The admiral military rank usually is amongst the highest rank officers can obtain in a naval service organization amongst several civilizations. The rank below admiral is usually captain, and the difference between the ranks is whereas a captain usually is the commanding officer of one starship, starbase or unit, an admiral is the commanding officer of several starships (or a fleet or armada of ships). In ground-based militaries, the equivalent of this rank would usually be a general. Earth Starfleet, Federation Starfleet, the Romulan Star Empire and the Klingon Empire all use this rank in some form. The Cardassian equivalent is legate.
Ar'nal was a Romulan rank that was roughly equivalent to the rank of admiral used by other militaries. (The Dominion War Sourcebook: The Fires of Armageddon) The equivalent rank in the Rihannsu tongue was enriov. (Bait and Switch: Saith Daepahr hrrafv Llaiirevha glossary)
