I don't think so

Many many news reports about an incident in Baghdad where Blackwater contractors (see http://www.blackwaterusa.com/ for details on the company) had a shootout in the streets with 'insurgents', leaving somewhere between 6 and 10 Iraqis dead and several wounded. (The stats vary, as is usual with war reporting.)
But the gotcha in several of the reports was a note that a Blackwater helicopter had taken part in the action, spraying the insurgents on the ground and, presumably, causing some of the claimed civilian casualties.
Helicopter? Now, I know that the civilian contractors have gunned-up for their mission, but somehow I don't see the Army permitting a helicopter (especially an armed one) to be flown around Iraq by civilians...
