Haunting footage of Ukrainian soldier stalking and killing Russians in snow-covered forest no-mans-land is revealed in new BBC documentary

Haunting footage revealed in a new BBC documentary shows the moment a Ukrainian solider stalks and kills two Russians in a forest buried in snow.

Jamie Roberts' extraordinary BBC Two doc, 'Ukraine, Enemy in the Woods', paints a chilling picture of the true frontline with heartstopping clips showing fighting in the frozen expanses of Kupyansk woodland.

In one shocking piece of bodycam footage captured by a brave Ukrainian soldier, he and a group of fellow fighters can be seen ducking behind tree trunks, as they scour the icy landscape.

'Someone's shouting, but I can't see anything. I'll keep on watching. Do you copy?' he says.

Viewers follow his gaze as he looks around the barren forest, before lifting his gun into the frame in an apparent act of preparation for an attack.

Like a scene from a warfare videogame, the soldier begins to pace down a pathway, already littered in footprints from other unseen soldiers.

He crouches behind a pile of snow-covered logs and branches, seemingly trying to camouflage himself into his surroundings as he warns his teammates: 'The enemy had infiltrated the area'.

Tensions rise as the soldiers continue their hunt for the enemy, with the soldier filming occasionally peering over the fallen branch to give viewers a glimpse of his view.

But with such thick layers of snow in the way, nothing can be seen.

The soldier bravely reaches up on to the log to swipe away a thick clump of snow that was blocking his vision - a move that may have been deadly had there been Russian enemies watching the area.

As he turns his head, the bodies of Russian soldiers can be seen bleeding out into the fresh white snow.

'We could see there'd been a huge gunfight,' the solider says.

'Dead Russians were everywhere'.

As he and the group hide out near a deep ditch, guns in hand, the soldier can be heard shouting 'Who's there?' in a heart-stopping moment.

As tense minutes pass, viewers are left on the edge of their seats in the anticipation of an enemy jumping put from behind a tree or out from within the deep snow.

Then suddenly the soldier makes an urgent warning.

'Vovan. There's a f***** near your position, 50 to 70 metres away'.

His camera focuses back down onto his gun, wrapped in green tape to a flashlight, as he prepares it for use.

'He's just sitting there, doing nothing,' he says.

The footage snaps back around to a dead body lurking behind the solider, giving a chilling indication of what's to come.

The solider stands up and slowly creeps ahead through the snow, but no enemy presence appears to be in sight.

Then out of nowhere, the soldier raises his gun and begins firing into the distance where for a split second a head can be seen peering out from above a log.

After gunning the area repeatedly, the soldier comes to a standstill and assesses the situation before firing again.

A Russian can be seen struggling to stand from behind a fallen tree, shaking as he attempts to grip onto the trunk and return fire.

But he is too slow.

The Ukrainian soldier can be seen making his way over to where the Russian was hiding, gun still poised and ready for a counter-attack.

He edges closer to the body as it comes clearly into frame, and it can is shown lying on the snow in a pool of blood.

In an effort to ensure the safety of himself and his team, the soldier fires another few rounds onto the body before darting away, saying 'watch out, it can explode'.

The Ukrainian soldier is alerted to another Russian moving behind him, but he quickly takes him out too before the footage is cut to blackness.

A hair-raising message appears on the screen.

'Guru, it's Vovan. I finished them. Do you copy?' 

The 59 minute BBC documentary was aired today and is available on BBC iPlayer.

It explores the real-time story of a single Ukrainian infantry company who find themselves in a life or death battle to defend the eastern front against a spate of intense Russian attacks.

Filmed by Ukrainian soldiers, viewers are given an insight into one of Ukraine's most violent battlefronts and the soldiers carry out a mission to defend a railway line.

Last month, Ukrainian President Volodymyr Zelensky said around 31,000 Ukrainian soldiers have been killed during Russia's full-scale invasion. 

It comes after Russian forces were hit by one of the single most devastating blows of the war last month when a Ukrainian HIMARS missile strike wiped out 65 soldiers ordered to line up in formation by a blundering commander.
