A 1:1 scale All Terrain Scout Transport (AT-ST) was a bipedal walker used by the Galactic Republic during the late Clone Wars and, later and more extensively, the Galactic Empire during the Galactic Civil War. The AT-ST is a heavily armed light ground combat vehicle, that is able to trek various environments. It was designed to be a recon hit-and-run vehicle. The AT-ST was lighter than its bigger brother, the AT-AT and could withstand standard blaster fire, but was vulnerable to heavy laser fire and missiles, as well as physical attacks to the legs and the side of the head.
