US special-operations forces ventured to Alaska in February to train for Arctic warfare.

Their trip reflects the US military's increasing focus on the Arctic, which is growing more accessible.

The US isn't the only country with an interest in Arctic security, and US operators aren't alone there.

With near-peer warfare back on the agenda, US special operators are focusing their training on environments where they are highly likely to find themselves engaged.

The frigid Arctic is one of those environments, and Navy SEALs and Special Warfare Combatant-Craft Crewmen operators, Green Berets and elite aviators from the Army, and Air Commandos recently spent almost a month training in it.

From late February to mid-March, conventional and special-operations units got together for Arctic Edge 22, the US military's flagship Arctic warfare exercise.

Operators from across the US special-operations community joined conventional forces and local, state, and federal law-enforcement in Alaska.
