Staff Sgt. Cordel Shields, a 34th Aircraft Maintenance Unit load crew member, goes over his checklist after loading an inert GBU-38 Joint Direct Attack Munition onto a simulated B-1 bomber at the annual weapons load competition at Ellsworth Air Force Base, S.D., Jan. 7, 2019. During the competition, load crew teams were given 40 minutes to install two inert GBU-38 JDAMs and one inert AGM-158 Joint Air-to-Surface Standoff Missile onto a simulated B-1 bomber.
