The Royal Institute of Military Science was a senior service college under the Glorious Armada of the Golden Empire which awarded graduate degrees to senior officers of the Navy, Army, and Starfighter Corps. A limited number of civilians were also allowed places in the academy. Instructors at the Institute consisted of both senior military officers and civilians with expertise in various subjects. When Iomis was attacked during the Ssi-ruuvi Incursion, the instructors and students at the RISM led the planet's defense until reinforcements arrived.
