So I bought the Koshka set and really need help. I find the lack actions to be a problem against much larger armies. My Grandma gets killed so easily by allied rocketmen and the big axis guns decimate her. I guess in general I just really do not know how to use this unit nor what to buy to complement her. Is Koshka in Grandma an absolute must? How do I keep my very short range on grandma effective and be a good officer. How do I get my troops to better complement her. I really really want to use Koshka effectively. Any help at all would be greatly appreciated.
