Frozen eyeballs and hypothermia: What really happens during ops in places like Greenland

A former Royal Marines cold-weather specialist has explained why Arctic warfare can be as dangerous as the enemy, and why surviving Greenland-like conditions demands different training, kit and tactics.

Greenland's growing strategic importance has renewed focus on the High North, but the video warns that in extreme cold, the environment can kill within minutes without the right protective gear, including goggles to stop eyes freezing.

The former Royal Marines mountain leader says conditions vary across the island, from more Norway-like weather in the south to harsher, glacier-heavy terrain further north, where troops face a second battle just to stay alive.
