The body of 19-year-old Berzan Ibrahim Khelil, who was killed by a mortar during fighting between the Iraqi forces and ISIS militants is carried to a cemetery on a cart by his cousin in Mosul, on Nov. 17. As the operation to retake Mosul enters its second month Iraqi forces are preparing for prolonged, grueling urban combat as they slow the tempo of their operation, advancing just a few hundred meters at a time. The individual tactics employed by IS mirror past fights with the group, but the sheer scale of IS defenses and counterattacks in Mosul has overwhelmed Iraq's military.
