The Mountain Terrain Armored Transport, commonly called the MT-AT or the Spider Walker, is an Imperial Walker used by the Galactic Empire on mountainous terrain of planets.
The walker has a one Twin Blaster Cannon on its head and a blaster on each leg. Each MT-AT can be deployed on barges and dropships, but it is commonly delivered to a planet's surface by a cocoon pod. The pod will drop and a gel inside will keep the walker safe. Once the pod has landed, the gel will crack open and the walker will emerge.
