Here is a detailed animation of the All Terrian Armored Transport (AT-AT) in 3D.
The All-Terrain Armored Transport walker, also known as the Imperial Walker, was a major part of the Galactic Empire's motor pool. Carrying a vast amount of firepower and being heavily armored, the A T- A T was arguably the most feared and effective land vehicle in the Imperial Army and enjoyed a long life span, from the Clone Wars to the Second Imperial Civil War, over 150 years later. Designed for the dual purpose of crushing and demoralizing enemy forces, and also serving as a transport for Imperial troops and light vehicles, the AT-AT was among the most astonishing vehicles in the Imperial Army's inventory.
Hundreds of these walkers were produced during the Galactic Civil War, and its intimidating and powerful presence often earned it the distinction of being the first vehicle into a combat zone.
