JBM-HH Garrison Exercises Emergency Response Capabilities

JOINT BASE MYER-HENDERSON HALL, Va. – The jarring sound of simulated gunshots suddenly echoed across the base, quickly followed by the loud wail of approaching sirens. Within minutes, first responders rushed toward the scene, navigating a highly chaotic environment complete with fake casualties and frantic bystanders seeking safety.

For a few intense hours, the scenario felt incredibly real. However, this was a carefully orchestrated test for the Joint Base Myer-Henderson Hall Garrison team as they successfully executed an active shooter Full-Scale Exercise (FSE) on July 29.

This major training event was specifically designed to test the military installation’s ability to rapidly respond to a serious threat. The overarching goal was to shorten the incident's duration, stop the threat, and immediately begin recovery operations.

The exercise served as a hands-on, practical test of the base’s emergency plans. It helps ensure that the dedicated military and civilian personnel who live and work on JBM-HH are constantly protected by a capable and synchronized emergency response team. Observed closely by evaluators from the Installation Management Command, the garrison team and external community partners performed exceptionally well under pressure. This realistic scenario challenged the base’s emergency network by testing how fast they could set up critical command centers.

Shortly after the simulated incident started, the team immediately stood up an Incident Command Post to act as the on-scene boss for local police and fire crews. Simultaneously, they activated the base Emergency Operations Center to handle the bigger picture, providing overall command, control, and resources.

The exercise also tested the activation of the Emergency Family Assistance Center. This center is vital for supporting affected workers and families with immediate information updates and crisis counseling. Additionally, a Recovery Working Group was activated to lead the post-incident rebuilding effort, ensuring the base had a concrete plan to safely return to normal operations as quickly as possible.

"Executing an FSE of this scale is an incredibly important part of our overall readiness," said Col. Keith P. Sandoval, JBM-HH Commander. "These large exercises build the necessary coordination and interagency trust required to respond to a real threat, protect our community, and safely navigate the aftermath of a critical incident.”

The event simulated an active shooter on the Henderson Hall side of the base, testing the specific duties of military police, local law enforcement, fire crews, and medical first responders. When initial reports were broadcast, responders converged on the scene to practice tactical movements and life-saving medical procedures. This dangerous phase required a highly coordinated team approach, validating how well security forces and medical teams work together when every second counts.

The exercise wrapped up with a simulated press conference to test public affairs teams under high-stress conditions. Providing timely, perfectly accurate information to the public is a vital piece of emergency management to prevent panic.

Following the tactical phases, the garrison transitioned into an After Action Review - a deep dive into what went right and what needs improvement. These crucial lessons will be used to refine local safety procedures, ensuring JBM-HH remains ready.

"The effectiveness of this FSE is a direct result of the intense preparation and smooth interoperability between our internal garrison directorates and our outside mutual aid partners," said Jonathan Dixon, Chief of Garrison Operations. "The speed at which we established command and control, addressed the simulated threat, and started our recovery operations met our key objectives. We demonstrated today that our operational framework is highly functional."

This major event serves as a strong reminder of the importance of continuous vigilance. While emergency services are the primary responders, the overall safety of Joint Base Myer-Henderson Hall also relies heavily on the situational awareness of its people.

Reporting suspicious activity and fully understanding standard emergency procedures are critical parts of the installation's defense. As the garrison implements these lessons learned, the base continues its work to remain a safe, secure, and resilient community, always capable of protecting its people and supporting its mission.
