There are quite a few other books on sniping that you need to buy before this one. I do not know about the background of the other reviewers but to call this a good book on sniping is BS. A very, very light introduction, maybe, but the book does not cover ANYTHING in detail. It is at best useful for a wanna-be sniper and maybe not even so: If you include so little details, but still manage to explain where to shoot a man in the head it is at best missguiding.I am sure that mr. Lonesdale knows his stuff, but this book is lightweight.
