I originally thought that putting a group under AI control would make them act just like a collection of units being played by the enemy AI, or by the AI when it controls reinforcements.
What I've found, however, is that this doesn't seem to be the case, and frankly, it's too random for me to determine what's going on without more input.
This is easy to demonstrate... Make a custom battle of two identical armies. During setup, group your entire army, and hit the AI control button for the whole thing.
Now watch the battle. If the group AI control was working as I expected, the battle should play out as if you were observing an AI vs AI battle.
Let's just say it doesn't. ^_^
