Layered Systems and Redundancy

I believe in layered systems. Sort of did this before really learning the concept in a more formal sense but it is easier to do well with the basic concept in your head. It sort of goes like this. Instead of having a whole bunch of stuff all over the place you have a few systems. These systems are layered from smaller to larger moving from the most basic things in your pockets to larger systems that may fit in a backpack or even a vehicle. The saying that you survive out of your pockets, fight out of your kit and live out of a rucksack is a solid starting point.

The two systems we will talk about today are my everyday carry and my EDC/ Get Home Bag. I should post pictures of this stuff and talk about why this is there and that is not but that's another post.

On Friday I reached into my pocket for a knife and it wasn't there. For whatever reason the knife just didn't make it to my pocket that morning. A further inspection showed there wasn't a lighter in my cargo pocket either. This wasn't a huge deal as I was going to use it for something minor that I can't recall. I had another knife (as well as a lighter) in my bag but didn't bother to dig it out.

So this got me to thinking. Things happen in life. Maybe you leave home in a different pair of pants or an item is lost or stolen or whatever. Within a layered system you still need some redundancy of key items. The old saying two is one one is none comes to mind. Furthermore I think these redundant items should be spread out. Having two knives instead of one sitting in my other pair of pants at home would not help. On the other hand a knife in my bag is a lot more likely to help. This also has the benefit of letting you have slightly different tools for different jobs. Maybe a Leatherman and a more dedicated cutting tool for your knives or a Lazer Bright stick and headlamp for lights.

Kind of along these lines my EDC/ GHB bags contents has been evolving.  The new Pathfinder water bottle pouch helps because it is pretty large so a lot of those little survival things can go there. A box of granola bars was tossed in giving me about 1,500 calories worth of food to make up for a couple missed meals. I'll probably do a write up on the contents when it is a bit more settled.

Anyway that is what I have been fiddling around with lately.

Do you have some redundancy in key items? What items do you consider key?

I tend to agree...

First, I consider anything in my "first line" to be key, and the entire first line is replicated at least in the third line, in some way.

For example, if I EDC a knife and a light, then a keep a spare knife in my car's bail-out-bag (effectively a 2nd line) or rucksack (third line).

Second, I think about effects, not about items. I don't keep a spare handgun in my vehicle bail-out-bag or ruck. That would be an invitation for theft and would also pose problems if I accidentally drove into a Victim Disarmament Zone. I do however keep a can of bear spray and a small fire extinguisher in there (being from Alaska of course). Different item, similar effect (self defense capability) created. I may carry a nice flashlight, and the spare in my ruck is a headlamp -- different item, same effect (light).

Canteens and canteen covers - hard to have too many in a fixed position. I've even taken to carrying a few with a 1 qt. canteen in 2 quart cover - you can cram some extras in the empty space and still have one container. The strap from it also comes in handy at times - can bind and fashion a handle for gathered firewood and other long items.

Multi-tools - sometimes having one handy for things that happen HERE save a lot of trouble and mess. Went to my kids catechism school and needed to go to restroom - a leaky water valve under one the basins had gone bad and had a BAD leak, flooding the floor. Having a Wave right there saved them from a lot of clean up later on.

Man, redundancy gets expensive but when it pays off, it pays off big.

For us, we try to make redundancies for as much as we can. In some cases, even tertiary levels of backup. Obviously guns are one of those items. However, other things like water containers, backpacks, heating and lighting sources, fuel handling things, etc, etc, all get at least a secondary level of backup.
