Simo Häyhä

Simo Häyhä "was a Finnish soldier, and is widely considered to be the most successful sniper in history"

"The White Death"

During the Winter War (1939 – 1940) between Finland and the Soviet Union, he began his duty as a sniper against the Red Army. Working in temperatures between −20 to −40 degrees Celsius(-4 to -40 degrees Fahrenheit), and dressed completely in a white camouflage suit, Häyhä was credited with 505 confirmed kills against Soviet soldiers.
The unofficial Finnish frontline figure from the battlefield of Kollaa places the number of Häyhä's sniper kills at 542.

Besides his sniper kills, Simo Häyhä was also credited with as many as two hundred kills with a Suomi M-31 SMG submachine gun, thus bringing his credited kills to at least 705.

On March 6, 1940, Häyhä was shot in the jaw during close combat. The bullet tumbled upon impact and left his head. He was picked up by fellow soldiers who said "half his head was missing". He regained consciousness on March 13, the day peace was declared. Shortly after the war, Häyhä was promoted straight from corporal to second lieutenant by Field Marshal Carl Gustaf Emil Mannerheim. No one else has ever gained rank in such a dramatic fashion in Finland's military history.

It took several years for Häyhä to recuperate from his injury. The exploding Soviet bullet had crushed his jaw and blown off his left cheek. Nonetheless, he made a full recovery and became a successful moose hunter and dog breeder after World War II.

So tough. He lived until 2002 at the age of 97.
