In this Sept. 8, 2016 photo, a U.S. Army soldier guards a position at Camp Swift, northern Iraq. U.S. troops will be engaged more closely than ever in fighting against Islamic State group militants as they back Iraqi forces in the long-anticipated assault on Mosul. The assault caps an increasing American role in Iraq over the past two years, with nearly 6,000 US troops on the ground, including special forces in combat on the front-lines.
