With a quick motion of oversized scissors, Col. Laurie Dickson, Commander, 513th Air Control Group, officially "opens" the new 513th ACG headquarters for business Sept. 7, 2018, at Tinker Air Force Base, Oklahoma. The 513th Air Control Group is the only Air Force Reserve unit to fly and maintain the E-3 Sentry, an Airborne Warning and Control System aircraft that provides surveillance, warning and tactical control of U.S. and allied military aircraft. As a Reserve associate unit, Airmen assigned to the 513th ACG work hand-in-hand with the active-duty 552nd Air Control Wing, which is responsible for the E-3 Sentry aircraft assigned to Tinker AFB. Working together, Tinker AFB's Team AWACS maintains a reliable presence in numerous missions worldwide. (Air Force photo by Master Sgt. Grady Epperly)
