It's the British way Arzosah
looking at it more I thought.
1 as per thread black out hide out hope they pass you by.... depends largely on where you are if you have a home in a good location which looks like an ideal place to set up base if you've bugged out, this really is not a good idea, it would make your home more attractive, similarly looters will turn over the places which look unoccupied first just like a burglar would. I have to say the more I think about it the less places I can imagine blackout and hide being a good bet.
2 make yourself look like a hard target, or be a hard target... really depends what you're facing doesn't it, you'll either scare them off or have to fight, but given option 1 looks like having to fight would be almost inevitable, I'd favour 2 in most cases
3 the evil option, look like a soft target, trap the raiders and do unto them what they were going to do to you.... well we've all got a dark side and if there comes a point where the moral compass is more a liability or a death wish, then treating potential threats this way could look like the only safe way to survive, personally I would like to think I couldn't do it unless I was certain that those heading my way were bad ones intent on doing me and my family harm and taking whatever we had, I really don't like number 3 but it's crossed my mind as quickly as did the potential futility of number 1.
These options I was looking at as an individual family, a small community would probably have a couple of extra choices.
I have a strategy, it's not written in stone, nor can it be, this scenario has too many variables, everything about it depends on those variables, being specific is not possible.
funny how there can be more than one way of looking at a problem
