This is a photo of Simo Häyhä, a Finn also known as "The White Death" - and is widely known and accepted as the World's Greatest Sniper. The photo was taken during the Winter War (1939-40) with Russia. He has over 500 confirmed kills, and died only recently. He didn't use a scoped rifle - he prefered shooting over open sites.
