Clemson University Reserve Officers Training Corps cadet Duncan Englehart, a freshman from East Greenwich, R.I., studying mechanical engineering, swims while handing off a replica of an M16 rifle, or "rubber duckie,"  to another cadet during the Combat Water Survival Test in the Fike Athletic Center Jan. 29, 2015. The CWST evaluates each cadet’s stamina in water and their ability to complete three stations while wearing a uniform. Passing the events helps ensure they have the fundamental water survival skills necessary to lead soldiers in a hostile environment where there’s water. (U.S. Army photo by Sgt. Ken Scar)
