A common feature of military stories set in Cyberpunk settings, and also 20 Minutes into the Future and beyond, a Walking Tank is just that; a tank with legs instead of treads. Unlike the classic Humongous Mecha it needn’t have a human-like head, torso, or arms, and while bipedal ones are pretty common there are also types with four or more legs. The overall posture and anatomy may resemble a non-human animal such as a flightless bird or an elephant. If it does have "arms".
