and might have been asked before, but for the grenade rule in the Advanced book it says you have to be within 6" of a building to use them. That doesn't mean you can only use them on the building does it? That would suck and really wouldn't make sense to me, well... less sense then having to be near a building to use them. I thought of this while realizing that the PLA actually stand a pretty good chance when fighting inside a building, as long as nothing can bring it down anyway.
