Senior-level civil and military experts, including U.S. Army Col. Michael Firmin, director of the Education, Training and Evaluation Department at the NATO Joint Chemical, Biological and Radiological Defence Center of Excellence located in Vyskov, Czechia, receive a briefing from Katrien VanHamme, exercise director for Exercise Bulgaria 2025 in Montana, Bulgaria. Over 1,000 military and civilian emergency responders from 18 participating nations trained together Sept. 7-12, practicing civilian-military interoperability during the crisis management exercise hosted by NATO’s Euro-Atlantic Disaster Response Coordination Centre and the Bulgarian Ministry of Interior. The exercise was one of the largest and most complex disaster response exercises in the world this year with soldiers, scientists and first responders working together to respond to a simulated earthquake in this small mountain town tucked away in the northwest corner of Bulgaria not far from the borders of Romania and Serbia.
