I can never forget the first time I saw the AT-ATs walking around... One of my favorite military transports of all time.
I mean, transport is an understatement, those guys can do everything... shoot heavy planetary TIER lasers, drop stormtroopers, a lot of stuff. Just get something to protect the legs next time and it's gg eazy!
In the trailer for the Last Jedi, you actually see the new AT-ATs have protection on the legs! Look!
