I found a top 10 sniper list from 2nd world war which contains 9 soviet soldiers, and only 1 Finnish soldier. Namely:
- Stepan Vasilievich Petrenko
- Vasilij Ivanovich Golosov
- Fyodor Trofimovich Dyachenko
- Fyodor Matveyevich Okhlopkov
- Mikhail Ivanovich Budenkov
- Vladimir Nikolaevich Pchelintsev
- Ivan Nikolayevich Kulbertinov
- Nikolay Yakovlevich Ilyin
Ivan Mihailovich Sidorenko
and the only Finnish man on the list: Simo Häyhä
The page claims:
The Soviet Union was the only country that had expressly trained sniper units in the decade leading up to the World War Two, and their superiority (with the obvious exception of the top-ranked sniper on this list) is clearly displayed by the numbers beside the names of its marksmen.
What were the key factors of Soviet sniper warfare success? Only training? Equipment? If any of these factors matter, why other countries didn't do the same tactics?
