Military Assistance Command, Vietnam (MACV) was a United States joint-service command established in February 1962 to provide military assistance and oversee U.S. operations in South Vietnam during the Vietnam War. Initially focused on advising and supporting the Army of the Republic of Vietnam (ARVN), MACV’s mission expanded as American troop deployments escalated dramatically after 1965. Under successive commanders, including Generals William Westmoreland and Creighton Abrams, MACV directed combat operations, coordinated with allied forces, and implemented pacification programs. The command was dissolved in March 1973 following the Paris Peace Accords, marking the end of major U.S. military involvement in Vietnam.
