About 90 members of the California National Guard and over dozen military vehicles like Humvees are helping protect immigration officers Monday as they carry out a raid in a Los Angeles park.

California National Guard soldiers arriving in Humvee military vehicles backed a Monday sweep of a park in a neighborhood of Los Angeles heavily populated by immigrants, according to L.A. Mayor Karen Bass.

“That runs the gamut from making arrests, investigating crimes, and doing police work, all the way up to guarding prisoners or running courts,” says Daniel Maurer, an Army JAG until 2024 who also taught law at West Point and at the Judge Advocate General’s School in Virginia.
