Also, for those that are in for the long haul or true believers in SHTF, I would like to suggest two books for your shelf. I know you guys like to substitute books for hands on.
In this case I can understand that and recommend it. I had a copy of the 1966 edition of Small Arms Of The World and studied it until it fell apart. Using only that book knowledge I conned my way past a Special Forces screening session and was the only person in my training company that knew how to disassemble, reassemble and operate every piece of Soviet hardware from WW2 forward. It did not get me into SF but it landed me a cushy temp assignment for a while.
What I am saying is that study of the books is of value, along with a basic safety and marksmanship course.
The first is Small Arms of the World. The last edition is from 1996 and some of the most modern weapons are not included, but the basic military small arms used by the major European powers are included as well as history of firearms and all military hardware in general use since WW1.
This book is not only a recognition guide it also details the maintenance, cleaning and operations procedures for every weapon used by any nation that matters.

The other book is by Hagg, one of your own from the Royal Artillery School.
Janes Gun Recognition Guide.
The difference between the two is a bit like the difference between a huge plant identification book and the same book with recipes for cooking the plants.
The Janes book is newer and will have some things the SAOTW does not, but no real technical instructions. The person that was responsible for SA is now deceased and there will probably never be an update of the same quality.
