Russian soldiers have been put through their paces performing physical and mentally tough military drills inside the Arctic Circle at freezing temperatures.
The Russian Marines were battling minus 30 degrees Celsius as their white uniforms blended with the snow in leaked video footage filmed near the city of Murmansk in north-western Russia.
It has been released by the country's Ministry of Defence to show the West just how tough Valdimir Putin's marines really are.
The elite soldiers are seen undergoing weapons training with AK-74 assault rifles, grenade launchers and explosives in deep snow.
A Russian Ministry of Defence spokesman said the marines trained in very harsh weather to ensure they were prepared for combat in all conditions.
