Iraqi troops, backed by coalition forces, launched a campaign Oct. 17 to defeat Islamic State fighters and liberate Mosul, the country’s second-largest city. The operation likely would take weeks to complete, said Lt. Gen. Stephen Townsend, commander of Operation Inherent Resolve. Coalition forces – including U.S. military assets – will provide the Iraqi army with “air support, artillery, intelligence, advisors, and forward air controllers,” Townsend said, “But to be clear, the thousands of ground combat forces will liberate Mosul are all Iraqis.”
