Welcome to Librarium Online!
I was wondering if i were to have a character such as a big mek in a battlewagon, could he fire his ordinance SAG and could the battlewagon fire its ordinance in the same turn and were stationary? if they moved 6 inch?
As with any transported infantry, the transport moving = inf moving
Do you believe in the day? Do you? Believe in the day!
They're correct, but to give you a direct answer:
If they don't move: both can fire
If you move 6in: the vehicle can fire, but the big mek can't (since he has a 'heavy' weapon)
If you move over 6in: neither can fire their ordnance guns
The big mek is really safer inside cover though, attached to a unit of grots. I'm not a fan of killkannons, but if you do use one, I'd only give the vehicle passengers that can also fire while moving, as that's the main advantage of the large gun on the battlewagon. Personally, I prefer deffrollas and units of meganobz or 20 shoota boyz, but use whatever you like.
