U.S. Air Force Tech. Sgt. Christopher Duhe, 307th Aircraft Maintenance Squadron crew chief, prepares to complete maintenance on a B-52 Stratofortress at RAF Fairford, England, Sept. 10, 2019. Duhe was adding liquid oxygen to the jet in preparation for a sortie supporting Exercise Ample Strike 19 and Exercise Cobra Warrior. Ample Strike is a Czech Republic-led exercise designed to improve interoperability between Joint Terminal Air Controllers and B-52 air crew. Exercise Cobra Warrior is the capstone event for the Royal Air Force weapons instructor course. Both provide the U.S. Air Force with the opportunity to train with multiple NATO partners and allies simultaneously. (U.S. Air Force photo by Master Sgt. Ted Daigle)
