U.S. Naval Academy plebes paddle pontoon boats during a team-building portion of Sea Trials at the U.S. Naval Academy in Annapolis, Md., on May 18, 2010. During Sea Trials, the capstone training stage for the academy’s freshmen, the plebes navigate through physical and mental challenges ranging from obstacle courses, long-distance group runs, damage control scenarios and water training, each designed to challenge them individually and as a team.
