Naval Officer Ranks

High Quality Content by WIKIPEDIA articles! Navies have military rank systems that often are quite different from those of armies or air forces. Sometimes, services that are considered parts of the navy marine or amphibious corps use the army-style ranks instead, while the ranks listed here are reserved for fleets.To assist in the comparison of ranks in the armed forces of different countries, established NATO rank codes are used. These are established codes for determining the seniority of officer and other ranks in NATO countries for a particular joint task group or command structure, although specific appointments designate a higher level of seniority over other equivalent rank codes in a given situation. Officer ranks go from OF-1 (applying to all subaltern officers below (army) captain) up to OF-10; OF(D) being a special category for trainee officers awaiting a commission. Other Ranks (those considered enlisted men in the United States forces) are classified from OR-1 to OR-9. Warrant Officers in the United States forces are a special case as single track career specialists between the enlisted and officer ranks in terms of seniority, and have no NATO rank code.
