U.S Special Operations Command North has formally unified all U.S. Special Operations Forces activities in Greenland under the overarching operational name, Operation Apex Indigo.

Conducted in close partnership with the Kingdom of Denmark and the Government of Greenland, Operation Apex Indigo provides an enduring framework to enhance extreme cold-weather survival, improve mobility in remote areas, and expand interoperability with fellow NATO Arctic nations.

“Our relationship with the Kingdom of Denmark is both enduring and essential to Arctic security,” said U.S. Army Col. Matthew Tucker, SOCNORTH commander. “Operation Apex Indigo strengthens our ability to work alongside Danish and Greenlandic partners, improve readiness in one of the world’s most demanding environments, and support collective deterrence across the Arctic.”

While Apex Indigo marks a new operational chapter, SOCNORTH operators are no strangers to the world’s largest island. Over several years of recurring engagement, U.S. SOF has systematically built out its Arctic capabilities alongside allied nations.

This progression began with Arctic Edge 23, continued through Arctic Edge 24 training with Danish, Norwegian, and British counterparts, and expanded through Arctic Edge 26 and the August 2026 inaugural mission of Operation Apex Indigo. The operation provides an enduring framework for SOF activity in Greenland focused on extreme cold-weather survival, remote-area mobility, and interoperability with Arctic allies.

“Operating in Greenland alongside our Danish and Greenlandic partners demands more than simply enduring the environment,” Tucker said. “It requires specialized skills, disciplined preparation, and the interoperability needed to operate effectively in austere Arctic conditions. That readiness strengthens collective deterrence and prepares our forces to respond to future security challenges.”

SOCNORTH employs small, specialized teams trained to operate in austere Arctic conditions. Their presence supports combined readiness, mobility, and interoperability alongside Danish and Greenlandic partners.

“Arctic defense requires an unmatched level of environmental experience and expertise,” said a Green Beret Detachment commander with 10th Special Forces Group (Airborne). “Danish Special Operations Forces bring extensive Arctic experience that is critical to our combined training and interoperability.”

Under Operation Apex Indigo, SOCNORTH will drive expanded activities across Greenland in lockstep with our Danish and Greenlandic allies. U.S. SOF will conduct recurring bilateral and multinational training alongside NATO allies to ensure special operations teams can integrate and operate effectively in the extreme conditions of the Arctic. This combined approach strengthens readiness, interoperability, and collective deterrence across the Arctic.

“Greenland’s vast distances and demanding conditions favor small, specialized teams that can operate with a deliberate, low-impact footprint,” Tucker said. “We work closely with Danish and Greenlandic partners to minimize disruption to local communities and the environment while building the readiness and interoperability required for Arctic security”
