Description
The Studies and Observations Group (also known as SOG, MACSOG, and MACV-SOG) was a top secret, joint unconventional warfare task force created on ## ####### 1964 by the Joint Chiefs of Staff as a subsidiary command of the Military Assistance Command, Vietnam (MACV). The unit would eventually consist primarily of personnel from the United States Army Special Forces, the United States Navy SEALs, the United States Air Force (USAF), the Central Intelligence Agency (CIA), and elements of the United States Marine Corps Force Reconnaissance units. The Studies and Observation Group (as the unit was initially titled) was in fact controlled by the Special Assistant for Counterinsurgency and Special Activities (SACSA) and his staff at the Pentagon. This arrangement was necessary since SOG needed some listing in the MACV table of organization and the fact that MACV's commander, General William Westmoreland, had no authority to conduct operations outside territorial South Vietnam.
