This book approaches, in an educational way, the techniques of striking with a handgun in most of the critical situations that a professional in the field of combat or security may be confronted with at close range. The techniques that the reader will discover in these pages were elaborated and developed by and for Israeli army units over the past fifty years, which were passed on to the authors through the Krav Maga they have been practicing for decades. The more than 200 pictures and diagrams in this book will allow the reader to train alone or with teammates and will help him to face critical situations that he may encounter during his professional activities.
