Cost of U.S. Government Intervention in IRAQ (War against ISIL) mid-June 2014 to August 26 (Pentagon official to Congress)

from Washingtonpost.com / News/Checkpoint (Article by Dan Lamothe):
The U.S. has launched at least 110 airstrikes in Iraq since August 8, 2014, U.S. military officials say, and it now has hundreds of military advisers and other personnel on the ground there to assist Iraq in its fight against Islamist extremists.
How much is that costing U.S. taxpayers? An average of $7.5 million per day since mid-June, Navy Rear Adm. John Kirby, the Pentagon’s press secretary, said Friday (August 29, 2014). After more than three weeks of airstrikes and humanitarian operations in Iraq, that likely easily exceeds $600 million.
Kirby’s comments mark the first time that a U.S. official has attached a price tag to the U.S. military mission in Iraq since President Obama authorized it to expand on August 7, 2014.  Airstrikes began the following day, and it is now rare for a day to go by without U.S. Central Command, which oversees U.S. military operations in the Middle East, announcing at least one strike.
Kirby said that $7.5 million average includes the cost of operations in Iraq since mid-June, well in advance of Obama escalating operations there in August. The figure is based on figures through Aug. 26, Kirby said.
