We've also heard reports that the 3rd Infantry Division has hit resistence at the Euphrates River -- these could be some serious ground support there too.
I put my head down three hours ago: at that time, CNN's feed from the Seventh Cav was still showing nothing in front of Third Squadron. I don't think that the lead elements have run into resistance.
Planes taking off from DOHA right now, fully loaded. Methinks they're all going for the Outer defensive ring.
Be Seeing You,
