I have a bunch of military field manuals and survival guides, but they all implicitly presume the existence and contactability of civilization sooner or later. Realistically, some pocket computer(s) and solar charger(s) will store far more information, be far more portable, and give you more carrying capacity for things like medical supplies, rope, tools, and other hard-to-substitute items.

Have you re-read it recently? Some of those books were fun to read but not really something to use as a field manual. Then again some of them were great! I had a book that started with explaining how a battery and a light globe worked, went through how to make a DC motor out of copper wire and a cork, and ended with a crystal radio and I think a radio homing beacon (the latter might have been in another book.)
