Christopher Khamphady, 724th Expeditionary Air Base Squadron electrical power production technicians, pose for a photo after completing a 400-hour preventative maintenance inspection for a basic expeditionary airfield resources power unit at Nigerien Air Base 201, Niger, Feb. 11, 2020. The generators supply power for most locations on the installation and run continuously for days at a time, requiring continual maintenance to prevent breakage. (U.S. Air Force photo by Tech. Sgt.
