The South Vietnamese government requests that Washington double U.S. Military Assistance and Advisory Group (MAAG-Vietnam) strength from 342 to 685. The advisory group was formed on November 1, 1955 to provide military assistance to South Vietnam. It had replaced U.S. Military Assistance Advisory Group Indochina (MAAG-Indochina), which had been providing military assistance to "the forces of France and the Associated States in Indochina" (Cambodia, Laos and Vietnam) in accordance with President Harry S. Truman's order of June 27, 1950.
MAAG-Vietnam had U.S. Army, Navy, Air Force, and Marine Corps elements that provided advice and assistance to the South Vietnamese Ministry of Defense, Joint General Staff and corps and division commanders, as well as to training centers and province and district headquarters.
In May 1964, MAAG-Vietnam was disbanded and its personnel and responsibilities absorbed by the U.S. Military Assistance Command Vietnam (MACV), which had been established in Saigon two years earlier.
