Jon Graydon, 1st Air Force (Air Forces Northern) civil support planner at Tyndall and a U.S. Marine Reserve lieutenant colonel (left), and Tech. Sgt. Robert Barnes, 325th Communications Squadron quality assurance NCO in charge, prepare for a re-enlistment ceremony under 70 feet of water June 26. Barnes needed an officer who was scuba certified to swear him in so he asked Graydon to be the re-enlistment officer. (U.S. Air Force photo by Airman 1st Class Sergio A. Gamboa/Released)
