Patrick Daniel Tillman (November 6, 1976 - April 22, 2004) was a professional American football player in the National Football League (NFL) who left his sports career and enlisted in the United States Army in June 2002 in the aftermath of the September 11 attacks. His service in Iraq and Afghanistan, and subsequent death, were the subject of much media attention. Tillman joined the Army Rangers and served several tours in combat before he was killed in the mountains of Afghanistan. At first, the Army reported that Tillman had been killed by enemy fire.
Military career and death
Tillman and his brother Kevin enlisted on May 31, 2002. Kevin gave up the chance of a career in professional baseball as he had already signed to play for the Cleveland Indians. In September 2002, they completed basic training together. The two brothers completed the Ranger Indoctrination Program in late 2002 and were assigned to the 2nd Ranger Battalion in Fort Lewis, Washington. Tillman resided in University Place with his wife before being deployed to Iraq. After participating in the initial invasion of Iraq as part of Operation Iraqi Freedom, in September 2003, they entered Ranger School at Fort Benning, Georgia, and graduated on November 28, 2003.  Tillman was subsequently redeployed to Afghanistan, and based at FOB Salerno. On April 22, 2004, he was initially reported to have been killed by enemy combatants. An Afghan Militia Force allied soldier was also killed in the action. Tillman's platoon leader First Lieutenant David Uthlaut and his radio telephone operator (RTO), 19-year-old Jade Lane, were wounded in the incident. The Army initially claimed that Tillman and his unit were attacked in an apparent ambush on a road outside of the village of Sperah about 25 miles (40 km) southwest of Khost, near the Pakistan border. It was not until after his burial that investigations by the Department of Defense and U.S. Congress were launched, eventually ruling his death as friendly fire.  The Army Special Operations Command initially claimed that there was an exchange with hostile forces. After a lengthy investigation conducted by Brigadier General Gary M. Jones, the U.S. Department of Defense concluded that both the Afghan militia soldier's and Tillman's deaths were due to friendly fire aggravated by the intensity of the firefight.  An investigation by the U.S. Army Criminal Investigation Command (CID) concluded that Tillman and the Afghan militia soldier were killed by friendly fire when one allied group fired upon another in confusion after nearby gunfire was mistakenly believed to be from enemy combatants. The CID Report summary, dated March 19, 2007, stated that:  ...during their movement through the canyon road, Serial 2 [Tillman's platoon had to split up because of a broken Humvee; the parts were called Serial 1 and 2] was ambushed and became engaged in a running gun battle with enemy combatants. Serial 1 [Tillman's portion of the platoon] had just passed through the same canyon without incident and were approximately one kilometer ahead of Serial 2. Upon hearing explosions, gunfire, and sporadic radio communication from Serial 2, Serial 1 dismounted their vehicles and moved on foot, to a more advantageous position to provide overwatch and fire support for Serial 2's movement out of the ambush. Upon exiting the gorge, and despite attempts by Serial 1 to signal a "friendly position", occupants of the lead vehicle of Serial 2 opened fire on Tillman's position, where he was fatally shot.
