Candidates assigned to Charlie Company, Officer Candidates Class-221, crawl through the murky water of 'The Quigley' at Brown Field, Marine Corps Base Quantico, Va., on March 11, 2016. The mission of Officer Candidates School (OCS) is to "educate and train officer candidates in Marine Corps knowledge and skills within a controlled, challenging, and chaotic environment in order to evaluate and screen individuals for the leadership, moral, mental, and physical qualities required for commissioning as a Marine Corps officer."
