Load Crew Competition
U.S. Air Force Staff Sergeant 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.
