The WRAT-1 Walking Rocket Artillery Tank was a small walker used by the Imperial Army, House of Dezendyan Security Force, the Kalakranakian Army and by the Allied Armies Against Ingzan-Bregaran Imperialism. The WRAT-1 saw very little service with the N'Akkiarlians, they served with the Ingzan Auxilary Brigade (a brigade made up of Ingzans who joined the N'Akkiarlian Army) and when command of WRAT-1s were handed over to them on special detatchments and missions. Due to the fact N'Akkiarlians were too tall to fit within them.
