The Pentagon is sending 200 Marines to Florida to assist the Department of Homeland Security’s Immigration and Customs Enforcement with administrative work, U.S. Northern Command announced Thursday.

The Marines, based out of North Carolina and part of Marine Corps Air Station New River’s Marine Wing Support Squadron 272, will help “with critical administrative and logistical capabilities at locations as directed by ICE,” according to a news release from the combatant command.

“These Marines are the first wave of U.S. Northern Command’s (USNORTHCOM’s) support of this ICE mission,” reads a NORTHCOM statement.
“Other support locations will include Louisiana and Texas. Service members participating in this mission will perform strictly non-law enforcement duties within ICE facilities. Their roles will focus on administrative and logistical tasks, and they are specifically prohibited from direct contact with individuals in ICE custody or involvement in any aspect of the custody chain.”

It’s unclear where the Marines will go and whether they will support ICE’s new detention facility in Florida known as “Alligator Alcatraz.” The facility, located in Ochopee, Fla., opened earlier this week and is part of the Trump administration’s ongoing effort to detain and deport illegal immigrants.
