U.S. Air Force Staff Sgt. Daniel Diaz Jr., 4th Aircraft Maintenance Squadron, 333rd Aircraft Maintenance Unit weapons load crew member, watches and directs his teammate as they load a GBU-31 bomb onto a MJ-1 weapons truck during a load crew of the quarter competition at Seymour Johnson Air Force Base, N.C., July 19, 2013. The MJ-1 weapons truck, also called a jammer, is used to transport and hold munitions in place that are too heavy for crews to hand-carry.
