Royal Marines have deployed to the frozen Arctic for many years, to conduct their annual cold weather training.
The Commandos are currently in the North of Norway learning to be winter warriors conducting Arctic survival training in bitterly cold temperatures.
The conditions are harsh around 200 miles inside the Arctic Circle, where the sun barely rises and temperatures plummet to below -30C.
The Elite Royal Marines must be prepared to deploy anywhere in the world at a moment’s notice. That includes the most extreme climates known to man, including Arctic, jungle and desert.
