Studies and Observation Group

The Military Assistance Command, Vietnam - Studies and Operation Group (also known as MACV-SOG or SOG) was a highly classified, multi-service United States special operations unit which conducted covert unconventional warfare operations during the Vietnam War. It is one of the main playable factions in Call of Duty: Black Ops and Call of Duty: Black Ops Cold War.
==Call of Duty: Black Ops==
S.O.G. makes their first appearance in the self-titled mission. According to Alex Mason's interrogator, Mason was picked to join the S.O.G. team lead by Frank Woods prior to the mission. During the mission, Woods briefs Mason (accompanied by Special Agent Hudson) on MACV-SOG's creation and purpose, when their base comes under attack by the NVA. The team decides to stay behind and aid the Marines in defending the base, which they do successfully.
The team travels to Hue City where they are given the objective of extracting a Soviet defector from the MACV compound. Mason and Woods are joined by fellow operative Joseph Bowman. Although the defector was killed, Mason acquires his dossier, and the team fight through the city to extraction by boat.
Later, Mason's and Woods' helicopter is shot down by Viet Cong. After escaping the crash and fighting Viet Cong on the river, Woods and Mason sneak into an enemy village where they stealthily kill guards and meet up with Bowman and other operatives. The two split up, with Woods working above water while Mason sets explosives underwater. After meeting up with Bowman and many other SOG operatives, the team detonates the explosives and proceeds to clear the village. The team encounters a "rat tunnel" and Mason and Swift enter to clear it out. Swift is killed, but Mason continued to clear the tunnel and escaped for extraction.
The SOG work with the US Army to attack Viet Cong villages, supporting from boats. Afterwards, they search for a downed Soviet plane which they believe carries Nova-6. Discovering the gas may have dissipated after the crash, they defend the plane from a Soviet attack, during which the team is captured.
The team is taken to a hidden cave in Laos and forced to play Russian Roulette. Bowman refuses, resulting in his death. Mason and Woods conceive an escape plan and make it out of the cave. They steal an enemy Hind, and use it to wreak havoc on various Viet Cong settlements. After landing, Woods and Mason rescue the POWs from Kravchenko's compound. The group then fights their way to Kravchenko himself, which culminates in the presumed death of Kravchenko.
Mason imagined Viktor Reznov being with him for the majority of the SOG's operations and apparently contacted the CIA informing them of "Reznov"'s presence, as Reznov is in the CIA files as having been the defector who joined the SOG team. However, Reznov was never truly there and Hudson corrected this once he realized that was the case.
===Multiplayer===
In multiplayer, the SOG announcer is Bowman. The MACV-SOG always play against the North Vietnamese Army.

It's confirmed that the SOG symbol on Harper's vest was just a placeholder in Call of Duty: Black Ops II, due to the fact SOG disbanded after the Vietnam War. Harper and David Mason are really members of the United States Navy Special Warfare Development Group as they both wear the same camouflage as the SEALS in Multiplayer.
