Marine Corps launches Campaign – Alaska

The Marine Corps has announced “Campaign – Alaska,” a new Arctic-focused initiative that expands the service’s presence and training activity in the state. The effort combines a new Marine Rotational Force – Alaska, or MRF-Alaska, with a permanent Supporting Arms Liaison Team – Alaska, or SALT-Alaska.

Marine Corps leaders described the move as part of a broader effort to prepare forces for cold-weather and High North operations. The service said the initiative aligns with the 2026 National Defense Strategy, which identifies terrain across the Western Hemisphere, from the Arctic to South America, as important to homeland defense and strategic competition.

Rotational force to support Arctic training

MRF-Alaska will operate under Marine Forces Northern Command and is intended to provide persistent, multi-domain expeditionary training and experimentation in Alaska. The rotational task force will vary in size by season, reflecting the demands of Arctic operations.

The Marine Corps did not identify the specific location in Alaska where the rotational force will be based or which units will make up the first rotation. Sen. Dan Sullivan said the new force is a task-organized Marine Air-Ground Task Force designed to operate in extreme cold weather, austere terrain, and limited-infrastructure conditions.

Officials said the formation is intended to help prepare Fleet Marine Force units for Arctic missions while improving interoperability with joint and allied partners through exercises and training events.

Permanent detachment established at Joint Base Elmendorf-Richardson

Alongside the rotational force, Marine Corps Forces Reserve is establishing SALT-Alaska as a permanent detachment in the state. The team will come from the 6th Air Naval Gunfire Liaison Company and will be based at Joint Base Elmendorf-Richardson.

The detachment is intended to work closely with other U.S. military elements in Alaska and support coordination across joint operations. According to the Marine Corps, SALT-Alaska is expected to provide a persistent Marine presence in the state by fiscal year 2027 and help position the service for rapid expansion if required.

Marine Corps Forces Reserve said the move builds on its existing history in Alaska, where it has maintained a presence dating to 1985.

Shift in Arctic focus toward Alaska

Marines have trained in Alaska before, including participation in exercises such as Red Flag and Arctic Edge. Marine Raiders also took part in Arctic Edge earlier this year, while other Marine units have been involved in Kaiju Rain drills across the Pacific theater.

However, much of the Corps’ recent Arctic preparation has taken place in Europe. Earlier in 2026, about 3,000 Marines deployed to Scandinavia for NATO’s Cold Response 26 exercise. The new Alaska initiative indicates a shift toward a more sustained training and operational presence in the U.S. Arctic.

Part of a wider U.S. military Arctic posture

The announcement comes as the Defense Department continues to expand Arctic capabilities and infrastructure. Alaska already hosts a substantial U.S. military footprint, including missile defense facilities, major air assets, and the Army’s 11th Airborne Division at Joint Base Elmendorf-Richardson, which specializes in cold-weather operations.

Air Force units in the state also support North American Aerospace Defense Command missions, including aircraft intercepts in the Alaska Air Defense Identification Zone. Marine leaders said Alaska’s strategic value is increasing and that the new campaign is intended to provide the joint force with a combat-credible capability for homeland defense and power projection in the Arctic.
