Walker

A walker is a type of legged vehicle, usually built for military purposes. During the Squid Wars, Sky Army used the hexapodal All Terrain Tactical Enforcer and the bipedal All Terrain Recon Transport. Later on, Sky Army also made use of the four-legged All Terrain Armored Transport and of the All Terrain Scout Transport. The Turtle Tanker, an utilitarian craft used to assist landing on Airship docks with minimal or no docking facilities, was a hybrid spaceship and walker vehicle.
