Well, Nazi German would have easily won the war if they wouldn't have had so many enemys.
I personaly think that Finnish army was one of the greatest at that time. They had crappy weapons, only a few tanks etc., but they still basicly kicked Russians ass, even tough they lost the war.
Russians had 4000 cannons, 2000 tanks, 1000 airplanes, and an army of half million men.
Finns had 280 cannons, few tanks, 60 airplanes, and 300 000 men.
And Russians still couldn't beat them.
I've also read that one of the Finnish generals got shot a shitload of times and almost got killed a few times, but he always wen't back.
