The Studies and Observation Group, or SOG, is a military unit featured in Call of Duty: Black Ops.

History
The Studies and Observations Group (aka SOG, MACSOG, and MACV-SOG) were a joint unconventional warfare task force created on 24 January 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, the Central Intelligence Agency (CIA) Special Activities Division, and elements of the United States Marine Corps Force Reconnaissance units.
