Combat Mission: Touch. It's more of a tactical game than strategy like the ones you mentioned. It is however, one of the few games I can think off that uses combined arms in the traditional sense, armour and infantry with artillery support.
I found it clunky to begin with but pay attention to the training video and you will be slapping Jerry around Normandy in no time.
