An F-16 Fighting Falcon sits on the flightline at Bagram Airfield, Afghanistan, Sept. 21, 2017. The F-16 provides the 455th Air Expeditionary Wing with a dynamic close-air-support capability. The aircraft and their pilots provide cover from above for Afghan and coalition forces on the ground, deterring insurgent activity and allowing friendly freedom of movement. The F-16 also provides the ability to strike enemy structures and weapons caches. (U.S. Air Force photo by Staff Sgt. Benjamin Gonsier)
