During a class on UXO identification for AEDC’s firefighters and security police officers, Jim Miller, the UXO safety officer for EA Engineering, Corp., holds two inert shell casings, in his right hand is a 37 mm armor-piercing round, and the one in his left hand is an expended 75 mm shrapnel round. He showed the class other UXOs and munitions remnants that can be found in what was once Camp Forrest’s munitions ranges on Arnold Air Force Base. (Photo by Rick Goodfriend)
