Omar at Iraq the Model posts a cellphone snapshot of a B-1 Lancer a few thousand feet over his city, apparently as part of the crackdown of the surge which, he says, already is being felt by residents:
"On the streets, checkpoints and roadblocks are becoming increasingly serious and strict in doing their job; soldiers and policemen are sparing no vehicles or convoys from searching and I personally saw a case yesterday where an ambulance driver tried to rush his vehicle through a checkpoint but the soldiers ordered him to stop and let him pass only after they checked the inside of the vehicle finding only a civilian medical emergency."
As for the B-1, its satellite-guided, 500-pound GBU-38 "reduces undesired collateral damage and is very useful in urban Close Air Support," according to Wikipedia.
