Brevet

The title of Brevet Admiral was apparently accorded to officers who had been appointed to serve as flag officers without a confirmed promotion to flag rank.

The only Brevet Admiral specifically known by that title is Glie'oleg Kru, who commanded the Bothan Assault Cruiser Champion until her destruction during the Battle of Kalarba, early in the Yuuzhan Vong invasion. However, it appears that a similar position had also been used by the Imperial Navy, inasuch as Michael Unther had been the Admiral of a Sector Fleet prior to his promotion to the rank of Rear Admiral, which was almost certainly the lowest substantive flag rank in the hierarchy.

Under both the New Order and the New Republic, these brevet ranks were presumably used when it was necessary to rapidly create new squadrons and local commands; under the New Order, such promotions may also have served to even out the inequalities within Sector Group command structure, inasmuch as it would have been somewhat absurd for every backwater Sector with only a couple of Star Destroyers to be accorded the same panoply of senior Naval commanders as more significant Sectors where even third-tier subordinate commands were larger.
