I wouldnt go as far and saying finns didnt have _anything_.
Okay. Finns had to fight a lot of battles, but this battels were not so critical like a tankbattle of kursk or the winterbattle of moscow. And i think it is a porblem fot coh to simulate this winter battles and this heavy differenc between finnish army and red army - one side tousends of tanks, guns and soldiers and on the other side some hundrets of battaillon and some caputred tanks support by two german StuG-Abteilungen and so on. i think finnish war does not have enought "material" for a game like CoH. Perhaps more for other games
