31st Engineer Battalion. Long Binh. The Army’s Largest Base in Vietnam.
Long Binh Post — located northeast of Saigon in Bien Hoa Province — was the largest U.S. military installation in Vietnam, serving as the headquarters for U.S. Army Vietnam (USARV) and a massive logistics, support, and command hub for the entire war effort. For the 31st Engineer Combat Battalion, Long Binh represented the epicenter of the Army’s engineering mission in-country: building and maintaining the infrastructure of the largest military base in the theater, while remaining ready to respond to any threat in the surrounding III Corps Tactical Zone.
This mug honors the 31st Engineer Battalion’s service at Long Binh, Vietnam — a tribute to the engineers who built and sustained the Army’s most critical installation in Southeast Asia, where the scale of the mission matched the scale of the war itself.

About the Unit & Location
The 31st Engineer Battalion was originally constituted as the 31st Engineer Company on 1 July 1940 and activated at Fort Belvoir, Virginia. It was reorganized and redesignated as the 31st Engineer Combat Battalion on 15 December 1941. Long Binh Post, in Bien Hoa Province northeast of Saigon, was the headquarters of U.S. Army Vietnam (USARV) and the largest American military installation in the country — covering approximately 25 square miles at its peak. Combat engineers at Long Binh were responsible for the construction and maintenance of facilities, roads, and infrastructure that supported the entire U.S. Army effort in Vietnam.
