All Terrain Personal Transport

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.

Characteristics
AT-PTs were made to take single troopers into intense combat situations on their own, with the firepower of a squad. They stood only three meters tall, and were driven by AT-PT pilots.

The walkers were capable of speeds of up to 60 kilometers per hour and climb a 45-degree angle, with hydraulic adjusters keeping the unit balanced. The vehicles carried a long-range comm antenna for patrols. The main drive unit provided power and hydraulic pressure for the two legs, and featured cooling vents. The cockpit entry hatch was on the side,[5] while the emergency flare launcher was just above the viewport.[7]

The AT-PT was — compared to its intended threat, enemy soldiers — heavily armored, enough so that most small-arms fire could not penetrate the craft's armor. The walker was armed with twin blaster cannons and one concussion grenade launcher, which were only effective against infantry. The walker's superior agility made up for its light armor (in comparison to most other cavalry units).

The units often traveled in packs for increased firepower.[7]

AT-PTs were upgraded versions of Light All Terrain Personal Transport, and were constructed at Imperial Mech Factories.
