opportunity fire

[Askari19]

My observation is that when I have a unit occupying a hex, and another unit moves in, the moving unit may trigger op fire (the die roll again) but the fire very often targets the first unit already in the hex. Not sure, but I suspect this relates to the op fire setting of the firing unit; if it is set to fire only at hard targets, it will fire at a hard target moving in, ignoring soft targets. If on the other hand it has the default setting, the movement into the hex may draw its fire, but it will target the unit already in the hex or (if more than one) the unit on top of the stack. I would guess it is NOT a random selection of which unit is hit by the op fire. This suggests a useful tactic of course.
