Pentagon watchdog chosen to oversee Islamic State combat operations

United States government efforts to fight and ultimately destroy the Islamic State in Iraq and Syria have grown large enough to warrant special oversight.

Jon Rymer, the Department of Defense's inspector general, will lead a coordinated effort with officials from the State Department and the U.S. Agency for International Development to keep tabs on the resources all three agencies dedicated to suppressing the deadly Islamic extremist movement.

His designation by the Council of the Inspectors General on Integrity and Efficiency marks the first time ever a lead IG has been named for an overseas contingency operation by American military and diplomatic forces.

The Defense Department launched Operation Inherent Resolve against the Islamic State in late 2014. Operations related to the fight have cost more than $1 billion since August 2014 and require an average of $8.1 million each day to sustain, according to the Pentagon.
