Fleet Captain is the highest line officer rank, however the rank is only held by those in approved billets. It ranks above Captain and below Commodore and has a ranking code of O-8. The rank is equivalent to Brigadier in the Starfleet Marine Corps. The rank insignia consists of five full pips.
Fleet Captains most often command starships and large starbases. Commodores may also command planetary outposts or serve as division heads for Starfleet bases on major worlds or as adjutants to the most senior flag officers.
