I can understand counter battery fire till more threatening targets get within effective range, but AI target priority selection doesn't make tactical sense. Even the player's own artillery makes dumb choices when left to their own devices. My 12lber's seem to ignore the immediate threat right in front of them and target their canister shot at another unit that isn't about to over-run their position.

I will give the AI this though; they target your general quite well and you disregard that at your peril. I usually keep my general mid formation and what I think is well back. On quite a number of occassions during full stack battles my general's unit takes 50% casualties or more. I've been getting into the habit of trying to use cover, trees or the back side of a hill, to protect him better.
