MACV RVN

**Military Assistance Command, Vietnam (MACV)** was a United States unified command structure established in 1962 to provide military assistance to the Republic of Vietnam (South Vietnam) during the Vietnam War. MACV assumed operational control over all U.S. military forces in Vietnam, including advisory, combat, and support units, and coordinated joint operations with the Army of the Republic of Vietnam (ARVN). Under successive commanders, MACV played a central role in the escalation of U.S. military involvement, including major campaigns such as Operation Rolling Thunder and the Tet Offensive. The command was dissolved in March 1973 following the Paris Peace Accords, marking the withdrawal of most U.S. forces from Vietnam.
