If you're up for some Blue-on-Blue I can go Brits or USMC. If you'd rather keep it Blue vs Red I don't have a problem being the Syrians.
Something like a large/huge meeting engagement seems good: enough points for the whole combined arms show to come out and play, a meeting engagement means both players have to act.
If we can't nail down a good ME map, then I'm equally happy fighting an attack-defend.
