This classic work on sniping is considered the first and some say the most influential book in print about sniping and the art of being a military sniper on the battlefield. McBride's book was seminal in the development of U.S. military sniping doctrine in WWII, Korea, Vietnam, and on to the present day.
The U.S. Marine Corps Sniper School has made this book mandatory reading for its would-be snipers.
