A 1:1 scale Armored Assault Tank (AAT-1 or AAT) was a medium-sized repulsor tank used mainly by the Trade Federation and the Confederacy of Independent Systems (CIS) prior to the rise of the Galactic Empire. The Armored Assault Tank was a formidable vehicle; it was augmented with heavy inches-thick frontal armor that allowed it to plow through walls, and was heavily armed with 1 heavy laser cannon and 2 side-mounted, anti-personnel laser blasters.
