Two hundred Marines from San Diego’s Camp Pendleton have been temporarily deployed to the U.S.-Mexico border, according to media outlets, to support the Department of Homeland Security and the U.S. Border Patrol as they expect a rush of migrants after Title 42—which was put in place limiting asylum seekers from entering the U.S. during the COVID pandemic—expired just before midnight May 11.

The Marines are part of 1,500 active-duty troops that will assist border patrol agents for at least 90 days with ground detection monitoring, warehouse support, and data entry, Pentagon Press Secretary Air Force Brig. Gen. Pat Ryder said during a May 9 press conference.

“The troops will not be conducting any type of law enforcement activities,” he said.

About 2,500 members of the National Guard have already been deployed at the border.
