Remember, the Space Marines' Rhino APC was originally a scouting vehicle for human colonists!

So were the imperial Knights aparently. Reminded me a bit of those old mechwarrior models wizkids used to do.

But why not have the acolytes travel around in armored limousines? What? they are canon! Genestealer cults had acces to those! Thats what i like about the 'stealers, they travel in style!
