The massive Long Binh military base, once the largest U.S. installation outside the continental United States, is handed over to the South Vietnamese. This logistical complex, which had been constructed on the outskirts of Bien Hoa near the outskirts of Saigon, included numerous ammunition depots, supply depots, and other logistics installations. It served as the headquarters for U.S. Army Vietnam, 1st Logistical Command, and several other related activities. The handing-over of the base effectively marked the end–after seven years–of direct U.S. participation in the war. After the Long Binh base was turned over, about 29,000 U.S. soldiers remained in South Vietnam, most them advisors with South Vietnamese units, or helicopter crewmen, and maintenance, supply, and office staff.
