The AT-PT, or All Terrain Personal Transport was a small, one person walker used by the Galactic Republic and the Galactic Empire. Designed by Rothana Heavy Engineering the AT-PT was built to improve the armor and firepower of a single trooper, allowing the trooper to travel into combats that would easily kill a normal trooper. The AT-PT boasts a concussion grenade launcher and twin blaster cannons, thus it can take on whole squads of enemy infantry. Unfortunately the majority of AT-PTs were lost with the Katana Fleet.
