You might wonder why the list is dominated by Soviet soldiers, when today's expert marksmen come from all over the globe. The U.S.S.R., however, was the sole nation to offer sniper training to it's military in the decade preceding the war. Although none were prolific enough to make this list, it's also interesting to note that the Soviets fielded as many as 2,000 female snipers as well, including some who recorded more than 200 confirmed kills.
