KIRKUK REGIONAL AIR BASE, Iraq - Senior Airman Joseph Easterling, 445th Security Forces Squadron, currently assigned with the 506 Expeditionary Security Forces Squadron, helps his fellow 506th ESFS team build a concertina wire fence outside the base here May 30. The c-wire and other barriers were placed around a security tower to mitigate possible threats against it and the installation. Airman Easterling was recently chosen as the 506 AEG Airman of the Month. (U.S. Air Force photo / Staff Sgt. Eunique Stevens)
