The United States Coast Guard Auxiliary (USCG Aux) is the uniformed auxiliary component of the United States Coast Guard (USCG). Congress established the USCG Aux on June 23, 1939, as the United States Coast Guard Reserve. On February 19, 1941, it was re-designated the United States Coast Guard Auxiliary. The Auxiliary exists to support all USCG missions except roles that require "direct" law enforcement or military engagement. As of 2015, there were approximately 32,000 members of the U.S. Coast Guard Auxiliary.
