Sweden's armed forces have rehearsed the grim logistics of mass military burials as part of Aurora 26, the country's largest national exercise in decades. The drill, which ran from late April to mid-May 2026, involved around 18,000 troops from 13 nations and marked a significant step in Sweden's transition from Cold War neutrality to active NATO membership.
According to a peer-reviewed account in the journal Frontiers in Psychiatry, the mortuary affairs component used more than 500 mannequins and body bags to simulate fallen service members—a scale not attempted in Sweden since the early 1950s. Over 300 military personnel took part, alongside the Church of Sweden, the Swedish Tax Agency, and the country's conscription agency.
Testing the full chain of war dead handling
The exercise tested every step of the process: recovery of bodies, identification, notification of allied embassies and the International Committee of the Red Cross, and burial with military honours. The commanding officer told researchers: "I am proud to have been part of this. The last time this was practiced was, I believe, in 1952, so I am proud to have contributed."
A military chaplain reflected on the visual impact, saying that seeing dozens of body bags lined up made the abstract reality of war casualties suddenly concrete. Defence trade outlet Defence24 reported it was the first time the process had been rehearsed jointly by every relevant institution.
Officials framed the planning as a matter of morale and institutional readiness rather than a prediction of casualties. A military physician noted that after the exercise, personnel would need "a major adjustment" in how medical teams are resourced for mass-casualty scenarios, while another soldier told researchers the exercise gave them "a clearer understanding of the consequences of war."
Planning for the worst scenario
Separately from the exercise itself, the Church of Sweden, which remains the country's statutory burial authority, has long been instructed to plan for burial capacity equivalent to 5% of the national population—roughly 500,000 people. That figure is a Cold War-era civil defence benchmark covering both military and civilian deaths nationwide, not a forecast tied to Aurora 26 or any specific casualty estimate.
Asked about the planning, Jan-Olof Olsson of Sweden's civil defence agency told Le Monde it does not mean authorities expect that many victims, but that "to plan, we need an estimate."
The drill sits within a wider pattern of Baltic states and NATO's northern flank rehearsing worst-case scenarios as tensions with Russia persist. Aurora 26 also featured Ukrainian drone specialists training NATO troops in counter-drone tactics, and forces from the US, Netherlands, France, Poland and other allies operating across southern Sweden, Gotland and the Baltic Sea.
This exercise comes as European defence spending and preparedness are under renewed scrutiny. EU defence ministers have recently convened to address hybrid threats from Russia, while Switzerland plans to field a drone battalion by 2028 as part of a broader European rethink of defence. Sweden's own defence modernisation includes a €4.3bn frigate deal with France, underscoring the country's commitment to collective security.
