Not sure if these are what you are looking for but:
wartimes, gameplay is similar to what you see in CC:Generals, but set in ww2 timeframe with germany or the allies being the sides to use. A pretty straightforward WW2 RTS. The thing I did not like was the tank upgrades being a bit too powerful IMO. In generals, you stood a chance against the Chinese overlord tanks. In this game, I can take 3 tiger tanks and nearly wipe out my opponent, or at least buy enough time to build 3 more Tigers for another wave immediately. Granted this don't always happen, especially on smaller maps as researching costs resources. The game flopped, I see it on shelves here in the states for 10 bucks now.
The other ww2 RTS I have played is Blitzkrieg, with Blitzkrieg 2 on it's way later this year. A realistic game. Tanks have armor values for all 4 sides of it, making the direction you fire from important. Realistic and detailed, definitely a game to check out if you want realism. The thing I did not like about this game was the maps were kind of boring. No naval units and limited air. You do not have much control over the planes beyond calling them in and giving them a target. But you just got to love a game with a difficulty level called "suicide"
