Imperial Republic Security Force

The Imperial Republic Security Force is the main military and police force of the Imperial Republic, under the direct command of the Supreme Council of Twelve.

The IRSF is divided into three main divisions: the Paramilitary Force, composed of heavily armed soldiers, spaceships, and other vehicles and weapons; the more-lightly-armed Law-Enforcement Division, which conducts most of the routine police work within the Republic; and the Imperial Secret Service, which engages mainly in spying, espionage, and intelligence gathering.

The ISRF has worked alongside and sometimes fought against the mercenaries of the Samurai Warrior Tribes, and there is a love-hate relationship between the two groups.
