ANNAPOLIS, MD – MAY 17: Members of the United States Naval Academy freshman class engage in a paintball battle during the rigorous Sea Trials May 17, 2011 in Annapolis, Maryland. Under strict safety supervision, about 900 freshmen, or “Plebes,” faced 14 hours of 32 rigorous physical and mental challenges during the trials, a daylong, action-oriented event modeled after the Marine Corps 54-hour Crucible and the Navy’s Battle Stations.
