Query: A total waste of money

Do not purchase this book, if you are interested in this topic, there are many other fine books out there. This book is a joke though and i cant even believe someone published it. In the book they show a picture of Air Force Security Forces personnel (Basically Air Force Cops) and because they have the "SF" armband on they claim the personnel to be Army Special Forces...with Air Force rank staring you in the face. Anyone with half a brain can see that this book is terribly written, researched and produced, it is clearly marketed towards the naive and uninformed.
