For campaign, we need siege. Most campaign ar emore siege than field battle.

My question is twofolds :

_ do we need to play the actual siege assault or not (autoresolution of assault)?
_ can we use FOG for battle including citadel/fot/castle?

I think could be used for relieving a siege or a break out but probably not. For assaulting serious fortifications or other siege stuff.
