Headquartered at Long Binh, it was responsible for controlling all U.S. Army combat units in the III Corps Tactical Zone, which encompassed the area around Saigon. II Field Force directed large-scale operations against Viet Cong and North Vietnamese forces, including participation in the 1968 Tet Offensive and subsequent counteroffensives.
