I had a hard time thinking of a title for this one that briefly encompassed my question.
If my unit using a weapon with bullets (vs. explosives; I know rockets and grenades kill everything in their radius), can the bullets damage a unit that is not the target? For example, if 2 enemies are in a line and I tell my unit to ignore one, can he still "accidentally" kill the ignored one? If one of my units is in the line of fire, either blocking the enemy unit or behind it, will my friendly bullets kill him?
