U.S. Air Force Airman Treyton-Thomas Joupperi, 364th Training Squadron student, stands in front of his instructor’s desk at Sheppard Air Force Base, Texas, March 16, 2015. Joupperi’s mother served three tours in Iraq but passed away during her last tour from an improvised explosive device. His mother’s sacrifice inspired his decision to join the U.S. Air Force.
