A KC-135 Stratotanker from the 100th Air Refueling Wing, RAF Mildenhall, England, refuels an F-16 Fighting Falcon from the 31st Fighter Wing, Aviano Air Base, Italy, March 4, 2015, during Exercise Iron Hand over southern France. The aircraft were participating in a combined training event designed to enhance interoperability between the two wings and refine techniques and procedures. This type of planned, routine training allows a key opportunity for U.S. Air Forces in Europe –Air Forces Africa wings to work with each other to ensure assets are ready to conduct real-world missions effectively and efficiently when called upon.
