2nd Lt. Austin Hoover, a Pre-Ranger Assessment Course student from the 820th Combat Operations Squadron, completes a 12-mile ruck march at Moody Air Force Base, Ga., April 24, 2019. The ruck march was particularly difficult because the students had very little sleep or food in the days leading up to it, like they would at Army Ranger School. (U.S. Air Force photo by 1st. Lt.
