Tony that is a division size force that just popped up...
Rumors had it for several days that the 2nd MEF was in Jordan, preparing to head east.
The taking of the western airfields by Special Forces units would facilitate the movement of a division-sized force.
The reporters in Amman have had nothing at all to report from Western Iraq. I don't believe this is a coincidence.
My guess is that the 101st Airborne is now west or northwest of Karbala. If I'm right about the 2nd MEF, they will join the 101st in a movement east toward Baghdad, suprising the living crap out of the Hammurabi RG Division.
