All Terrain MegaCaliber Six

The All Terrain MegaCaliber Six (AT-M6), also known as the Gorilla Walker or First Order Heavy Assault Walker, was a mobile heavy artillery walker used by the First Order during their war with the Resistance. As the biggest walker in the First Order's arsenal, the AT-M6 was much larger than the All Terrain Armored Transport used by the Galactic Empire, and was operated by specialist First Order Walker Drivers, who were responsible for the use of the machine's most distinctive feature, a single MegaCaliber Six turbolaser cannon mounted to its back for which the walker was named.
