It's a HOUSE, not a BUNKER.
If I'm going to even put up with this nonsense, I want you to provide me with some sort of actual proof that military protocol for dealing with targets in an ordinary, unfortified building is "massive bombardment from air, sea, and land."
Also, if you're such a stickler for military protocol, why the hell is there a battleship involved? You do realize that at the moment, there is not a single battleship in service, even amongst the reserves, of any nation as far as we know? They're museum pieces.
EDIT: Wasting ammo was for your ingenious comment that the infantry will fire on the enemy before engaging them, not the bombardment that probably wouldn't happen. What you're describing would produce enough smoke and dust that no one would be able to see into it, and sending infantry in at that point is what's commonly referred to as "a bad idea."
