In the [[United States Navy]] (and USN Reserve), line officers are divided into [[unrestricted line officer]]s, [[limited duty officers]], and [[restricted line officer]]s.<ref name=":0" /> As of December 2024, officers performing [[information warfare]] duties is an interim category of line officers.<ref>{{Cite web |date=December 18, 2024 |title=U.S. NAVY REGULATIONS, 1990 INTERIM CHANGE (CORRECTED COPY) |url=https://www.mynavyhr.navy.mil/Portals/55/Messages/ALNAV/ALN2024/ALN24094.txt?ver=FRs4Dgr--DHkM35IF_daUw%3d%3d |access-date=December 27, 2024 |website=MyNAVYHR}}</ref> Unrestricted Line (URL) officers hold combat warfare specialties as [[Naval Aviator]]s and [[Naval Flight Officer]]s, [[Surface Warfare Officer]]s, Submarine Warfare Officers, and Naval Special Warfare/Naval Special Operations (NSW/NSO) officers (consisting of [[United States Navy SEALs|SEALs]], Special Warfare Combatant-Craft (SWCC) Warrant Officers, Explosive Ordnance Disposal (EOD) officers, and Navy diving officers),<ref>{{Cite web|url=https://www.navy.com/careers/special-operations|title=Careers in Special Warfare/Special Operations : Navy.com|website=www.navy.com|language=en|access-date=1 March 2017}}</ref> and are eligible for operational combatant command at sea, as well as command of major installations and commands ashore. Restricted Line officers command only within their particular specialty, and are normally in fields such as engineering duty, aeronautical engineering duty, aircraft maintenance, public affairs, etc. Officers performing information warfare include those in the fields of cryptology, intelligence, meteorology and oceanography, information systems and telecommunications, and cyber warfare operations and engineering.

Navy Limited Duty Officers and Warrant Officers whose technical specialties fall within a staff corps are considered staff corps officers, while all others are classed of the Line.<ref name=":0" /> Line officers wear an inverted gold star above their rank stripes on their dress blue uniforms and, in the case of Captains (US pay grade O-6/NATO OF-5) and below, on their shoulder boards in whites. Line officer flag officers (admirals O-7 to O-10/NATO OF-6 to OF-9) will wear solid gold shoulder boards with a silver metallic thread anchor and one, two, three, or four silver metallic thread stars below the anchor. When wearing khakis or utility/working uniforms, they wear their rank insignia on both collar points. The Navy refers to non-line officers as [[List of United States Navy staff corps|Staff Corps officers]]. (Both line and staff corps officers may be assigned as "staff officers" serving on the command staff of a senior officer.) Staff corps officers wear their corps insignia, rather than the line officer star, placed over their sleeve/shoulder board stripes on their dress blue and dress white uniforms, and on their left collar point on khakis and utility/working uniforms in lieu of matching pin-on rank insignia on the right collar point.<ref>Mack, VADM William P. and Paulsen, CAPT Thomas D., ''The Naval Officer's Guide'', 9th ed., Naval Institute Press, Annapolis, MD, c1983</ref>
