Query: A no non sense book.

This is a book that gets to the point, and gives you what is useful in the real world situation. There are no katas, or useless moves that could get you killed. It starts off with blocks, deflects, and strikes. Then goes into different weapons and bayonet fighting both defensive, and offensive moves. After that it covers joint locks, chokes, and takedown moves both defensive, and offensive. This book would do slightly better if only it has more pictures illustrating the moves besides describing them word for word. All in all this is the real stuff that anyone can use to defend themselves instead of getting killed.
