Answer
Sniping is the primary combat method attributed to Simo Häyhä's remarkable kill count. Häyhä, often regarded as the deadliest sniper in history, served as a Finnish soldier during the Winter War against the Soviet Union. Armed with a modified Mosin-Nagant rifle and exceptional camouflage techniques, he effectively neutralized enemy soldiers from a concealed position, earning him the nickname "White Death" among Soviet troops.
