Thanks for the replies and excellent advice.

Started this campaign. Things go well at first, as I capture a couple of key points and set up a defensive counter. But as Soviet reinforcements arrive my forces are rapidly overrun. For the most part, the NATO reinforcements of Cobra choppers are taken out by missiles so they are ineffective and ...

I'll join if the game is still open.

Update:
Too late - already gone.

I would like to have a PBEM game as the union. Playing against the AI so far but should be a competent opponent plus responsive, with much to learn.

Let me know the next step if interested.
