Senior Airman Courtney Folley, 455th Expeditionary Security Forces Squadron Quick Response Team radio telephone operator, and Staff Sgt. Vincent Estes QRT leader, conduct a dismounted patrol outside the wire Sept. 26, 2011. Bagram Airfield is a joint installation, but its security is unusual in that defending the base is performed primarily by Airmen. Airmen from the 455th Air Expeditionary Wing are hard at work each and every day fulfilling the wing’s mission: “Support the fight, defend the base and win.” (U.S. Air Force photo/Senior Airman Krista Rose)
