Westmoreland (1964–68) and General Creighton Abrams (1968–72). • Phoenix Program: MAC-V supported the controversial Phoenix Program, aimed at dismantling the Viet Cong infrastructure through intelligence and counterinsurgency operations. • MAC-V SOG: The Studies and Observations Group (SOG) was a highly secretive MAC-V unit conducting covert operations across Vietnam, Laos, and Cambodia. • Joint Command: MAC-V was a joint command, integrating Army, Navy, Air Force, and Marine Corps units under a single headquarters, a unique arrangement for its time. • Advisory Teams: MAC-V deployed hundreds of advisory teams throughout South Vietnam, working directly with local military units at province and district levels. • Role in Tet Offensive: MAC-V headquarters in Saigon was a target during the 1968 Tet Offensive, underscoring its significance and the intensity of the conflict. • Dissolution: MAC-V was disbanded on March 29, 1973, following the withdrawal of U.S. combat forces, marking the end of direct American military involvement in the Vietnam War.
