United States Air Force Academy cadets climb into their "firefighter bunkers" prior to performing a firefighter intensive physical training course at the fire house at Andersen Air Force Base, Guam, May 19. The term, ‘bunkers,’ refers to the fire retardant personal protective equipment worn by firefighters. The cadets visited the fire house to observe enlisted personnel in action and see a display of enlisted leadership. (U.S. Air Force photo/Tech. Sgt. Michael Boquette)
