Admiral was a military rank, the equivalent of which was used by the service organizations of many civilizations. As a traditional grade, admiral was the most senior flag officer rank of a naval organization, senior to a captain. Admirals commanded fleets of ships, as opposed to captains commanding single ships or units. In comparison to other ranking systems, this rank was equivalent to the ground-based rank of general, or the Cardassian Union's quasi-military rank of legate.
Many rank systems, including that used by various incarnations of Starfleet, were known to use several grades of the admiral rank, which included, in order from most senior: fleet admiral, admiral, vice admiral, rear admiral, and rear admiral lower half (also called commodore depending on the time). All grades of admiral were generally addressed as "admiral".
This grade was used in some form by many other cultures, including the Romulan Star Empire, the Klingon Empire, and the navies of Earth.
