This is not a patch idea, but more of a sequel story line.
I'd like a campaign to take place in the states. Possibly involving nukes having taken out half the east coast, and the enemy invading. The characters could be stationed at Fort Hood, TX and both the 4ID and 1st Calv divisions would be mobilized to take out the threat. The joy of using Fort Hood is that the 2 divisions have planes, helicopters, more tanks and arty then you'd care to count and then all the supporting infantry and vehicles.
I think this could make for an interesting story line and game play. The only problem I can think of is who the invaders are and where. I'd say after nuking the northeast and eastern coast, they'd probably want to try the south or southeast. However, due to PR and political issues...who would the invaders be?
I'm in Bosnia working for the military as a civilian contractor, it would be nice to drive my tank to Dallas and give the wife some sugar. haha
Take care,
