Here's another: Simo Hayha (AKA The White Death)
During the Winter War (1939–1940) between Finland and the Soviet Union, Häyhä served as a sniper for the Finnish Army against the Red Army in the 6th Company of JR 34 during the Battle of Kollaa. In temperatures between −40 °C (−40 °F) and −20 °C (−4 °F), dressed completely in white camouflage, Häyhä was credited with 505 confirmed kills of Soviet soldiers.[2][4] A daily account of the kills at Kollaa was made for the Finnish snipers. All of Häyhä's kills were accomplished in fewer than 100 days – an average of just over five kills per day – at a time of year with very few daylight hours.[5][6][7]
Häyhä used a Finnish militia variant of the Russian-made [unmentionable], chambered in 7.62×53R, the Finnish [unmentionable] cartridge, because it suited his small frame (1.6 m (5 ft 3 in)). He preferred to use iron sights rather than telescopic sights to present a smaller target for the enemy (a sniper must raise his head higher when using a telescopic sight), to increase accuracy (a telescopic sight's glass can fog up easily in cold weather), and to aid in concealment (sunlight glare in telescopic sight lenses can reveal a sniper's position). As well as these tactics, he frequently packed dense mounds of snow in front of his position to conceal himself and provide padding for his rifle. He was also known to keep snow in his mouth whilst sniping, to reduce steamy breaths giving away his position in the cold air.[8]
The Soviets' efforts to kill Häyhä included counter-snipers and artillery strikes, and on March 6, 1940, Häyhä was shot in his lower left jaw by a Russian soldier. He was picked up by fellow soldiers who said "half his cheek was missing", but he did not die, regaining consciousness on March 13, the day peace was declared. Shortly after the war, Häyhä was promoted from alikersantti (corporal) to vänrikki (second lieutenant) by Field Marshal Carl Gustaf Emil Mannerheim.[9]
