The only thing I would fear are dogs. I can hide from you, but not dogs. Will you have trained dogs? And you have to be willing to sacrifice people to get me. Are you ready for that? Will you post OP's and LPs? The military figures casualties into any plan, but will you?

The point is, you can't just hunker down and build bunkers and hope to survive. It's REALLY REALLY hard to defend a fixed position from a determined attacker. A casual, untrained, poorly armed group will probably give you little trouble, but the trained and determined person (or group) will take you down. You will always lose unless you are willing to go outside the wire and hunt them down effectively and take casualties. Because they will inflict casualties before you get them.

Look at history. All castles, no matter how well defended, always fall. It's just the nature of a fixed position. You simply cannot hold out forever.

The best defense is either a coordinated, well armed, well trained group willing to take proactive action (and casualties) or keeping a very low profile so you don't become a target. And being willing and able to bug out when you're getting overrun if you do become a target.

Just nailing plywood over your windows at your tract house and sitting in the kitchen with your 870 and your case of MRE's is not going to work when I want to take if from you.

During WW2 Saint Petersburg was never taken Moscow was never taken And they are not even castles.
A determined Defender can outlast any attacker with enough food ammo and water.
