386th AEW Joint Mass Casualty Exercise Published Sept. 25, 2025 By U.S. Air Force Senior Airman Mark Colmenares 386th Air Expeditionary Wing U.S. CENTRAL COMMAND AREA OF RESPONSIBILITY -- The base alert signal crackles and screams “Alarm Red!” You rush to the nearest bunker. After what seems like an eternity, you finally get the go-ahead to sweep the area — but to your surprise, there are wounded everywhere. What do you do? Canadian Armed Forces medics seek shelter in a bunker during a mass casualty exercise within the U.S. Central Command area of responsibility, Aug. 8, 2025. The training scenario simulated a large-scale emergency, beginning with a simulated ground attack, allowing personnel to practice initial response procedures and coordination with 386th Air Expeditionary Wing first responders.

First responders from the 386th Expeditionary Medical Squadron, 386th Expeditionary Civil Engineering Squadron and 386th Expeditionary Security Forces Squadron collaborated with U.S. Army combat medics from the 1st Battalion, 44th Air Defense Artillery Regiment, and medics from Canadian Armed Forces in a simulated emergency scenario in response to multiple casualties. Capt. Eric Juneau, Canadian Armed Forces medical officer, said the exercise was designed to test real-world readiness. “We’re doing an exercise to simulate a mass casualty event in order to help prepare both the Canadian personnel and the American personnel on how to respond — from first aid in the field all the way up to hospital care,” Juneau said. He added that the training helps both nations identify gaps before a real event occurs. “The threat in this region can evolve rapidly and unpredictably,” Juneau said. “By practicing the unique procedures of a mass casualty event, we can be ready for when these stressful situations occur and figure out what areas went well and what areas need some work from a training and resource perspective.” Medics from the 386th Expeditionary Medical Squadron and the Canadian Armed Forces treat a simulated patient during a mass casualty exercise within the U.S. Central Command area of responsibility, Aug. 8, 2025.

Once cleared, medics and firefighters assessed, prioritized and treated more than 20 mock patients, who were sorted according to the severity of their injuries. Patients were transported to the medical facility for further care. U.S. Air Force Senior Airman Taylor Lineburg, 386th EMDS medical technician and exercise coordinator, emphasizes the interoperability the scenario brought between multiple units, including security forces, firefighters, Canadian medics and Army combat medics. “The expectation was mostly about response times and how everyone would react,” Lineburg said. “You can put people in a classroom all day, but experience is the actual test — how are you going to respond whenever it actually happens?” Lineburg reinforces the importance of repetition these trainings can bring to real-world scenarios. “We needed everybody to be up to speed and to have a similar experience so whenever this actually happens, nobody’s freezing or blanking on what to do,” Lineburg said. U.S. Air Force Senior Airman Baichen Mei, 386th EMDS medical technician, emphasizes the sense of urgency at the casualty collection point after fire crews cleared the area.
