The Pentagon is sending up to 100 more Marines to Afghanistan

The Pentagon is sending up to 100 more Marines to Afghanistan to help shore up internal security for the current contingent of troops already there.

"Dozens" of Marines assigned to Central Command's special purpose task force will join roughly 300 Marines currently at Camp Shorab in Helmand Province. The deployment of additional Marines came following a request from Brig. Gen. Roger Turner, according to NBC News.

The Pentagon told Marine Times the number of Marines headed to the region will number less than 100.

The Marines are likely to come from 2nd Battalion, 7th Marines, a 29 Palms, California-based infantry unit currently serving as the ground combat element for the task force.

"Periodically, forces are reallocated to the Resolute Support Mission to provide greater operational flexibility to the commander. These Marines are being reallocated to Afghanistan as part of a routine intra-theater movement of forces," said a statement from the NATO advise and assist mission.

There are less than 10,000 NATO troops currently in Afghanistan, though the Trump administration has considered sending additional troops as part of a strategy change. The most recent assessment from the Institute for the Study of War,released in February 2016, shows the situation has been deteriorating, especially since troop levels were lowered significantly after 2011.
