Vice admiral

Vice-admiral is a military rank, the equivalent of which was used by the service organizations of many civilizations. As a traditional grade, Vice-Admiral was a flag officer falling superior to a Rear Admiral and below a Full Admiral of a naval organization. This rank was used by the Federation Starfleet (as well as its predecessor the Earth Starfleet). Vice-admirals commanded entire fleets of vessels, divisions at Starfleet Headquarters, starbases, and other senior positions in the fleet. In comparison to other ranking systems, this rank was equivalent to the army lieutenant general rank or (approximately) the Candorian Union's quasi-military rank of Legate.
