Sub-zero temperatures awaited troops serving with the UK Commando Force as they travelled to the far north of Norway to tackle winter training in the Arctic circle.
Soldiers from 29 Commando, Royal Artillery; 24 Commando, Royal Engineers; the Commando Logistic Regiment and other supporting units were among a 2,000-strong contingent to take on the cold weather warfare course delivered by mountain leader instructors from the Royal Marines.
The programme is designed to equip participants with the skills needed to survive as well as teaching them how to Telemark ski while carrying Bergans.
They also faced the infamous ice-breaking drills, in which individuals plunge into freezing water with kit, before gaining their composure and then climbing out.
As well as completing the course, the soldiers carried out their own special to arms training including building field defences and establishing helicopter landing sites and forward arming and refuelling points on frozen lakes.
Divers from 24 Cdo conducted multinational training and dive tasks, while the gunners of 29 Cdo fired the 105mm light gun in the field.
