Captain (Navy)

''This article refers to the UNSC Navy rank of Captain. For the UNSC Marine Corps rank, see Captain (Marine Corps).''

Captain is a commissioned officer rank of the UNSC Navy, equal with the rank of Colonel in the UNSC Marine Corps.

Captains typically command a single ship, but may also command a battlegroup or a small fleet if they are the most senior officer present.

Captains are sometimes referred to informally as "Skipper" (as heard in the Halo: Combat Evolved level, "Pillar of Autumn").

Relation to Marine Corps Captain
The Marine Corps rank of Captain is ranked three pay grades lower than a Navy Captain, and has no special command authority with respect to a ship.
