MACV stands for Military Assistance Command, Vietnam.
This command was established in 1962 to manage and coordinate U.S. military operations in South Vietnam during the Vietnam War.
The MACV was headed by a U.S. general and included representatives from various branches of the U.S. military as well as South Vietnamese military leaders.
The MACV played a significant role in the Vietnam War, overseeing the deployment of U.S. troops, providing military aid to South Vietnam, and conducting combat operations.
The MACV was dissolved in 1973 following the withdrawal of U.S. troops from Vietnam.
