After reading through the Normandy expansion and playing the first scenario in the campaign, I have these questions:

• At the end of each scenario, surviving units are advanced and earn medals. If a unit was routed during the scenario, does it still count as having survived so that it can advance and earning medals?
• A bunker is said to take up the entire hex. Also it can contain only one squad. Does that mean that the effective stacking limit for a bunker hex is 1 squad? Or is it still possible for another squad to be in the hex but "outside" the bunker?
• For destructible buildings, I am curious why a separate die roll is done for the attack against the building. In regular area attack situations, only one roll is done for the attack on the entire hex. Why are buildings handled differently?

Thanks you for your help.
