San Diegans who live or work near Marine Corps Recruit Depot San Diego should brace for a loud and very visible show of emergency preparedness on Wednesday, when the base runs a full-scale active-shooter training exercise during normal business hours, military officials said.
People in the area can expect booming emergency alerts from speaker towers, a surge in military and civilian emergency vehicles, and temporary security measures that could briefly slow traffic or limit access to the base. All gates at MCRD are set to be closed for a short window between 9 a.m. and 10 a.m., while response agencies move in and out to test how well emergency protocols hold up under pressure. The depot sits just off Midway Avenue near San Diego International Airport, so nearby residents and motorists may hear announcements and see stepped-up activity on and around the installation, according to FOX 5 San Diego.
What neighbors can expect
Those in the neighborhoods surrounding the base may hear mass-notification messages blaring from speaker towers and could see ambulances, fire engines and military police racing around the depot as part of the scenario. Officials are stressing that the exercise is a training event, not an actual emergency, although they plan to keep things realistic so teams can rehearse how they would coordinate with local agencies in a true crisis.
If you notice suspicious activity that appears unrelated to the exercise, you are urged to call 911. For information specific to the drill itself, officials say to monitor official MCRD channels for updates.
Why the drill matters
Full-scale active-shooter drills give base and local responders a chance to run through communications, medical triage and lockdown procedures in conditions that feel closer to the real thing. Similar exercises across Marine Corps installations have been used to spot weak points and tighten coordination between military police, fire services and emergency medical teams, as detailed by Ready Marine Corps. Training of this kind is a routine piece of installation readiness and force-protection planning.
MCRD officials say they will post updates on their official social-media accounts and are asking the public for patience while the exercise is underway. The initial advisory about the drill was reported by FOX 5 San Diego. For the latest details, residents are encouraged to follow MCRD social channels or local news outlets, and to call 911 if they believe they are seeing an actual emergency.
