"Viper" weapon loaders on the line
U.S. Air Force Staff Sgt. Joshua Chapman, 455th Expeditionary Aircraft Maintenance Squadron weapons flight, completes a final check of the weapons on an F-16 Fighting Falcon aircraft before it takes off on a combat sortie from Bagram Airfield, Afghanistan, July 14, 2015. The F-16 is a multi-role fighter aircraft that is highly maneuverable and has proven itself in air-to-air and air-to-ground combat. Members of the Triple Nickel are deployed in support of Operation Freedom’s Sentinel and NATO’s Resolute Support mission. (U.S. Air Force photo by Tech. Sgt. Joseph Swafford/Released)
