English: Pictured are Shore Reconnaissance Team (SRT) from 30 Commando’s Surveillance and Reconnaissance Squadron (SRS) practice surveying beaches to identify appropriate landing points for follow-on forces during Winter Deployment 21 in the Arctic. Training took place as part of 3 Commando Brigade's Winter Deployment 21 which sees more than 600 personnel undertaking training in Arctic conditions. Royal Marines have deployed to the frozen Arctic for many years, to conduct their annual cold weather training. The Commandos are 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.
