it is a realistic WW2 combat game, I think it was turn based.
"Excuse me, Herr Hitler, would you mind delaying your strategem until I've had my lunch and popped down to the shops?"
Seriously, though, I'm afraid that turn-based games have largely fallen out of favour with developers. Real-time strategy is de rigeur
these days. Company of Heroes is an excellent WW2 RTS - worth a look if you've not played it yet.
On the turn-based front, the best I've found are Civilization IV and Galactic Civilizations II. Neither seem to be what you're looking for, though - they're epic strategy games rather than tactical combat.
