The military exercise Arctic Shield 2026 — an integral part of NATO's surveillance and presence activities called Arctic Sentry — involves the participation of over 400 military personnel from 11 allied nations, engaged in intensive training via land, sea and air in Greenland.

Joint Operations and Operational Domains

The maneuvers, coordinated by the Danish Defence Command and the Joint Arctic Command, exploit the ruggedness of the terrain to test interoperability between forces in extreme climate scenarios.

• Operational sites: While the focus of land-based activities concentrates in the vicinity of Narsarsuaq (in southern Greenland), the Dutch maritime forces operate in the fjord system around Kangerlussuaq, north of the Arctic Circle.
• Training specialties: Soldiers are training in land operations, parachute drops, advanced reconnaissance with drones, glacier climbing and advanced logistical support.
• Air and naval support: The Danish Defence Command provides helicopters, ships, medical and logistical support. Germany contributes with transport support and observers, while Poland and Slovenia participate as observers. In parallel, fighter jets from Denmark, Canada and the United States conduct joint air training over Greenland's skies.

The Contribution of Allied Nations

The exercise brings together regular forces, reserves, National Guard units and local specialists, highlighting strong multinational synergy:

“The operation is targeted and effective. There is excellent cooperation among everyone. Active duty soldiers, National Guard personnel, reservists, civilians and the local population are working together. It's fantastic.” — General Michael W. Hyldgaard, Chief of Defence of Denmark.

• Special forces and infantry:French infantry, Belgian drone units and Finnish special operations forces operate directly in the field and on the ice cap.
• Nordic National Guards: Units of the National Guard of Denmark, Norway and Sweden train side by side, integrating their tactics.
• Arctic experts: Canada participates by providing its own specialized expertise in the extreme conditions of the North and offering transport capacity.

This important deployment of forces confirms NATO's determination to defend its northern flank and consolidate strategic readiness in a geopolitically crucial area like the Arctic
