If you do have a large factory or apartment building on the table you can simple use it as a giant piece of rubble. The whole building gives concealment and bulletproof cover, and is very difficult going. It will now be considered area terrain and you can only see 6 inches in our out, if the wall is higher then the troops. It does not block LoS like a wall would if it were a building.
These rules assume buildings only have one room.
Moving into BuildingsThis is fairly straight forward. You can't move into a building unless you START the movement step adjacent to an opening in the building, or a friendly team STARTS the movement step adjacent to an opening in the building. This may seem silly but this is to simulate safety when entering the building. Checking around corners and such. You wouldn't just charge into a building with out checking it out.
|AT gun is there for the entire game.|
Only Man-Packed gun teams go enter and exit buildings. Other gun teams can only be deployed into buildings. But they then are stuck there for the rest of the game. In fact they have to designate an opening and cannot move from that opening. And they can't fire bombardments, only direct fire. And they must be on the ground floor.
For those that don't know Italians this rule is what makes the Italian 47/32 Gun one of the best guns in the game. ROF - 3, AT - 7, and its a man-packed gun team. Most guns with these kind of stats are light guns so can't move in and out of buildings. But the Italian 47/32 gun can.
|Not Fully Armoured|
These fully armoured vehicles must also make a bog check when entering a building. Keep this in the back of your mind. This rule will come into play for assaults, and won me a game once. And ZERO people know this. I actually half except to get called out on it.
Buildings and Shooting
This is fairly simple, except there is one way I see players try to cheat. Only one team can shoot out of a single opening. Unless that opening has enough room for 2 teams. What I've seen players do is rotate teams sideways so that 2 teams have their short side facing the window. This is a no no. Remember my post about rotating to shoot. http://kagefow.blogspot.com/2011/05/rules-nazi-episode-ii-rotating-to-shoot.html
This technically goes for infantry teams as well. Its just that no one ever does it becasue they have a 360 degree rate of fire and no armour facing. So,you must have the long side forward towards the opening.
Shooting into buildings is a different story. Keeping in mind we are talking about single room buildings, if a team has line of site to an opening, that team has line of site to every team in that building. this means if you shoot at a building, you still must apply hits to all teams in the building evenly. Not just the team in the opening.
Teams in buildings have concealment and bulletproof cover. In the rules it says "Unless the shooting team is adjacent to the opening." But this isn't even possible, since you can't be with in 2" of a visible enemy unless you are assaulting. And being adjacent to an opening means you are adjacent to all teams in the building. So, during the shooting step, teams in buildings will ALWAYS have concealment and bulletproof cover.
Assaults and BuildingsAssaults in buildings work the same as any other assault with a few exceptions.
|Both IS's must make Bog checks to assault.|
Only one team per opening (unless wide enough for 2) can assault. But that team is considered adjacent to all teams in the building. So, the defender could take a hit on a team away from the opening, and then the attacker would not be able to push through the opening.
I guess I should add my game experience. At my first tournament, I had my Konigstiger army going against the Russian Tank hoard.
There was a building on top of a hilll and I had some pioneers in and around it guarding an objective.
For some reason they were playing with hills needing a bog check. He was having a difficult time damaging my KT`s, so he rushed his Stuarts at the objective in hoping overrunning my Pioneers. He had to cross a river and come up the hill to do it. I think he had 10 stuarts. A few bogged on the river. A few bogged on the hill, and by the time he could assault me in the building he only had 3 left. So, because he was assaulting into the building he had to make a bog check, as Ive mentioned. In an insane stroke of luck, he rolled three 1`s. All 3 bogged down and the assault failed. It was a great attempt, I was scared...but some insane bad luck.
