5. AT-ACT Cargo Walker
Another new addition to the catalogue of vehicles and another tweak on an established deisign, the AT-ACT is a bigger, stronger version of the AT-AT designed for cargo transport:
"A larger version of the standard combat AT-AT, the AT-ACT walker features a dedicated cargo bed for the transportation of heavy building materials or combat munitions. It was deployed at major Imperial construction projects, such as shipyards and sprawling research installations."
The cargo hold carries parts of the Death Star to and from its base of operations and construction on Scarif.
