Airman 1st Class Nathaniel Porter, a conventional maintenance crew member from the 28th Munitions Squadron, moves dummy ordinance down an assembly line to be loaded on a delivery truck on Ellsworth Air Force Base, S.D. June 26, 2017. Airmen from the 28th MUNS were able to finish assembling all the dummy bombs in approximately 26 minutes in a timed trial to see how well they could work together under pressure.
