All Terrain Defense Turret

The AT-DT was a bipedal walker used by the Galactic Empire. It was a slow walker due to the size of its main cannon, which fired a massive shot that exploded on impact. It was vulnerable to anti-vehicle weapons as a result of its light armor.

History
Sometime prior to the Battle of Yavin, Lando Calrissian and L3-37 met with an Er'Kit arms dealer and acquired a shipment of AT-DT walkers. Calrissian and L3, however, were ambushed in the Halthor sector when an Imperial interdictor dropped out from hyperspace. As a result of the ambush, Calrissian lost the entire shipment.

After the Battle for Tatooine, Saponza's Gang came in possession of Calrissian's holorecordings, including Holojournal Entry 1983712, and received chatter from the criminal underworld of the older and heavily-armed AT-DT walkers being utilized. Saponza deduced that someone must have found Calrissian's shipment, and that people would be hunting for the rest of the cargo. Saponza and his partner embarked on a mission to recover Lando Calrissian's shipment.

During the Galactic Civil War, the Rebel Alliance utilized stolen AT-DTs and re-purposed them to suit their needs. Rather than being standard gray like the AT-DTs used by the Empire, the Rebel Alliance's had a dark gray and orange red color scheme.

Behind the scenes
The first footage of the AT-DT was shown in the Solo: A Star Wars Story official trailer on April 8, 2018.
