GC communication
Senior Airman Jeremiah Toney, 21st Space Communications Squadron technical controllers, performs an operational check on fiber cable inputs before the 2008 Guardian Challenge competition April 22 at Peterson Air Force Base, Colo. Together with his wingman Senior Airman Jack Needham, the Airmen are representing the 21st SCS as it competes against fellow communication squadrons at Buckley and Schriever AFBs in Colorado. The competition allows inspectors to determine which communications squadron is best at supporting a space mission through technical control functions.
