Your home?
The only thing I have going for me is that I live atop of a hill (so to speak). I have some pretty good vantage points as do my neighbors. We actually live in the inner circle of the outside threats if hordes came.
I would have to leave my abode to help the neighbors on the perimeter; it is what it is. They fall, I fall.
The only hope I have is if the attackers were few and easily discouraged.
