As British Army divers approach the end of an ice-diving course in the Arctic, they faced one last and rather large challenge – recovering an M113 armoured personnel carrier from beneath a frozen lake.

The task was taken on by 27 divers from five different countries, including soldiers from the Royal Engineers, as they reached the end of the specialist course led by the Norwegian army.

Before even attempting to recover the vehicle, personnel had to figure out what they were looking for and build a dive site on the ice – all before plunging into the freezing waters.
