I find it tough to have a lot of respect for somebody who allows that title on his book. I guess he took a lot of shots at ducks on a pond and piled up "confirmed kills". Good for him. He's no Marine Corps sniper, though. He is definitely no Carlos Hathcock. About 90% of being a real sniper is "stalking". Maybe he should see if he can make it through USMC Scout Sniper Basic School before he writes another book.
Try reading the book before you comment. He has good things to say about Marine Snipers as well as the value of stalking.
