Simo Hayha is the world's greatest sniper. He was a Finnish man who served a mandatory one year in the service, after his time there, he became a farmer. However, during the Winter War, he decided to take his rifle (a Finnish variant, M/28), sit in a tree, while it was snowing and kill the Russians. The Russians got scared after hearing of the man known as the "white death", (Hayha's knickname) and they sent troops after him. Eventually, he was shot in the jaw with an exploding bullet; but he survived, he was found by another solider and he regained consciousness the day the war ended.

He was credited with 500+ kills with his rifle and another 150+ kills with a SMG. He did it all in less than 100 days.

Only the best sniper in history.
HIs nickname (The White Death) was given to him by those of whom he kicked ass to.

He has an outrageous 505 confirmed kills, 542 and possibly more according to a researcher in some museum.

He FOUGHT for the beautiful SUOMI and never let some commie cunt to get in his way.
He is a legend and a God.
