Simo Häyhä
Using a standard iron-sighted, bolt action rifle in the Winter War, he has the highest recorded number of confirmed kills in any major war. In temperatures between −20 and −40 degrees Celsius (−4 and −40 degrees Fahrenheit), dressed completely in white camouflage, Häyhä was credited with 505 confirmed kills of Soviet soldiers,and 542 if including the unconfirmed deaths. The unofficial Finnish frontline figure from the battlefield of Kollaa places the number of Häyhä's sniper kills over 800.
