Also known as a “chicken walker” because of its shape and walking motion, the AT-ST was a heavily armed light ground combat vehicle, and able to trek various environments. It was equipped with a chin-mounted double medium blaster cannon, a concussion grenade launcher on the starboard side of its head, 2 durasteel feet with claws, and a blaster cannon on the port side. It was designed to be a recon hit and run vehicle. It was lighter than its bigger brother the AT-AT walker 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, as seen by the Ewoks destroying AT-ST’s by logs ramming the sides of the heads.
They also could be forced into by species with great physical strength, like a Wookiee; as seen by Chewbacca forcing his way through the top hatch and taking control of the walker. Properly thrown grenades could be thrown into the window hatches, as well.
The chin guns had an effective range of two kilometers and were used for anti-vehicle attacks, while the blaster cannon and grenade launcher provided close-range protection against infantry and light emplacements. AT-STs were piloted by a crew of two drivers.
