During the Winter War (1939–1940), between Finland and the Soviet Union, he began his duty as a sniper and fought for the Finnish Army against the Red Army. In temperatures between −40 and −20 degrees Celsius, dressed completely in white camouflage, Häyhä was credited with 505 confirmed kills of Soviet soldiers. A daily account of the kills at Kollaa was conducted for the Finnish snipers. Remarkably, all of Häyhä’s kills were accomplished in fewer than 100 days – in other words, an average of 5 kills per day – at a time of year with very short hours of daylight. On March 6, 1940, Häyhä was shot in the lower left jaw by a Russian soldier during combat. The bullet tumbled upon impact and exited his head. He was picked up by fellow soldiers who said “half his head was missing”, but he was not dead: he regained consciousness on March 13, the day peace was declared.
and this is why no one fucks with the Finland.
