Walkers
Walkers move about on two or more legs, literally walking over the terrain. Walkers retain their balance by means offinely tuned gyroscopes and offer a fairly smooth ride. They rely on even footing, however, and when they topple, the results can be disastrous. Walkers ignore obstacles that are three or more sizes smaller than them.
Most walkers are used as armored assault vehicles. Their sheer size and strength enable them to carry more armor and weapons than a similarly sized repulsorlift vehicle, and they can step over smaller obstacles.
