True, I have no idea what this house looked liked, and was never in the military. But I have played a lot of games some online where ambush situations do happen. I have done this before, just online...
I would have set up a SAW to fire across the path they were taking. Then set up everyone else to pour fire from behind.
Look for a nice choke point to set up a claymore or two, I prefer remote detonating. Wait until they are in said place, fire the claymores and open up.
