Stargate Command (abbreviated to SGC) is a top-secret United States Air Force military organization tasked with operating the Stargate device and all matters pertaining to things offworld, such as threats to Earth or missions to procure new technology from extraterrestrial civilizations. It is based inside the Cheyenne Mountain Complex in Colorado, codenamed “Area 52”. (SG1: “Politics”)
The SGC base acts as the secure ground station for all Stargate activities. It is typically commanded by a Major General (O-8) and is staffed by subject matter experts and military support personnel, several elite special operations teams, and several SG teams, including SG-1, the SGC’s main flagship team.
