It is all part of the new Arctic strategy, Royal Navy submarines will spend more time under the ice, from 2020 the UK will begin using the new P8 Poseidon maritime patrol aircraft.
For the Royal Marines deployed to Norway, Arctic warfare training is taking longer than expected due to the weather conditions, with temperatures reaching lows of -30°c.
Five weeks into their Arctic warfare training, Charlie Company have progressed from the basic survival course.
Around 200 miles inside the Arctic Circle, they are now working at integrating with their Vikings, live fire tactical training, as well as getting to grips with a mode of transport called 'skijoring' - a means of quickly transporting Marines over good ground.
Captain Roger King, Charlie Company's Second-In-Command told Forces News: "[It's] all so we can be proficient soldiers when we move on to Exercise Northern Wind, which we're working alongside NATO partners and allies as part of our collective defence."
Not everyone in Norway is an Arctic veteran and for some, it is their first time on skis.
Marine Ben Rowland says they have all tried skijoring during their novices course: "You could use that if you needed to get to a position where the ground was fairly good and you had a shorter amount of time to get there and you needed to dismount to go an assault a position," he says.
"You could use that as a really quick way of transport."
"At this early stage we're probably not quite into that but clearly understanding the Norwegian defence plan and how the Royal Marines fit into that is all part of it.
"Certainly, in the next ten years as we progress through this plan, you'll see greater depth, a greater understanding as to how the Royal Marines would potentially come forward and support our NATO ally if they needed us to defend their country."
