Updated with new tanks
I created these counters if you want to do a just a corner of Kursk. I have also created some UK, Canadian and some other German tanks. I have guessed on these stats and went to a friend of mine who is a game publisher (Fantasy Games Unlimited: go buy some classic RPG's), History teacher, and WWII gamer. We think these counters will play nicely with Tank on Tank and not put the game off balance. The Soviet Churchill is an earlier version than what the UK would have been using, hence the difference in the armor stat.
Counters scaled to 5/8th inch and tweaked a few things and added the UK Crusader.
