Give Achtung Panzer: Kharkov 1943 a try. For its price you cannot go wrong, and honestly, I am superbly impressed with this game. It's much more polished than any recent Combat Mission (shock force) release, and although its scope right now is very small and it lacks multiplayer, it is a great little game. It's much more similar to Close Combat than Combat Mission in terms of game flow, although the maps are way bigger.
Here's a review for instance:

I heartily recommend it, anyway.
