Operation Inherent Resolve, the war against ISIS in Syria and Iraq, is now a year and a half old and has cost $6.2 billion. The Pentagon is asking for another $7.5 billion to continue the fight. The cost of the war against ISIS is relatively cheap (s0 far) when compared to the Iraq War, which came to almost $2 trillion over the eight years it was fought.

The war against ISIS isn't going to get any cheaper, especially especially in light of the fact that it's spreading to other countries like Libya and Afghanistan. Combating their forces on the ground will require more air power and more special operations units backed up by all the necessary logistics commands.
As of March 9, 2016, U.S. and coalition aircraft launched a total of 10,870 air strikes, with nearly twice as many in Iraq than in Syria. The strikes have hit a total of 21,501 targets, mostly buildings and ISIS fighting positions.
The average daily cost of the operation is $11.5 million. The most expensive ops belong to the U.S. Air Force, a whopping 69 percent of the total cost.
