Denmark has launched its largest military exercise since the Cold War, with more than 6,500 volunteer soldiers taking part in a nationwide operation aimed at strengthening preparedness against hybrid threats and sabotage.

According to Danish broadcaster DR, the exercise, named "Bluetooth" (Blåtand), comes after Denmark's Defence Intelligence Service warned that Russia could intensify hybrid warfare activities targeting the country.

The four-day exercise, which runs from 1 to 4 October, is being conducted across Jutland, Funen and the surrounding islands with the participation of personnel from the Danish Home Guard's army, navy and air force units. It is regarded as the largest exercise of its kind since the Cold War.

Focus on critical infrastructure and crisis response

Unlike conventional military drills held in training areas, much of the exercise is taking place in towns and cities, where troops are rehearsing operations under realistic conditions.

Soldiers are training to protect critical infrastructure, conduct patrols, respond to sabotage and hybrid attacks, support ground-based air defence units and assist police and other civilian authorities during potential crisis situations.

Danish residents are expected to see armed Home Guard personnel and military vehicles in public areas throughout the exercise. Authorities stressed that the activities are part of a planned drill and urged the public not to be alarmed.

Home Guard Commander Major General Gunner Arpe Nielsen said the changing security environment requires volunteer forces to train under realistic conditions so they can respond quickly and effectively if Denmark faces a serious crisis or conflict.

The exercise is scheduled to conclude on Sunday, after testing the Home Guard's ability to respond rapidly to a range of security scenarios across the country.(ILKHA)
