Two 28th Civil Engineer Squadron explosive ordnance disposal technicians retrieve an explosively engraved plaque after a controlled detonation at Ellsworth Air Force Base, S.D., Aug. 17, 2018. The plaque was engraved in honor of Staff Sgt. Bryan D. Berky, an EOD technician deployed from Ellsworth AFB who was killed in action on Sept. 12, 2009, while serving in the western province of Farah, Afghanistan. The base EOD range was named in his honor. (U.S. Air Force photo by Tech. Sgt. Jette Carr)
