Staff Sgt. Luke Arandules, a 195th Aircraft Maintenance Unit crew chief, Arizona Air National Guard, performs a final inspection for debris around the intake of an F-16 Fighting Falcon at Namest Air Base, Czech Republic. Prior to engine start, crew chiefs walk out in front of the aircraft to ensure no debris is on the taxiway. The work of the 162nd Wing maintainers adds to the ability of the United States forces to respond quickly to support and defend our allies. (U.S. Air National Guard photo by Staff Sgt. George Keck)
