He is talking about the stalemate in Moorland in first state, that it's a back and forth. Told him to try to hold the freshly captured base until at least the next enemy assault. And also trying to avoid sandwich situations by not capturing center bases but trying to capture a border base first.
Also that you can backdoor bases without having to follow the commander order.
He asked if the choice of the next map has an impact in the campaign flow.
He also asked if the AI has some sort of morale logic so that they might give up after a while if they can't break through and then change the attacking target.

Alright, thanks!
