The normally quiet harbour of Holmsund outside Umeå this week became the stage for one of the Nordic region’s most complex military training operations. Some 200 soldiers and specialists from across Scandinavia gathered to practice responding to an explosive incident involving highly corrosive chemicals—an exercise designed to test how quickly and effectively Swedish and allied forces can confront extreme threats.
The scenario set for the exercise was daunting: an exploding bomb inside a shipping container that released a dangerous chemical agent. Units from Sweden, Norway, Denmark, and Finland worked hand-in-hand with emergency services from Västerbotten, conducting rapid response drills under the framework of Sweden’s total defence concept, which integrates civil and military resources in crisis scenarios.
Training for Today’s Threats
“The conflicts in our neighbourhood show that unconventional weapons remain a real possibility,” said Per Nilsson, Sweden’s deputy army chief, who oversaw the drill. “Russia has the capability to use chemical weapons, and while it is not clear whether such weapons have been deployed, our job is to prepare for the uncertainty.”
The training focused on mastering CBRN defence—countering chemical, biological, radiological, and nuclear threats—a field that has become a top priority for both NATO allies and partner nations. Soldiers in protective gear practiced decontamination, casualty evacuation, and explosive threat management under harsh simulated conditions.
Allied Eyes on Sweden
The exercise attracted significant international interest. Observers from France and the United States joined Nordic forces in Umeå to study how Scandinavia prepares for high-stakes scenarios at its key ports and energy hubs.
“My team and I are working against CBRN and nuclear attacks, so I’m here to observe and learn how others approach it,” explained Major Andrew McLure of the New York National Guard, adding that Sweden’s coordination between military and civil authorities “offers valuable lessons.”
Realism on the Ground
To increase the intensity of the training, around 20 Swedish conscripts were cast as civilian casualties. Wearing fake wounds and staged injuries, they created a chaotic frontline atmosphere as they were rescued, decontaminated, and treated by medics under pressure.
“It was very exciting to lie there and scream, be dragged across the ground, carried on a stretcher, and taken care of—it felt real,” said 19-year-old Elsa Magnusson, one of the extras in the drill.
Strengthening Nordic Security
The Holmsund exercise highlights the deepening security cooperation within the Nordic region at a time of growing instability along Europe’s eastern flank. By practicing together in realistic scenarios, Sweden and its partners are reinforcing their readiness against crises that could cross the boundary between conventional and unconventional warfare.
With Umeå and other northern ports serving as strategic gateways for military logistics and civilian trade, the ability to neutralize a chemical or explosive attack has become more than just a drill—it is now a cornerstone of deterrence and defence across the Nordic region.
