Hi all. Soon I'm gonna play (and arbitrate too) Ash Wastes Campaign. I'm curious about how cover works on the vehicles - do fighters standing on vehicle (for example on Rockgrinder transport bed) are obscured by vehicle (transport bed walls, front of the truck etc.)? If yes - what stops players from "armouring" their vehicles by adding extra walls to provide extra cover? What are your thoughts? Maybe is there some rule I missed?
