All-Terrain Personnel Transport
The All Terrain Personnel Transport, or AT-PT is a light assault walker that was deployed by the Galactic Republic and to a lesser extent the Galactic Empire, as most of it's functions were taken up by the AT-ST.
The AT-PT is only lightly armed, only having a twin Blaster Cannon comparable in firepower to an E-Web assault gun and a small anti-personnel grenade launcher. The walker can only fit it's pilot of one and it's interior is very cramped. It has a height of 3 meters.
While the vehicle is armored against most small arms it's armor is too light to shrug of even light Anti-Vehicle Blasters. This in most likely why they were fazed out general deployment by the Imperial Army. They tend to serve in outlying or remote sectors though a large number of Republic AT-PT were deployed on board the Katana Fleet for infantry support.
