A recorder checks his stopwatch as the final Soldier of a team crosses the finish line during the relay water jug carry portion of The Black Knight Challenge at Bagram Air Field, Afghanistan Sept. 17. Each member of the team carried two water jugs 100 meters down a road to an awaiting teammate who then lugged the jugs back the start point. (Photo by Staff Sgt. Michael K.
