About this Unit
The United States Army, Vietnam (USARV) was established in 1966 as the Army component command of the United States Military Assistance Command, Vietnam (MACV). Its primary mission was to provide command and logistical support to all U.S. Army forces serving in the Republic of Vietnam during the Vietnam War. Headquartered at Long Binh, USARV managed combat operations, training, and supply lines, overseeing tens of thousands of soldiers at the peak of American involvement. The command was inactivated in March 1973 as U.S. forces withdrew, marking the end of major Army operations in Vietnam.
