Nah. During the 4-month Russian invasion of Finland, 1939-40, the Finns found out that the 9mm fmj rounds from their kp31 *Suomi* machinepistols were just fine for killing unwanted Communist invaders. You just had to use enough of them to get the job done.
The Finnish proverb "Siberia shall teach" was true also in the form: "Siberians shall teach". Many "Russian" invaders in the Winter War of 1939 - 1940 were actually conscripts from Ukraine and other south-western republics of Soviet Union. Many Russian soldiers of the north-western front in the 1941 - 44 war against Finland were tough and persistent natives of the Siberian wilds and forests. Some Finns knew them from the earlier war.Now pull your trigger on the link here, and learn how the busy Finns were doing the good work of killing off unwanted Communists before you were born.
"They were formidable opponents. We were urged to kill almost every Siberian twice, and most tough boys still a third time", told many Finnish veterans of wars: "Russian lads, coming against us in closed formation, intoxicated with vodka and singing Le Internationale, were bunny-boys but the Siberians were born soldiers! We met them in February 1940 and we learnt to respect those slant-eyed imps... !" Two bullets were enough for "bunny-boys" but five hits were necessary to dispatch a Siberian "imp". Sometimes they fought back despite ten or twelve wounds from 9 mm bullets.
I was just teasing - I heard that from someone once, who was making fun or Europeans. Thought it was funny :)
