Actually, what I would like to see most is another OPFOR "module." Granted, any other Middle Eastern military is going to play about the same, but how about a Russian OPFOR deployed to the Middle East for a "Bear Resurgent" type scenario? The Soviet's had a long history of indirect involvedment, and a Russian expeditionary force in the Middle East could make plausible story lines . . . plus it would allow a more "balanced" Blue v Red engagment.
