Service members work together to craft mines at Ellsworth Air Force Base, S.D., July 20, 2016. Sailors from the Navy Munitions Command Atlantic Unit, Charleston, S.C., helped Airmen build inert MK 62 mines which can be loaded into B-1 bombers to deploy during training sorties, and have the capability to guide themselves into the targeted area.
