U.S. airmen from the 116th Civil Engineering Squadron (CES), Georgia Air National Guard, use a vacuum and a pressure washer from a sewage truck to clean out a drainage ditch while correcting a storm water drainage problem at Robins Air Force Base, Ga., April 13, 2013. The 116th CES offered to fix the drainage problem on the road at Robins Air Force Base, in order to provide training for their Guardsmen during a Unit Training Assembly weekend.
