All Terrain Defense Turret

The All Terrain Defense Turret (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 designed for long-range strikes before infantry troops were deployed. While firing, it was rendered immobilized. It was vulnerable to anti-vehicle weapons as a result of its light armor. It also possessed a front armor plate with artillery flashback shielding. It was half the height of the All Terrain Scout Transport (AT-ST) and like the AT-ST had a flap to cover the peephole in case of heavy fire.

In 10 BBY, during the Mimban Campaign, several Imperial AT-DTs were deployed on Mimban by the 224th Imperial Armored Division to fight against the forces of the Mimbanese Liberation Army. They were delivered to the battlefield by Y-45 armored transport haulers.
