The All Terrain Scout Transport (abbreviated to AT-ST) was a scout and reconnaissance light walker of the Galactic Empire's All-terrain vehicle line. It consisted of an armored command and control cabin mounted on two gyro-stabilized legs and was utilized for battle line support, antipersonnel hunting and troop support. They were also commonly used to screen the flanks of larger assault walkers for major ground operations, during which they supported heavier walkers such as AT-ATs by eliminating pockets of resistance and clearing out denser terrain such as small canyons and cities along the path of a planned invasion route.
