Union brigades in the dark woods and most of the skirmishers were captured. In very confused fighting, Deshler's brigade drifted to the left of its intended track. However, one of its regiments helped capture the colonel and 82 men of the 77th Pennsylvania Infantry Regiment. Some of the captured skirmishers escaped in a highly fluid situation.


15th Texas Cavalry Regiment, History, 1863–1865
On the second day, Cleburne ordered Deshler's brigade forward to cover the retreat of two brigades that had been driven off. As the brigade reached the crest of a rise, it was struck by a blast of Federal bullets. Cleburne sent orders to Deshler to hold out as long as possible, so the soldiers dropped to the ground and returned fire. For two hours and 30 minutes, Deshler's men held the line, but they suffered hundreds of casualties. Deshler was struck in the chest by an artillery projectile and killed instantly. At 2:00 pm Mills ordered most of the brigade to pull back 20 yd (18 m) and assigned a few sharpshooters to hold the crest. At Chickamauga, the 15th Texas lost five killed, 16 wounded, and 14 captured or missing.


15th Texas Cavalry Regiment, History, 1863–1865
The 6th-10th-15th Texas fought with distinction at the Battle of Missionary Ridge on 24–25 November 1863. The regiment formed part of a brigade under James Argyle Smith together with the 17th-18th-24th-25th Texas Cavalry (dismounted) and the 7th Texas Infantry Regiment. Early on 24 November, William T. Sherman's Union troops crossed the Tennessee River and advanced toward the northern end of Missionary Ridge. The commander of the Confederate Army of Tennessee, Braxton Bragg reacted slowly, but he finally ordered Cleburne to halt Sherman's forces.


15th Texas Cavalry Regiment, History, 1863–1865
In the late afternoon, Cleburne deployed Smith's brigade on Tunnel Hill just in time to block Union soldiers from occupying it. Following some skirmishing, Sherman sent John M. Corse's brigade to attack Smith's Texans about 10:30 am on 25 November. A brief counterattack threw the Union troops back, but Smith and Colonel Mills were seriously wounded and Hiram B. Granbury of the 7th Texas took command of the Texas brigade. After Mills fell, Captain John R. Kennard assumed command of the 6th-10th-15th Texas. Major Sanders was shot and had to have his right arm amputated.


15th Texas Cavalry Regiment, History, 1863–1865
The initial fighting was followed by uncoordinated and unsuccessful assaults by several Federal brigades. Confederate reinforcements soon arrived, but, as related by another Southern soldier, the Texans were reluctant to give up their position in the front line because, "it was the first time they ever had a chance to fight the Yankees from behind breastworks and that they were rather enjoying it". At 4:00 pm, Cleburne launched a major counterattack by striking the Federals' foothold with Alfred Cumming's brigade in front and the 6th-10th-15th Texas on the right flank. The effort proved entirely successful and chased the Union troops off Tunnel Hill, capturing many prisoners. The 15th Texas sustained losses of one killed, seven wounded, and two missing.


15th Texas Cavalry Regiment, History, 1863–1865
The 6th-10th-15th Texas fought at the Battle of Ringgold Gap on 27 November 1863. Cleburne deployed Granbury's brigade just to the north of the gap. Attacked by Charles R. Woods's Federal brigade, the Texans opened fire and routed the three leading Missouri regiments. At Ringgold Gap, the 15th Texas lost four men wounded and one captured. During the Atlanta Campaign in 1864, the 15th Texas Cavalry remained consolidated with the 6th Texas Infantry, but the 10th Texas became an independent regiment again.


15th Texas Cavalry Regiment, History, 1863–1865
At different times during the campaign, the 6th-15th Texas was commanded by Captains R. Fisher, Matthew M. Houston, J. W. Terrill, R. B. Tyus, S. E. Rice, and Lieutenant T. L. Flint. The Texas brigade, which consisted of the 7th and 10th Infantry, and the 17th-18th and 24th-25th Dismounted Cavalry, was led by Smith, Granbury, and Robert B. Young at various times.


15th Texas Cavalry Regiment, History, 1863–1865
The 6th-15th Texas fought at the Battle of Rocky Face Ridge, the Battle of Resaca, the Battle of Pickett's Mill, the Battle of Dallas, the Battle of Kennesaw Mountain, the Battle of Peachtree Creek, the Battle of Atlanta, and the Battle of Jonesborough. In these actions, the 15th Texas lost 13 killed, 58 wounded, and three captured.


15th Texas Cavalry Regiment, History, 1863–1865
After the fall of Atlanta, John Bell Hood mounted an invasion of Tennessee in the Franklin–Nashville Campaign. On 30 November, Hood launched a 3:30 pm assault with 38,000 men against 32,000 entrenched Federals under John Schofield. In the Battle of Franklin, the divisions of Cleburne and John C. Brown overran the Union rearguard and broke into the enemy position but were finally driven out by reserve formations. Nevertheless, repeated assaults continued until 9:00 pm when Hood called a halt. The Confederates suffered 6,252 casualties while Union losses were 2,326 of whom half were prisoners.


15th Texas Cavalry Regiment, History, 1863–1865
Cleburne, Granbury, and three other Confederate generals were killed. Granbury's brigade started the battle with 1,100 soldiers but ended it with only 450. The 15th Texas lost seven killed including Captain Houston, 10 wounded, and 13 missing. At the Battle of Nashville on 15–16 December, the division was led by Smith while the Granbury's former brigade was led by Captain E. T. Broughton and the 6th-15th Texas was commanded by Captain Tyus.


15th Texas Cavalry Regiment, History, 1863–1865
In the Campaign of the Carolinas, the survivors of the Texas brigade were consolidated into a single unit, the 1st Texas under Lieutenant Colonel W. A. Ryan. The 1st Texas was part of Daniel Govan's brigade in Brown's division. Sherman's 60,000 Federal troops marched from Savannah, Georgia, through South Carolina, and into North Carolina before encountering significant resistance from 21,000 Confederate troops at the Battle of Averasborough on 16 March 1865 and the Battle of Bentonville on 19–21 March. Confederate army commander Joseph E. Johnston surrendered to Sherman on 26 April 1865. At the surrender, the 15th Texas Cavalry counted three officers, eight non-commissioned officers, 30 enlisted men, and two teamsters. Altogether, 1,200 men served in the regiment during the war. The last survivor of the 15th Cavalry, Alonzo L. Steele of Company F died on 6 December 1936 at Baytown, Texas.


15th The King's Hussars
The 15th The King's Hussars was a cavalry regiment in the British Army. First raised in 1759, it saw service over two centuries, including the First World War, before being amalgamated with the 19th Royal Hussars into the 15th/19th The King's Royal Hussars in 1922.


15th The King's Hussars, History, Early wars
The regiment was raised in the London area by George Augustus Eliott, 1st Baron Heathfield as Elliots Light Horse as the first of the new regiments of light dragoons in 1759. It was renamed the 15th Regiment of (Light) Dragoons in 1760. The regiment landed in Bremen in June 1760 for service in the Seven Years' War. The regiment were largely responsible for the victory, suffering 125 of the 186 allied casualties at the Battle of Emsdorf in July 1760.


15th The King's Hussars, History, Early wars
Lieutenant Colonel William Erskine, commanding the regiment, presented King George III with 16 colours captured by his regiment after the battle. During the battle the French commander, Major-General Christian-Sigismund von Glaubitz, was taken prisoner. The regiment charged the French rear guard twice at the Battle of Wilhelmsthal in June 1762 and then returned home in July 1763. In 1766 it was renamed for King George III as the 1st (or The King's Royal) Regiment of Light Dragoons, the number being an attempt to create a new numbering system for the light dragoon regiments. However, the old system was quickly re-established, with the regiment returning as the 15th (The King's) Regiment of (Light) Dragoons in 1769.


15th The King's Hussars, History, Early wars
The regiment landed at Ostend in May 1793 for service in the Flanders Campaign and fought at the Battle of Famars in May 1793. It formed part of the besieging force at the Siege of Valenciennes in June 1793 and formed part of the covering force at the Siege of Dunkirk in August 1793 and at the Siege of Landrecies in April 1794. It undertook successful charges at the Battle of Villers-en-Cauchies in April 1794 and at the Battle of Willems in May 1794 and was present, but not actively engaged, at the Battle of Tournay later in May 1794. The regiment returned to England in December 1795 and was next in action at the Battle of Alkmaar in October 1799 during the Anglo-Russian invasion of Holland.


15th The King's Hussars, History, Napoleonic Wars
The regiment was reconstituted as a hussar regiment in 1807 as the 15th (The King's) Regiment of (Light) Dragoons (Hussars). It landed at Corunna in November 1808 for service in the Peninsular War and defeated two regiments of French cavalry at the Battle of Sahagún in December 1808. At the battle two French lieutenant colonels were captured and the French 1st Provisional Chasseurs à cheval, who lost many men captured, ceased to exist as a viable regiment. However, the commanding officer of the 15th Hussars, Colonel Colquhoun Grant, was wounded in the battle. The regiment embarked at Corunna for their journey home in January 1809.


15th The King's Hussars, History, Napoleonic Wars
The regiment were ordered to support Sir Arthur Wellesley's Army on the Iberian Peninsula and landed at Lisbon in February 1813.
