MACV SOG

Military Assistance Command, Vietnam – Studies and Observations Group (MACV-SOG) was a highly classified, multi-service United States special operations unit that operated during the Vietnam War from 1964 to 1972. Composed of personnel from the Army, Navy SEALs, Air Force, and Marine Corps, MACV-SOG conducted covert missions including strategic reconnaissance, direct action, psychological operations, and sabotage deep behind enemy lines in Vietnam, Laos, and Cambodia. The unit played a critical role in disrupting North Vietnamese supply routes, such as the Ho Chi Minh Trail, and gathering intelligence that influenced U.S. military strategy. Due to the secretive nature of its missions, much of MACV-SOG's history remained classified for decades, and its members are recognized today for their extraordinary bravery and ingenuity.
