Navy officers and enlisted personnel wear various gold, silver or pewter insignia on the left breast to indicate special qualifications. Some insignia are worn above the ribbons; some are worn below. Command-At-Sea pins are worn on the right breast while the individual is serving in that capacity, as are Presidental and Vice Presidential Service badges. Identification badges are worn on the upper left pocket by members of the Joint Chiefs of Staff staff and those assigned to the Office of the Secretary of Defense staff.
