4th Bn 31st Infantry - Vietnam Veteran Pin

The 4th Battalion went to Vietnam in the spring of 1967, operating initially in War Zone D and around Tay Ninh near the Cambodian border as a unit under the 196th Brigade(Sep). In 1967, the battalion moved north to help form the 23d "Americal" Infantry Division. Operating at Quang Ngai, Chu Lai, and the Que Son Valley for most of the rest of the war, the 4th Battalion fought to keep Viet Cong guerillas and the North Vietnamese Army from capturing the coastal lowlands. Two of the battalion's members earned the Medal of Honor almost a year apart near the bitterly contested village of Hiep Duc. When American forces departed, the 4th Battalion 31st Infantry was part of the last brigade to leave Vietnam. It was inactivated in 1971.
