About this Unit
The United States Army Pacific (USARPAC) played a significant role during the Vietnam War, primarily through its oversight of logistics, command, and support to U.S. Army forces deployed in Southeast Asia. Established as a major Army command in the Pacific region, USARPAC coordinated the deployment and sustainment of troops, equipment, and supplies from bases in Hawaii and other Pacific locations to Vietnam. Throughout the conflict, USARPAC facilitated large-scale troop movements, managed replacements, and ensured operational readiness for combat units engaged in Vietnam. Its efforts were crucial to maintaining the Army's ability to conduct sustained operations during the Vietnam War from the early 1960s until the U.S. withdrawal in 1973.
