A Great Book
Survival is a skill, and one you need to work on, you can have all the books in the world but unless your actually go out and try these things it's nothing but a collection of paper.

that being said this is an excellent source of information that you can use to attempt trapping food (Please check that it's legal in your area and remember where you placed all your traps as well as make sure you take them down after you have proven they work.) making camps and fire, cooking and eating and so forth.

hopefully you will never NEED This book, but if you do i hope you made the right choice and bought it.

The definitive guide to survival!
This is THE definitive guide to survival. There is nothing here to filter out, no political rhetoric, just straight fact and easy-to-understand instructions on how to survive in any wilderness situation. The extended sections on the Arctic were of particular interest to me because I happen to live in that zone. EVERYONE should keep a copy of this in their home, car, and camper!

Survival Guide
A needed reference for any one who is into survival. Written for the solder in all of us.

It IS a military manual after all
As a civilian I found myself filtering a lot of the information and wondering how I would adapt if I ever encounter any of the scenarios. I did enjoy the information on the psychology of survival. It gave me food for thought in rounding out my emergency gear.

Why buy what you can get for free!?
I would recommend, as another poster has, to download this book for free just by using google and inserting Fm 21-76, then print in out, although paying for printing could be more? Don't waste your money if you are ok with digital copies.
