There were German, and Russian snipers in that War that racked up hundreds and hundreds of kills. Only witnessed and verified kills count, so there true number is likely twice as high.
I just read a book written by a German WW2 sniper, and I learned quite a lot of tactics from him. He accounts to a time that he single handily saved him and his friends and wiped out an entire Russian squad, like 20 men. Fascinating read, even if he was on the wrong side of history.
Snipers were to be instantly killed if captured, so he carried a regular infantry rifle, as well as his sniper rifle, which he could discard if needed. Even made good use of a captured Russian Mosin if I remember correctly.
