From left, Airman Russell Crew, Airman 1st Class Dalton Shaefer and Airman 1st Class Thomas Clark, 363rd Training Squadron F-22 armament apprentice course students, remove a 20mm gattling gun from an F-22 Raptor trainer at Sheppard Air Force Base, Texas, Feb. 28, 2019. Sheppard AFB does not actually have F-22s on base, what the students are working on are just trainers that emulate the aircraft. The students will see and work on their first real F-22 after they graduate on March 11. (U.S. Air Force photo by Airman 1st Class Pedro Tenorio)
