The Military Assistance Command, Vietnam (MACV) was a United States unified command established in February 1962 to provide military assistance and advisory support to the Republic of Vietnam during the Vietnam War. MACV initially oversaw the expanding U.S. advisory effort, but as American involvement grew, it became responsible for all U.S. military operations in Vietnam. It coordinated the activities of the U.S. Army, Navy, Air Force, and Marine Corps, as well as allied forces from other nations. General William C. Westmoreland was among its most notable commanders. MACV was disbanded in March 1973 following the withdrawal of U.S. combat forces and the implementation of the Paris Peace Accords.
