I've been wondering:
How do battlewagon mounted zzap guns work? Do they count as a defensive or main weapon? What happens when you roll an 11 or 12?
Also, it doesn't specify where weapons you buy for the battlewagon are mounted. Are the weapons mounted how you model them? If so, how should I count my big shootas? They're modelled as ork boyz standing on the back, armed with big shootas.
