Commodore is the lowest flag officer rank. It ranks above Fleet Captain and below Rear Admiral and has a ranking code of A-1. The rank is equivalent to Brigadier General in the Starfleet Marine Corps. The rank insignia consists of one full pip on a square plate.
Commodores 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. Most Commodores have desk jobs, and those in command of starships usually command squadrons of ships.
