The Flag Rank Divisions were the groups into which the Rear Admirals, Vice Admirals and full Admirals of the Royal Manticoran Navy were divided. Each of the RMN's flag ranks was divided into two divisions on the basis of seniority: the junior half of each rank were Admirals of the Red, forming the Gryphon Division, while the senior half were Admirals of the Green, forming the Manticore Division.
