After days of fiery protest against federal immigration raids, Los Angeles residents and officials braced for the arrival of hundreds of U.S. Marines on Tuesday in what some called an unprecedented and potentially explosive deployment of active-duty troops with hazy mission objectives.
As Trump administration officials vowed to crack down on “rioters, looters and thugs,” state and local officials decried the mobilization of 700 troops from the Marine Corps Air Ground Combat Center in Twentynine Palms, calling it a clear violation of law and civility. L.A. Mayor Karen Bass even likened the deployment to “an experiment” that nobody asked to be a part of.
According to the U.S. Northern Command, which oversees troops based in the United States, the Marines will join “seamlessly” with National Guard troops under “Task Force 51” — the military’s designation of the Los Angeles forces. The Marines, like the Guard, they said, “have been trained in de-escalation, crowd control and rules for the use of force.”
Air Force Gen. Gregory Guillot told The Times on Tuesday that the Marines in Los Angeles were limited in their authority, deployed only to defend federal property and federal personnel. They do not have arrest power, he said.
“They are not law enforcement officers, and they do not have the authority to make arrests,” Guillot said. “There are very unique situations where they could detain someone ... but they could only detain that person long enough to hand it off to a proper law enforcement official.”
But military experts have raised practical concerns about the unclear parameters of the Marines’ objective. They also warn that sending in Marines without a request from a governor — a highly unusual step that has not been made since the civil rights era in 1965 — could potentially inflame the situation.
U.S. Marines are trained for overseas conflict zones, with deployments in recent decades in Iraq, Syria and Afghanistan. But the roles they have played in those nations — including providing artillery support to coalition forces fighting against Islamic State militants and advising and training local security forces — are quite different from what they might face as they confront protesters in Los Angeles.
“Marines are trained to fight, that’s the first thing they’re trained to do,” said Jennifer Kavanagh, director of military analysis at Defense Priorities, a military research group. “So I think you do have a little bit of mismatch in skills here.”
“In a crisis, when they’re forced to make a snap decision, do they have enough training and experience to make the one that de-escalates the situation rather than escalates it? I think that’s a question mark,” Kavanagh said.
Hours after Defense Secretary Pete Hegseth told congressional lawmakers Tuesday that the mobilization of troops to Los Angeles to curtail protests would cost $134 million, President Trump told U.S. Army troops at Ft. Bragg in North Carolina that he deployed thousands of National Guard troops and hundreds of Marines “to protect federal law enforcement from the attacks of a vicious and violent mob.”
But city and state officials have repeatedly said that troops are not necessary to contain the protests.
On Monday night, California Gov. Gavin Newsom called the deployment of Marines “a blatant abuse of power” and filed a lawsuit seeking to overturn the deployment.
Los Angeles Police Chief Jim McDonnell warned that — “absent clear coordination” — the prospect of Marines descending on Los Angeles “presents a significant logistical and operational challenge for those of us charged with safeguarding this city.”
However, Guillot said coordinating among different agencies “hasn’t been a challenge to us at all.”
“I think people understand that we’re there for a very specific purpose,” he said. “We’re very highly trained, professional and disciplined, and people have been very cooperative so far.”
By Tuesday afternoon, all 700 Marines had arrived in the Greater Los Angeles area, Guillot said. At least one convoy of U.S. Marine vehicles from Twentynine Palms had arrived at Orange County’s Naval Weapons Station Seal Beach under police escort.
The mobilized Marines and National Guard troops will be stationed in facilities across the region, including Seal Beach, Los Alamitos and a number of National Guard armories, Guillot said. He didn’t provide further details.
Over the last few days, National Guard members have already been stationed at a few federal buildings and have accompanied Immigration and Customs Enforcement agents on missions, Guillot said. He expects Marines will be mobilized on the ground Wednesday, if not Tuesday evening, after wrapping up final training.
It is rare for U.S. Marines to be sent to an American city. The last time they were deployed in the U.S. was after riots broke out in Los Angeles in 1992 after the acquittal of four LAPD officers who were recorded beating a Black motorist, Rodney G. King.
Back then, President George H.W. Bush acted at the request of California Gov. Pete Wilson and Los Angeles Mayor Tom Bradley after what The Times described as “three days of the worst urban unrest in Los Angeles history.”
Deploying Marines to Los Angeles is not only a dramatic escalation of events, but also potentially illegal, according to Abigail Hall, a defense scholar and senior fellow at the Independent Institute, a nonprofit think tank based in Oakland.
Bringing in the Marines to L.A., she said, violates the Posse Comitatus Act, an 1878 law enacted after the Civil War, which forbids active-duty federal forces to provide regular civilian law enforcement unless authorized by Congress or the president invokes the Insurrection Act.
Trump has yet to invoke the Insurrection Act.
“I don’t see any way that this is not a direct violation of the Posse Comitatus Act,” Hall said. “We’re not at war, we’ve not invoked the Insurrection Act of 1807 — and even if we did, that’s what the National Guard is for. It’s not what the Marines are for.”
Kavanagh didn’t comment on the deployment’s legality, but called it unprecedented in modern times. She worried that could make its mission and parameters unclear for troops.
The last time the military was deployed without a governor’s request or approval, military experts said, was to facilitate court-ordered desegregation in Southern states during the civil rights movement in the 1960s.
Kori Schake, senior fellow and director of foreign and defense policy studies at the American Enterprise Institute, said the Trump administration appeared to be trying out a new way to get around the restrictions on domestic law enforcement by the American military.
“The authority the president is claiming is his constitutional authority under what’s called the Take Care clause ... he’s claiming the federal responsibility to protect federal agents and federal property operations. That authority has never been tested in court.”
Such an approach, Schake said, was fraught with more than legal risk.
“If violence burgeons, tempers are running high, the Marines are armed, this could spiral out of control,” Schake said.
The L.A. deployment, Kavanagh said, could also be a jarring mission for Marines who signed up to go abroad and defend America’s freedom — and instead are facing off with fellow citizens.
“Does everyone know the rules of engagement?” Kavanagh asked of the L.A. mission. “Are they clear?”
She also worried that the troops deployed to L.A. are likely to have some of the most limited experience. Guard members are not full time and undergo less frequent training, and Marines retain the youngest service members of all the military branches. Nearly three-quarters of active-duty enlisted members of the Marine Corps are 25 or younger, according to a 2022 Department of Defense report. The average age is 24, compared with 27 for the Army and 28 for the Air Force.
Schake, however, pointed out that although Marines may be the youngest cohort in the military, they are well trained in de-escalation tactics.
“The wars that the United States has been fighting for the last 25 years have required incredible discipline on the use of force by the military in Afghanistan and in Iraq in particular, so they are trained for de-escalating conflict,” Schake said. “I think actually, it’s quite possible they’re better trained at de-escalation of violence than the police forces are.”
In that sense, Schake said she was less worried about violence on the streets than about “creeping authoritarianism.”
“The way the president, that Homeland secretary, the secretary of Defense, the White House press spokesman are talking is incendiary and reckless,” Schake said.
“They’re calling the city of Los Angeles — where 1 in 40 Americans live — a hellscape, and everybody in the city a criminal. They’re describing protests that are really peaceful as an insurrection. And that’s a very reckless thing to do in a difficult situation.”
