(AP Photo/Hasan Jamali, File) (Newser) – The US has spent more than $2.7 billion on the war against ISIS militants in Iraq and Syria since bombings began last August, and the average daily cost is now more than $9 million, the Pentagon said yesterday. Releasing a detailed breakdown of the costs for the first time, the Defense Department showed that the Air Force has borne two-thirds of the total spending, or more than $1.8 billion. The daily combat, reconnaissance, and other flights eat up more than $5 million a day. The data also provided a rare look into the often secret special operations costs, which totaled more than $200 million since August. Other total costs include $438 million for the Navy, including fighters and other ship support; $274 million for the Army, which has trainers and special forces troops on the ground; $16 million for military pay; $646 million for munitions; and $21 million for intelligence and surveillance operations. The release of the spending totals came as Congress debated and rejected legislation yesterday that would have banned spending on the combat operations until lawmakers passed a new war powers resolution.
