During the Tet offensives of 1968 and 1969, Tropic Lightning soldiers were instrumental in defending the besieged city of Saigon. From May through June 1970, division soldiers participated in Allied thrusts deep into enemy sanctuaries located in Cambodia. In these Incursion operations, the division units confiscated thousands of tons of supplies and hundreds of weapons. This operation crippled the Cambodian-based efforts against American units. Following its return from Cambodia to South Vietnam, the division resumed its place in the Vietnamization Program. The war was winding down. By late December 1970, elements of the 25th Infantry Division were able to begin redeployment to Schofield Barracks. Second Brigade was the last element of the division to depart Vietnam. It arrived at Ft Lewis, Washington in the early days of May 1971. Some elements in the 2nd Brigade were originally assigned to the 4th Infantry Division when they arrived in Vietnam. During the war in Vietnam, 22 Medals of Honor were awarded to Tropic Lightning soldiers.
