“Consider getting a book called A Failure of Civility written by Mike Garand and Jack Lawson. Two guys with urban spec ops training. I saw it here on FR. A technical guide to turning urban areas into defensive zones among many other things.”
I have that book. I am one person and I disappear in such a case, with unseen from the outside, security measures. Think urban camouflage.
Here’s the short version (81pgs) “break-in book”, in *.pdf form:

I kept several military uniforms from several years ago that are not the digital print. They fade into the surrounding area very well. I also have the digital print uniforms for hunting. I will survive on fresh game if needed.
