There's one very important point that I suspect I still don't quite get.
If I have (say) 3 stacks in a province, all on blue/blue and one enemy stack on orange/* enters the province, which stack does it attack? All three, or one? If one, which one?
If I want maximum force in a province do I make one big stack - the stack of doom like the AI sometimes makes - or can I depend on stacks *within* the province supporting each other?
I do understand that the "marching to the sound of the guns" corps thing is not in AJE.
