OSAN AIR BASE, Republic of Korea --   The last two A-10C Thunderbolt II aircraft returned to the Korean Peninsula from Exercise COPE TIGER/Balikatan deployment April 21, 2011. This occasion marks the first time that all A-10C model aircraft assigned to Osan Air Base, Korea, have been on the peninsula at the same time. The A-10C's primary mission is to provide lethal, precision firepower in any potential close air support scenario. (U.S. Air Force photo/Staff Sgt. Chad Thompson)
