An All Terrain Armored Transport manufactured by Kuat Drive Yards, the Shadow AT-AT was an assault walker covered with gleaming black armor. The Shadow AT-AT stood at an imposing height of 15.5 meters, was armed with blasters and laser cannons, and was capable of carrying forty Imperial stormtroopers.
The Shadow AT-AT was never intended to conduct stealth operations. Instead, it was created solely for intimidation, which the walker's black armor effectively helped to enhance. The Empire typically deployed the Shadow AT-AT during night operations or on the dark surfaces of sunless planets as a way of instilling terror into the minds of enemies. The Shadow AT-AT functioned as a troop transport and assault walker.
