"It is a fire base," Col Steve Warren, spokesman for the US military headquarters in Baghdad, told reporters at the Pentagon.
It is the first such base established by the US since it returned forces to Iraq in 2014 in response to the Islamic State's takeover of Mosul and other areas of northern and western Iraq, Warren said. He said it should not be considered a combat outpost because it is located behind the front lines and is not initiating combat with the Islamic State.
On Monday, a small number of Islamic State fighters got close enough to the Marines' outpost, dubbed Fire Base Bell, to target them with small arms, Warren said. He said no US personnel were wounded in that attack; two IS fighters were killed.
He said the Marines' mission is defensive and is considered part of the advise-and-assist mission the US military is undertaking on an Iraqi military base located near Makhmour, between the cities of Mosul and Kirkuk.
