This audio book is read by Grossman himself, its almost as good as attending one of his fantastic seminars. The chapters are fairly short so it lends itself well to listening to in the car and not losing track of the content. And, of course, the content is PHENOMENAL! If you have ever read anything of Grossman's you know hat to expect, high level, intensive content with numerous references to source material (none of that "here's a fact - take my word for it.) If you are a Law Enforcement Officer , a soldier, a Sheepdog, or any other form of Warrior, this should be required reading, but listening is even better!
