Denmark deploys additional combat-ready troops to Greenland as part of Operation Arctic Endurance, a multinational military exercise accelerated and intensified in response to U.S. annexation threats. Major General Søren Andersen confirms that approximately 100 Danish soldiers have arrived in Nuuk, with similar numbers deployed to Kangerlussuaq, bringing the total deployment to several hundred personnel including the Chief of the Royal Danish Army, General Peter Harling Boysen.
Danish public broadcaster DR reports that troops have been ordered to combat readiness in case the United States attacks Greenland, and have brought contingency stocks of live ammunition. The Ministry of Defence confirms Danish troops would immediately respond to an invasion of Greenland with force. Chairman of the Defence Committee Rasmus Jarlov states Denmark would invoke NATO Article 5 if attacked by the U.S., adding that such an attack "would mean war with Denmark" and that retaliation would include deadly force.
Operation Arctic Endurance involves NATO allies including Sweden, France, Germany, Norway, the Netherlands, and Finland. The operation includes guarding critical installations, assisting Greenland police authorities, receiving allied troops, deploying fighter jets in and around Greenland, and conducting naval operations throughout 2026. Danish authorities announce the deployment may remain in Greenland for one to two years.
The combat posture represents an extraordinary defensive mobilization by a NATO ally against the alliance's traditional leader, reflecting the severity of the constitutional and diplomatic crisis triggered by Trump's territorial ambitions.
