UK Royal Marines from 45 Commando and specialist units from around 3 Commando Brigade are set to begin their 2021 winter deployment.
The intensive Arctic training is being conducted after all deployed warriors went through a strict quarantine period.
The training aligns with the Covid-19 guidelines of host nation Norway.
According to the UK Royal Navy, the Norwegians cancelled exercises with Norway, the US, the Netherlands and Germany due to the increasing coronavirus cases.
However, crucial training has been resumed for those who underwent quarantine.
45 Commando commanding officer lieutenant colonel Innes Catton said: “45 Commando is currently deployed in Norway conducting essential training as the Lead Commando Unit.
“As Cold Weather Warfare specialists held at very high readiness, this training is vital to retaining capability to deploy anywhere in the world in the event of crisis and to support our Nato allies in the region.
“Stringent control measures and quarantine procedures are in place to protect the local population and our people in Norway, as well as our families upon return to the UK.”
The ‘Cold Weather Warfare Course’ comprises of three phases, namely survival, mobility and warfare.
Initially, new participants to the Arctic environment will be put through a series of intensive trials to make sure they develop their surviving capability.
These trials include building shelters and living away from the land and dealing with cold shock during the ice breaking drills and more.
In May last year, the Royal Navy joined US forces to practise training in the icy waters of the Arctic to ensure that the armed forces are prepared for future global threats.
