A C-17 Globemaster III from Joint Base Charleston, S.C., approaches a KC-135R Stratotanker from the 434th Air Refueling Wing, Grissom Air Reserve Base, Ind., during an aerial refueling mission last year. By Oct. 1, 2011, Air Force Reserve Command will realign four flying wings, including Charleston’s 315th Airlift Wing, under 4th Air Force. The numbered air force is responsible for “strategic reach forces,” which includes aerial refueling and long-range, strategic airlift. (U.S. Air Force photo/Tech. Sgt. Mark R. W. Orders-Woempner)
