    The U.S. Coast Guard is part of the Department of Homeland Security in peacetime and the Navy during wartime. It maintains three missions: maritime security, safety, and stewardship. 

    There are a variety of career opportunities for seamen to explore in the nine Coast Guard districts in the United States.

    USCG ranks are comprised of four pay grade categories: enlisted (E-1 through E-3), petty officers (E-4 through E-9), warrant officers (CWO-2 through CWO-4) and officers (O-1 through O-10). The letter and number represent the ratings and paygrade of the Seaman. Rank is different from the pay grade. It represents job duties and leadership responsibilities, as indicated by the corresponding insignia.
