A battalion of roughly 700 U.S. Marines from the 2nd Battalion, 7th Marines (1st Marine Division) at Twentynine Palms, California, has been mobilized to Los Angeles amid widespread protests over recent ICE immigration raids. This unprecedented activation supplements the nearly 4,000 National Guard troops already in the city, marking the first in‐state use of Marines since the 1992 LA riots. Below is a comprehensive breakdown of what’s happening in LA, why Marines are involved, and the legal framework governing domestic military deployments.
Why Are Marines Being Deployed to Los Angeles?
Following large‐scale protests in neighborhoods like Paramount, Compton, and downtown LA—sparked by aggressive ICE operations that arrested over 118 individuals—President Trump authorized National Guard troops to “protect federal property and personnel.” When unrest persisted, a full 700 Marines battalion was mobilized to provide additional coverage under U.S. Northern Command directives .
Augmentation of Guard Forces: The Marines are tasked with bolstering the Guard’s presence at critical federal sites, such as the Metropolitan Detention Center and City Hall .
Protection, Not Policing: Without invocation of the Insurrection Act, Marines cannot make arrests or conduct law enforcement; their role is strictly defensive and supportive .
Rationale: Officials say the additional troops ensure “continuous coverage” for federal personnel amidst protests that have at times turned violent .
Have the Marines Ever Been Deployed Domestically?
Yes. The last major domestic deployment of Marines occurred during the 1992 Los Angeles riots, when Marines supported civil authorities after the verdict in the Rodney King case sparked citywide disorder . Since then, Marines have generally remained focused on overseas missions, with only limited roles in border support under Operation Guardian Shield. This current mobilization represents a significant escalation in the military’s domestic role.

Can Marines Be Deployed in the United States?
Under Title 10 U.S. Code, active‐duty military forces—including the Marines—are barred from performing civilian law enforcement unless the president invokes the Insurrection Act. In this situation:
National Guard (Title 32): Already deployed by presidential order, typically under state control but federalized in LA without governor consent.
Active Duty Marines (Title 10): Activated to support, but limited to protecting federal entities; any direct law enforcement (e.g., arrests) would require Insurrection Act authorization .
Legally, this mirrors past uses of the Insurrection Act for insurrections, though it has not been formally invoked here. Instead, Marines act under domestic support provisions to aid civil authorities.
What Are Marines Doing on the Ground?
While precise orders remain classified, sources indicate Marines will likely:
Establish Perimeter Security around federal buildings and detention centers.
Assist with Crowd Control in tandem with National Guard units, without making arrests.
Provide Rapid Reaction Forces ready to respond to escalating unrest .
Their presence is as much political signaling—a “show of force”—as it is operational, aiming to deter further violent confrontations.
What’s Going On in LA? Violent Riots Continues in The Name of Peaceful Protest
ICE Raids and Backlash
Federal agents conducted sweeping ICE operations across LA last week, detaining alleged criminals and undocumented immigrants at workplaces and homes. Community groups decried the raids as indiscriminate, leading to mass demonstrations that occasionally turned violent, with windows smashed and vehicles set ablaze .
Local vs. Federal Standoff
Governor Newsom condemned the federal troop deployments as “unwarranted” and “unprecedented,” challenging both National Guard and Marine mobilizations without state approval .
Mayor Bass called the Marines’ involvement a “chaotic escalation,” urging peaceful protest and dialogue rather than militarized responses .
National Guard Numbers
By Monday, roughly 1,700 Guard members were operational, with an additional 2,000 ordered over the weekend. The 700‐strong Marine battalion further swells federal forces to nearly 4,400 personnel in the LA area .
Historical Riots In LA
The use of armed forces in American cities is rare and highly regulated:
1992 LA Riots: Marines and other federal troops restored order after four days of unrest.
Insurrection Act: Last invoked during the 1992 riots; otherwise reserved for extreme threats to federal authority.
Posse Comitatus: A principle restricting military involvement in domestic enforcement, unless overridden by specific laws like the Insurrection Act.
Experts caution that deploying active‐duty troops risks blurring lines between military and police, raising civil liberties concerns.
With protests expected to continue, the role of Marines in LA remains under close watch:
Potential Activation of the Insurrection Act could grant Marines arrest powers—though no indication exists that the administration plans this move.
Community Impact: Continued militarization may fuel further unrest or alternatively serve as a deterrent.
Legal Challenges: California officials have threatened litigation to block unauthorized federal force deployments within the state.
For now, the primary mission is clear: protect federal property and personnel while maintaining a support role to the National Guard, preserving the boundary between military and law enforcement.
