About this Unit
The Marine Advisory Unit, Vietnam, was established as part of the U.S. Marine Corps' efforts to support and train the South Vietnamese Marine Corps (VNMC) during the Vietnam War. Formally known as the U.S. Marine Advisory Unit, it operated under the Military Assistance Command, Vietnam (MACV) beginning in 1962. The unit's primary mission was to provide tactical and technical advice, assist in training, and coordinate operations between U.S. and Vietnamese Marine units. Marine advisors often accompanied Vietnamese Marines into combat, playing a crucial role in developing their operational capabilities until the withdrawal of U.S. forces in 1973.
