Active-duty and Reserve leadership from across the Tinker Air Force Base community share stories and jokes prior to the big event Sept. 7, 2018. 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, ACG Airmen assigned work hand-in-hand with the active-duty 552nd Air Control Wing, contributing reliable AWACS support to numerous missions worldwide regularly.
