Written by George W. Jasper, former U.S. Army Ranger and the commander and chief instructor with the United States Rescue and Special Operations Group),
U.S. Army Survival Manual FM 21-76 pales by comparison to this survival manual. 6 ways in & 12 ways out is a much more advanced survival manual written by the folks who have "been there".
The information and skills contained in this book are generally reserved for training the elite. Don't ever complain "if only".....because this is your chance!
