US troops to help Iraq retake Mosul

The rise in American fighting forces — and the decision to put them closer to the front lines — is designed to help Iraqi forces as they move to retake the key northern city of Mosul.
Speaking to reporters in Baghdad, Defence Secretary Ash Carter said the decision to move US advisers to the Iraqi brigade and battalion level will put them “closer to the action”, but he said they will have security forces with them and the US will try to reduce the risks.
