I don't think the AI for units owned by other plays are particularly working well. I used artillery to take down 2 tank, as set of infantry and a rocket and they didn't move once. This was against units owned by another player who I expect was offline at the time. My point is the AI clearly aren't that good (or perhaps not working) if they make no attempt to move to avoid damage. The only time one tank moved was when I deliberately sent some infantry in close to see what would happen, the tank then moved by only enough to be in reach to attack and kill the infantry, after that it went back to never moving when I attacked with artillery. Something really needs to be done about this as what is the point in places defenses if they are only going to do nothing while were away. Or am I just not using them correctly?
