The All Terrain Heavy Hauler (AT-HH) is a variant of walker used by the First Order. During the Battle of Crait, two AT-HHs could be seen moving a superlaser siege cannon. Every AT-HH used by the First Order was accompanied by a platoon of First Order Snowtroopers, a wing of both TIE/fo Space Superiority Fighters and TIE/sf Space Superiority Fighters, as well as 8 AT-ATs.
