They're in the Arctic as part of the Commando Helicopter Force's annual winter training serial.

Yeovil's Commando Helicopter Force is running the exercise in Northern Norway.

For the pilots landing in the snow is not dissimilar to landing in the desert they still get that goldfish bowl effect but instead of dust its snow.
