‘Apocalypse Now’–Style Drills Rattle SoCal Neighborhoods — FBI Says Training Could Continue For Two Years

Military-style night drills — including helicopters, simulated gunfire and flash-bang grenades — startled residents across Southern California this week, with exercises reported in Pasadena, Irvine, Long Beach and Industry. Federal officials say large-scale tactical training may continue across the region for up to two years as agencies prepare for a slate of major international events.

Military helicopters, simulated gunfire and flash grenades rattled Pasadena, Long Beach and other suburbs this week.

What Happened

Late-night tactical operations were staged at multiple locations, most visibly at the former St. Luke Medical Center on Washington Boulevard in Pasadena and near Alton Parkway and Irvine Boulevard in Irvine. Local officials posted social media alerts after residents reported seeing helicopters, tactical personnel and loud explosions that resembled urban combat scenarios.

Why The Training Is Underway

Federal and local law enforcement agencies say the exercises are part of routine preparedness work involving specialized teams such as SWAT, bomb technicians, dive teams and crisis negotiators. Officials have linked the uptick in large-scale drills to preparations for several upcoming international events in the region, including the FIFA World Cup (June 11–July 19), the Super Bowl and the Olympic Games.

“We train on a regular basis… With the upcoming FIFA Games, upcoming Super Bowl, and upcoming Olympics, there may be additional training with additional partners, but we conduct training on a regular basis,” FBI spokesperson Laura Eimiller told the Orange County Register.

Public Reaction and Local Concerns

The timing and limited advance notice for some exercises drew criticism. Several cities say they received only hours' notice before drills began, prompting a surge of calls to city halls and police departments and leading officials in Pasadena to request fuller briefings on the scope and objectives of the operations.

In response to strong local reactions, the FBI said it is considering broader public outreach, including social media notices and community alerts to let residents know when and where training activity may be increased in connection with special events.

Context And Speculation

The drills have also sparked public speculation about shifting federal priorities and even preparation for urban warfare scenarios. Commentaries have pointed to a prior remark by former President Trump — made at a gathering of senior military figures — about using domestic cities for military training, which some residents cited as fueling concern. Officials emphasize that current exercises are law-enforcement-led preparedness activities, not military occupation or permanent deployments.

Some cities reportedly received only limited information before the operations, forcing officials to notify residents just hours before the drills began. ON SCENE TV

What Residents Should Know

Officials recommend residents follow local government social channels for official notices, avoid spreading unverified claims on social media, and contact local police or city hotlines if they see suspicious activity. Agencies conducting training have said they will increase public messaging to reduce confusion and improve safety for both participants and bystanders.

As Southern California prepares to host large international events and the influx of visitors they bring, officials say continued joint training is intended to strengthen coordination and response capabilities across federal, state and local partners.
