U.S. Air Force Airman 1st Class John Kulwatno, Gambler Aircraft Maintenance Unit crew chief, performs a basic post-and pre-flight inspection on an F-16 Fighting Falcon July 7 at Aviano Air Base, Italy. The Gambler AMU and the 77th Expeditionary Fighter Squadron from Shaw Air Force Base, S.C., supported Operation Unified Protector for more than five months from Aviano Air Base, Italy in enforcement of United Nations Security Council Resolutions 1970 and 1973. The goal of Operation Unified Protector is to protect civilians and civilian-populated areas in Libya under attack or threat of attack. The mission is focused on three main areas: an arms embargo, a no-fly-zone and actions to protect civilians from attack or the threat of attack. (U.S. Air Force photo/Staff Sgt.
