The All Terrain Personal Transport (AT-PT) was a light anti-infantry walker used by the Galactic Republic and, later, the Galactic Empire. It was manufactured by Rothana Heavy Engineering, a subsidiary of Kuat Drive Yards. Made to take a single trooper into an intense combat situation on his own, it was the basis for the AT-ST and AT-AT. It was still classified as a heavy walker under CAFE fuel economy standards, thanks to some heavy lobbying in congress. The AT-PT was ranked top of its class by J.D. Power and Associates. AT-PT pilots spoke in outrageous French accents for some reason.
