Military Assistance Command, Vietnam – Studies and Observations Group (MACV-SOG)

Military Assistance Command, Vietnam – Studies and Observations Group (MACV-SOG) was a covert U.S. military unit during the Vietnam War focused on special operations. It specialized in reconnaissance, sabotage, and intelligence gathering in enemy territory, often behind enemy lines. Comprising mostly volunteers from various branches, MACV-SOG conducted secret missions in Vietnam, Laos, and Cambodia to gather critical information, rescue prisoners, and disrupt enemy activities. Its operations were highly classified, and much of its work remained undisclosed for many years, playing a vital role in U.S. strategic efforts during the conflict.
