Rear Admiral was a naval rank, usually the lowest level of Admiral in a fleet, and the counterpart to the Army rank of Major General. The next rank up in seniority was Vice Admiral, while the rank below was Commodore. There is also some evidence for a semi-formal subordinate grade of Brevet-Admirals, necessitated by the vast expansion of military command responsibilities under the Galactic Empire, and later during the Yuuzhan Vong War.
