Urban Survival Preparation - More on Home Defense

I received another question on face book (see Urban Man on Facebook) regarding my previous post on Home Defense Preparation (view it by clicking here). The question was concerning enhancing interior wall protection, especially around the windows which would be your home’s observation and firing ports, what would be some materials other than sand bags, sheet steel and heavy layers of plywood to enhance this protection.

The diagram I placed on the aforementioned Home Defense Preparation post showed protection on both sides of the window. I failed to note that protection underneath the window is a good idea also. But primarily outside the window frames as people in your survival group assigned to this window should be observing (and firing if need be) from outside the frames of the window. This is actually a concept derived from the Vietnam War called the DePuy fighting position (replaced the old foxhole), providing interlocking fields of observation and/or direct fire with small arms, with protection from frontal fire. The DePuy fighting position diagram is shown below.

The below diagram shows how multiple DePuy fighting positions provide multiple interlocking fields of observation and fire, and being mutually supporting, while providing frontal protection.

So basically, we are just applying the DePuy fighting position concept to your home. We also believe in a Defense in Depth concept. Fences, barriers, cleared fields of observation and fire in order to interdict attackers at the earliest opportunity and to slow any assault on your home. Cut down telephone poles, large rocks, T-posts, etc., driven into the ground at a sufficient distance from your house will help prevent vehicles being driven up to or into your home. This is like the large concrete, dirt filled planters that the government positions in front of their facilities – to deter car bombs.

Anyway, back to what you can do to harden or enhance protection for your interior walls. Sand Bags, are available from multiple sources on the internet, recommends the burlap bags as opposed to the newer nylon bags with rapidly degrade. In any case line these bags with plastic 13 gallon garbage bags to help reduce sand spillage. When filled each sand bag weight about 50 lbs. The advantage of sand bags is the contained and compressed sand provide good protection from small arms fire and are easily used to customize to your needs. The disadvantage is they are hard to stack high and remain stable.

Cut down rail road ties are easily stackable and provide great protection from small arms fire. A thin sheet of plywood can be added in order to nail or screw the railroad ties to to form a stable wall. You would cut down rail road ties to workable lengths. These are available at most landscaping places and some major home improvement stores.

Sheet steel is great, doesn’t take up much room, but is heavy. One quarter (1/4) inch sheet steel is common and easy to move in small packages, say 3 foot by 2 foot pieces, but hard to integrate into your interior protection unless you lean them up against the wall (not a bad idea). However, 5,56x45mm NATO rounds (or .223 Remington) even in the 55 gain ball configuration will penetrate ¼ inch steel. The idea is for the exterior wall of the house to slow the round allowing the sheet steel to stop the round. mentioned plywood because it is an easily available material. Many homeowners in Florida (Hurricane country) has pre-cut sections of ¾ inch plywood ready to be placed over their windows when hurricanes are heading their way. Plywood can be cut to configure around windows frames and can be nailed or screwed together in layers to provide better protection. However wood will just not have the bullet penetrating stopping power that the others materials do.

Even buckets filled with dirt or water and placed on the interior wall will provide some protection. With round buckets you’ll have several weak points where the buckets abut each other. I guess you do what you can do. The whole idea here is to harden your house for an asault from gangs or mobs. A successful defense may make these groups go elsewhere in search for an easier target.
