This is the third book in the series (or three) by Darren Levine and co-authors (Ryan Hoover in this case). Pitched as 'Black Belt Krav Maga - Elite Techniques of the World's Most Powerful Combat System', this book presents techniques in terms of specific situations / threats ('handguns', 'carjacking', 'edged weapons') and includes chapters where the defender is armed ('blunt objects vs edged weapons' for example). The first book in this series ('Krav Maga For Beginners') introduces 'combatives', 'defensives' and 'groundfighting', the second book (Complete Krav Maga) takes a belt based approach outlining techniques associated with different 'grades'. All of the books in the series have a similar layout and include clear text and photographs taking readers through the different techniques.They also outline some of the key principles of Krav Maga. While some of the situations / techniques are hopefully ones most people will never encounter (e.g. disarming an assailant who is armed with a hand grenade!), this book does represent a step up in terms of the responses presented. Along with that a certain level of experience of, and familiarity with, the techniques contained in the other two volumes is assumed and built on. NO BOOK WILL TEACH YOU TO BE A MARTIAL ARTIST and no book can replace regular attendance at a reputable club...BUT publications like this one can act as a reminder of techniques learned in class. However, for a book best suited to that role you would be better off with the second in this series - Complete Krav Maga. This particular book is a good complement to the others in the series, and the series as a whole are better that some of the others on the topic of Krav Maga but you'd be best off to join a class and practice, practice, practice!
