As an interesting bit of trivia, from 1918-1945 the Finnish Air Force's symbol was a blue swastika.
I first heard of the Winter War when I lived on Michigan’s Upper Peninsula back in the 1970s. I’d hang around the American Legion or VFW and some of the guys talked about their grandfathers, fathers or uncles fighting in the Winter War.
The stories they related were incredible.I forgot the name of that Finn sniper, but it’s estimated he had somewhere around 600 kills using an iron sight Mosin-Nagant. Wow!
