HHC 5:46th Inf

Headquarters and Headquarters Company, 5th Battalion, 46th Infantry Regiment (HHC 5/46th Inf) was constituted during the expansion of the U.S. Army’s infantry force for service in the Vietnam War. Reactivated in 1967, the 5/46th Infantry was assigned to the Americal Division (23rd Infantry Division) and operated primarily in the Quang Ngai province, engaging in search-and-destroy missions and counterinsurgency operations. The battalion earned campaign participation credit for several major operations, including the Tet Counteroffensive and other phases of the Vietnam conflict. Following the drawdown of U.S. forces, the unit was inactivated in 1971 as part of the Army’s post-war reduction.
