Early Saturday morning, Los Alamitos residents who live next to the Joint Forces Training Base woke up to the sounds of National Guard service members participating in drills, learning techniques they will presumably need on the streets of southern California.
In a federally authorized effort that reportedly includes approximately 4,000 National Guard troops and 500 U.S. Marines, the base has become the hub of an ongoing effort to round up undocumented aliens and deport them.
Accordingly, the “federalized” effort has since put the base in lockdown mode, as routine access to non-military personnel is no longer authorized, according to U.S. Army public affairs
“Due to the current force protection posture, base officials made the decision to limit base access,” she said to Event News Enterprise in an email. In addition, since the email, National Guard forces along with other armed forces and key installations have been placed on high alert since the bombings in Iran.
The entire, massive base, property, and the majority of structures that sit on it, is owned by the federal government, even if an ongoing agreement with state officials allows the California National Guard to command the base.
In addition, she said that while 40th Infantry Division Brigadier General Robert Paoletti is currently in command of the base, he is simply “covering the duties as base commander in Lt. Col. Fox’s absence, who is traveling.” Sources say Lt. Col. Fox is expected to be back on base in the next couple of weeks.

Temporary structures, part of the deployment of California Army National Guards and United States Marine Corps by President Donald Trump to Los Angeles in response to the protests against Federal immigration raids, are seen at Joint Forces Training Base Los Alamitos in Los Alamitos, Calif., Friday, June 20, 2025.
In a brief telephone interview this week with Lt. Col. Fox, who was visiting the U.S. Army War College in Pennsylvania, he confirmed the changes ongoing at the base and said the base transformation will likely stay in place for the “foreseeable future.”
Col. Smith, in her email, confirmed Lt. Col. Fox’s assertion.
“We will be here until the conclusion of the mission which was originally slated for 60 days,” she said.
Moreover, Lt. Col. Fox said he remains the commander of the base and plans to return in a few weeks.

Meanwhile, the city’s traditional fireworks display on the base, which drew a record 12,000 spectators last year, has become a casualty of sorts, as the limited access will not permit visitors on the base.
The City of Los Alamitos, meanwhile, issued a statement acknowledging the base’s temporary transformation’s limited access, saying the fireworks display will go on, but only as a livestream.In addition, visitors to JFTB before the lockdown said they saw thousands of troops and military vehicles on the base, including vehicles labeled as the Bureau of Immigration and Customs Enforcement (ICE).
It is not known if ICE agents are among those who have moved onto the base as the deployment continues, while massive white structures and temporary buildings have been constructed on portions of the base that parallel residential streets of Los Alamitos.

While ENE was not allowed on the base to take photos, portions of the new construction are visible from some of the public streets adjacent to the new construction.
On Saturday, troops were visible from this vantage point, practicing drills in formation. While there are 4,000 California National Guard troops involved with the deployment, it was not disclosed how many of them are currently living on the base.
The 500 U.S. Marines assigned to the deployment reportedly trained nearby at the Seal Beach Naval Weapons Station.
Meanwhile, citizens, businesses, and nonprofit organizations have reacted to the round-up in a variety of ways, quickly assembling a variety of methods, including a major workshop, to explain individuals’ rights to citizens.
