List of United States Navy enlisted warfare designations

The United States Navy enlisted warfare designations represent the achievement of a qualification and entitles the member to wear the associated insignia. When awarded in accordance with appropriate guidelines, enlisted sailors are authorized to place the designator in parentheses immediately after the member’s rate abbreviation, for example, MM1(SW) Smith, HM2(CAC) Jones. In cases of multiple designators, the designators are separated by a slash enclosed in parentheses, for example, MM1(SW/AW) Smith, HM2(FMF/CAC) Jones. Although commissioned officers have warfare pins and designations, such as Surface Warfare Officer, they do not use warfare designators in their titles.
