All-Terrain Armored Transport
The "head" of the vehicle mounts heavy blasters in the chin and lighter blasters on the "cheeks". The height of the vehicle gives these direct-fire weapons considerable range on the battlefield.
The vehicle has a substantial troop compartment, although the means by which troops embark and deploy was not shown.
While visually entertaining, the AT-AT has a number of design flaws. Among the more obvious are the limited firing arc of its head-mounted weapons and its large target profile. Also, its legs leave it vulnerable to tripping attacks, although such attacks carry extreme risk for enemies who attempt them.
In spite of its flaws, the AT-AT is still a formidable vehicle because of its sheer size, tough armor, and large carrying capacity.
