The Military Assistance Command in Vietnam (MACV) was a joint-service command of the United States Department of Defense, created on the 6 February 1962. MACV was first implemented to assist the Military Assistance Advisory Group (MAAG) in Vietnam, controlling every advisory and assistance effort in Vietnam. MACV absorbed MAAG on 15 May 1964 when combat unit deployment became too large for MAAG control. MACV was disestablished on 29 March 1973 and replaced by the Defense Attaché Office Saigon which performed many of the same roles of MACV within the restrictions imposed by the Paris Peace Accords until the Fall of Saigon. Commanding generals of the MACV included General Paul D. Harkins (1962), General William C. Westmoreland (1964), General Creighton W. Abrams (1968) and General Frederick C. Weyand (1972).
