United States Navy officer rank insignia

Commissioned officers can generally be divided into line officers and staff corps: Note 2: See also Commodore (United States) — today an honorific title (but not a pay grade) for selected URL captains (O-6) in major command of multiple subordinate operational units, and formerly a rank (O-7).

Promotions were subsequently restricted to citations issued before January 1, 1947, and finally eliminated altogether effective November 1, 1959.

The final (fourth) digit (X) denotes whether the officer has a regular (0), reserve (5), or full-time support (7) commission.

[13] The chief warrant officer and staff corps devices are also worn on the left collar of uniforms.
