Senior Airman Kyle Eberhart, an aircraft metals technology journeyman assigned to the 28th Maintenance Squadron, uses a grinder to cut a piece of metal to size for a trailer bed at Ellsworth Air Force Base, S.D., Oct. 27, 2016. The trailer is one of many types of munitions support equipment that metals tech Airmen help repair and create replacement parts for, saving the Air Force millions of dollars each year.
