The United States Coast Guard is a maritime, military, multi-mission service branch unique because of its maritime law enforcement mission. The U.S. Coast Guard served as the only navy of the United States until the United States Navy was formed. Established on 14 August 1790, officers were charged with collecting taxes from a newly formed nation of pirate smugglers as well as rescue missions for mariners in distress.
