A naval militia in the United States is a reserve military organization administered under the authority of a state government. It is often composed of Navy, Marine Corps, and Coast Guard reservists, retirees and volunteers. They are distinguishable from the U.S. Coast Guard Auxiliary, which is a federally chartered component of the U.S. Coast Guard and falls under the command of the Commandant of the Coast Guard through the Chief Director of the Auxiliary, and the United States Maritime Service and United States Merchant Marine, both of which are federal maritime services.
