What was the name of the US military command in Vietnam from 1962 to 1973?

The U.S. military command in Vietnam from 1962 to 1973 was Military Assistance Command, Vietnam, commonly abbreviated MACV. It was the joint-service headquarters responsible for coordinating American military operations and assistance in South Vietnam.

MACV was created on February 8, 1962, as U.S. involvement expanded beyond the earlier advisory mission. Its first commander was General Paul D. Harkins. In 1964, as American combat deployments grew, MACV absorbed the separate Military Assistance Advisory Group, or MAAG, Vietnam.

The command oversaw forces from the Army, Navy, Air Force, and Marine Corps, along with major component organizations such as United States Army, Vietnam, and the Seventh Air Force. Generals William Westmoreland and Creighton Abrams later commanded MACV during the war’s most intensive years.

MACV was disestablished on March 29, 1973, after the Paris Peace Accords and the withdrawal of U.S. combat forces. MAAG was its predecessor, while USARV was an Army component command—not the overall U.S. command in Vietnam. “USMACV” is an informal rearrangement, not the canonical name.
