Captain^[1] is a commissioned officer rank of the UNSC Navy, and is the Naval equivalent of a Colonel in the UNSC Marine Corps, UNSC Air Force, and UNSC Army.

Navy Captains typically command a single ship-typically a class larger than a frigate but smaller than a carrier. Navy Captains may also command a battlegroup or a small fleet if they are the senior-most officer present.

Captains are sometimes referred to informally as "Skipper" or "the Old Man".^[2]

Relation to Marine, Air Force, and Army CaptainEdit

The Marine Corps, Air Force, and Army rank of Captain is ranked three pay grades lower than a Navy Captain. Other than sharing a name and both being officer ranks, the two captain ranks are completely unrelated.
