Well, T36s for Finns, Sotkas (I guess the Sotka is the T34/85?) the little sotkas, a BT42, 2 StuGs wich i dont remember what version, and i dont know if im mistaken or not, but i think theres a ISU something for the finns.
Also A stuka and a ME109 G10?
And for theSoviets, a YaK9, IL2, a IS2, and tons of KV1 Variants.
I still had some fun in that map, maybe not super accurate but its really fun!
Common, theres only 3 maps with Finnish on it, give it a try
