Thousands of troops will be spending the holidays at the US-Mexico border supporting border patrol agents as they deal with the arrival of large migrant caravans.
Secretary of Defense Jim Mattis has approved a Department of Homeland Security request that will extend the mission for active-duty troops at the border into 2019, according to multiple news outlets. The “border support” mission, previously known as Operation Faithful Patriot, has officially been extended past the original Dec. 15, 2018 end date to Jan. 31, 2019.
There are currently 5,600 active-duty troops serving at the US-Mexico border. These service members are in addition to the 2,100 National Guard personnel that deployed to the border in 2018. Troops at the border spent Thanksgiving there, and now it seems they will also be spending Christmas and New Year’s at the southern border.

It is unclear how many troops will be affected by the extension. Earlier reports suggested that only around 4,000 troops would remain at the border.
US military personnel at the US-Mexico border started the deployment erecting barriers and running razor wire, but following a clash near the San Ysidro point of entry, during which border agents used tear gas and other means to disperse migrants that rushed the border, some troops have begun conducting riot control training in coordination with Customs and Border Protection.
