Well I hope you guys understand what Combat Mission is before you buy based on screens and an opinion or two... The CM is a unique game and not to everyones liking...please check out the web site at:
http://www.battlefront.comand maybe wait for a demo, if your not sure.
I've done three reviews of the game, they can look here as well.

IMHO it is the best tactical level wargame ever created. CMAK to me stretched the technology to the point where the game was almost unplayable, it became too big. It looks like this game is getting back to its principles, Company and Battalion level operations.
What is the largest size of unit in the game? In CMAK you could get a divsion sized element if you wanted to. Nice and big, certainly meaty but almost an irritant when you were trying to complete anything. Too much to do at one time. I can't see CM2 doing well in full real time with that size of units.
