Well as people prefer to play their own nation more and Finnish RO community got
best players, that will be enough.
But seriously talking.
Well i think biggest difference between Finnish and Soviet army is tactics.
Finnish soldiers were trained to fight on small units or even in pairs,
while Soviets were trained to work as a bigger units. That was maybe
biggest advantage to Finland in Karelian Front which is more like deep forest.
Which as a fighting environment works little bit like jungle where small and
mobile units are effective.
How ever its hard to implement any tactical advantages or disadvantages to game.
Maybe faster and more accurate artillery could be one, what we could think about
as finnish artillery was most accurate at the time and played huge role 1944 on stoping
