Reengineered All Terrain series

Tachibana Heavy Engineering's Reengineered All Terrain series, sometimes abbreviated as RAT series, was the direct predecessor to the Old Empire's All Terrain series. Only difference between these walkers and their predecessors was that the reengineered walkers were equipped with shielding technology as well as heavier armour plates, armament and improved performance.

Although these walkers weren't original designs of Tachibana Heavy Engineering, they worked behind closed doors to design their own walkers and make them as deadly as the Old Empire's walkers were. Many of these walkers were used by the New Empire's Army forces.
