This is a great book. Good photos coupled with good description of techniques. I found it to be a good resource for review as I prepared for belt testing and I will refer back to it often. If you are new to Krav Maga, this is a good resource, but should be used as a supplement with live instruction from a Krav Maga studio. My instructors are very good at teaching the discernment necessary when engaged in a live scenario rather than just book technique. Whenever possible, you want to avoid conflict, however that is not the world we live in, so if you are being attacked, you should be able to read the situation. Is this person drunk, angry, want to kill me, rob me or something else? My response is to defuse the situation and disarm if necessary, but their may be life/death situations where you need to go full throttle in order to survive the day. For example, I had a situation a while back where a man was agitated with me. I don't know why, but I could tell that he was most likely angry at another situation and looking for an excuse to take it out on someone. I determined while praying, yes literally praying, that I would try and diffuse the situation unless he had a weapon. Perhaps I could speak with him about his misdirected anger. Before any violence had been exchanged, he chose to flee which was an answered prayer. Being mentally prepared for these types of situations requires training in a studio with live attackers and simulations, something you cannot get from any book. The book is a valuable resource, I highly recommend it and I highly recommend learning Krav Maga if you are considering a self defense skill. You will learn technique, mental toughness, discernment, humility, courage and the skills to be book smart (for testing) and street wise for survival. My studio trains police officers and military service men. I also appreciate that my instructors share my faith and the principles to "be at peace with all men so long as it depends on me" (Romans 12:18). More of a Krav Maga review than a book review, but I still hope you pick up this book.
