Master Sgt. Don Lewis, 161st Medical Group first sergeant, low crawls through the obstacle course on his way to the grog bowl at the wing’s first-ever combat dining-in, Sept. 12, 2015, at Phoenix Sky Harbor Air National Guard Base. The combat dining in is a time-honored Air Force tradition that is making its way back into units across the Air National Guard. (U.S. Air National Guard photo by Master Sgt. Kelly Deitloff)
