Defense Secretary Mark Esper has authorized up to 5,500 servicemembers to continue missions along the U.S.-Mexico border in fiscal year 2020.
Esper approved the request last week from the Department of Homeland Security to extend the mission, Lt. Col. Chris Mitchell, a Pentagon spokesman, confirmed Wednesday
Troops will provide infrastructure support, operational support, detection and monitoring support and air support, Mitchell said. This is similar to the work that officials have described is now being done by troops along the border
