NATO on Wednesday unveiled a new military coordination effort dubbed “Arctic Sentry,” aimed at strengthening security cooperation in the High North, just weeks after U.S. President Donald Trump heightened tensions within the alliance by threatening to annex Greenland.

Arctic Sentry will initially serve as a unifying label for existing national military exercises in the Arctic region, including Denmark’s Arctic Endurance and Norway’s Cold Response drills. The initiative does not constitute a new NATO military operation, nor does it involve permanent troop deployments under a NATO banner.

“What is really new about it is that for the first time now we will bring everything we do in the Arctic together under one command,” NATO Secretary-General Mark Rutte told reporters in Brussels. He said the move would enable the alliance to better identify and address security gaps in the region.

Rutte cited Russia’s increased military activity and China’s expanding interest in the Arctic as key drivers behind the decision. Coordination of Arctic Sentry activities will be handled through NATO’s U.S.-based command in Norfolk, Virginia.

U.S. Air Force Gen. Alexus Grynkewich, NATO’s Supreme Allied Commander Europe, said the initiative underscores the alliance’s commitment to stability in a strategically significant and environmentally challenging region.

As part of the broader effort, the United Kingdom announced it will double its troop presence in Norway to 2,000 over the next three years. Some forces will participate in Exercise Lion Protector in September. France, Germany and Denmark have also pledged involvement, though troop numbers remain unclear.

European allies hope Arctic Sentry will refocus NATO on shared security priorities, particularly Russia’s war in Ukraine, following diplomatic strains over Greenland, a semiautonomous Danish territory.
