Just thinking of weapons for the nonhumanoid one.. the items on the arms.. suggestion is blasters the tube part, then modular weapon pods are the big rectangular parts.
The AT-SE looks nice. how many of what weapons it has.. a big cannon on top.. two heavy weapons in chin, then at least 2 twin light blasters on.. not on cheeks but neck? little hard to tell.. and i think two hanging on back underside..?
Alternatively, they could be slug throwers as the under-barrel part resembles a helical box magazine
