You're bunker doesnt sound very defendable.
I can't help but think you're defenses would amount to anything more than "hey lookee here i have lots of stuff worth stealing", 1 man or a small group is not going to be able to defend itself against a determined force even with the defenses you describe, and hey if we are talking doomsday scenarios, thats gonna happen.
... and all of my planning hinges on any attacker being no brighter than this dude. This is approximately what I expect. I reckon people like this would not get beyond perimeter one. Since there are six rings of defense possible around the shelter, this is the kind of guy I would just expect to find dead on the perimeter while I am out trimming the hedges. My strategy assumes a native intelligence equivalent to this rocket scientist.
As you approach my property from about 200 meters out, you'll want to seek the natural cover afforded by features in the terrain, little dips and shallow pits where you can peer over the crest and observe my shelter for a while before advancing. You'll want to do that because this is where my motion detectors are planted and it is also where my claymores are pointed inside of, actually from behind you, to make sure no shrapnel escapes these hollow depressions without passing through you first.
Maybe you're too clever for that and instead will choose a slow creep up the ravine. This is great because it is lined with CCD cameras and at the mouth of the ravine is a small concrete cylinder poking out of the ravine wall. You'll be relieved to know that we don't intend to shoot anybody from this observation point, though. It's just a remote perch where we can watch the homemade napalm cannon flood the ravine with sticky flaming fuel out to about 100 meters without any hope of cover. It's basically like being inside the mouth of a blowtorch. Later, we will dispose of your charred carcass by simply chucking it over the ravine wall on the other side. Please, consider our convenience when you breach the perimeter. A frontal assault is the best way to go. Your odds are better if you just strip naked and run screaming towards the hill, you will probably get a higher score in terms of distance before death from the hatch.
One of the greatest features of my mountain is that is it always chockablock with dead wood, so should we come under attack by a force of more than 100 people (unlikely this millennium, but still) we simply light up the entire mountain and seal the blast valve. Within a half an hour, temperatures outside climbing to 600 degrees in the resulting uncontrolled firestorm will pretty much clear the entire plain out to 4 kilometers, with the only hope of survival to immediately evacuate the area ahead of the fire.
Did I mention my tritium markers for night defense? They are placed in a clocklike circle allowing us to concentrate fire on a map oriented correctly even in perfect darkness to hit people who are hiding exactly in front of the locations where the tritium markers are mounted.
