I don't know. I am thinking something like On-Star or a IFF system. It is possible that some of our cars over there are equipped with that and if this car didn't have it and was hurling toward the checkpoint then that would be a good reason to open fire.

Yeah, U.S. military vehicles have the capability to track each other using the "blue force tracker" system. I've never heard of putting this system into civilian cars. But now that I think about it, it might make sense to do this in Iraq for friendly vehicles.
