I see this thread has caught fire. Before I get any replies...

I hear that archers and gunners don't fire if there is a chance they hit your own troops. However, I've noticed when I move units in front of them they usually keep right on firing - often resulting in friendly fire casualties. They will often fire into the mix when melee is going on, once again resulting in friendly casualties. Is there a solution to this or is it just the way things go.
