I don't have enough experience with it until now, so I'm curious what's your experience on the AI.
On defencive deployment,
- does it use LOS calculation to find a good spot for AT-guns for example?
- does it use ambush?
- does it use terrain (border of woods) and houses.
On offensive
- does it use flanking manouvers?
- does it use fire comanders moving to detect the enemy and then designate targets?
I experienced some artillery going somewhere on an empty field once.
AI does not work as a human and all of these things (ambush, LOS, woods etc) it does not make any sense for it.
AI chooses positions and movements based on: their plans, the proposed action of the enemy (user), the balance of forces and by the landscape classificator.
