As of Wednesday, about 2,800 service members were deployed to the Los Angeles region, including 2,100 National Guard troops and 700 Marines, who have just completed training, according to a status update from U.S. Northern Command.

The Marines are expected to be serving alongside National Guard troops within the next 48 hours, the command said.

The Marines received training in de-escalation and crowd control among other things, according to the status update.

Both Marines and National Guard troops are serving as part of Task Force 51 under what's known as Title 10 status -- to protect federal personnel and federal property.

"They can and have accompanied ICE on missions, but they are not a part of the operations," according to the status update, referring to Immigration and Customs Enforcement. "Title 10 forces do not do law enforcement functions. They protect; they don't participate."

The troops may "detain an individual in specific circumstances such as to stop an assault, to prevent harm to others, or to prevent interference with federal personnel performing their duties." However, the troops are required to then transfer custody to the appropriate civilian law enforcement personnel.
