This group has been allowed to operate in Iraq upon it's own judgment ASAP upon its own intel evaluations to keep the heat on the insurgents.
This group does not need clearance up the chain to Central Command to plan and execute its next mission.
So, I imagine Jihad Johnny has not been getting a lot of sleep lately and have now figured it best to leave Iraq to Syria as fast as he can move.
Army Lt. Gen. Stan McChrystal, JSOC commander, spends much of his time in Iraq, his job there is to coordinate with Army Gen. John Abizaid, chief of Central Command, and other senior leaders. The man in charge of TF 145 is the Delta Force commander, a colonel and cannot be named at this time (security reasons).
Check out the May 8th issue of The Military Times from which some of this info was published.
I say, flush'em then fry'em!!
