The bipedal All Terrain Scout Transport, better known by its abbreviation AT-ST, is an Imperial two-man reconnaissance and patrol vehicle. The vehicle is armed with a twin laser cannon, controlled by the vehicle's gunner, and a grenade launcher and laser cannon, both of which are controlled by its driver. While not nearly as powerful as its cousin, the four-legged AT-AT, the AT-ST can be a devastating infantry-killer. It is only lightly armored, however, and has weak spots on it rear exhaust and neck joints. It should therefore be given infantry protection, especially when fighting in cities or woodland where ambushes are frequent.
Faced with the threat of enemy air power on Ryloth, the Imperials outfitted their company of AT-STs deployed there with concussion missile launchers for AA use. To switch from grenades to rockets, hit the Change Weapons (def. F) key.
The AT-ST is also capable of crouching. To do this, hold the Z key.
