This book is broken in to mainly two sections, history and practice. The history section is a very good read. I had no idea how influential Asian-Indian combat tactics were. The practice section is full of information you probably shouldn't know. After reading this it is almost painful to watch movies where anyone gets taken out by a sentry. The book is rather short and can most likely be read in under a few hours. There are positively brutal diagrams and some information on the human anatomy I'm less comfortable for knowing. This is truly a no BS history and lesson on how to attack the neck of another human being, and also some information on stalking. It's definitely a permanent addition to my 'WTF' collection of coffee table books.
