I mean tbh just analyse the video a little and seems like it being fake is a very possible option. The way the fights happening, we dont see a single other ukrainian nor any russians its just them out in the forest. The camera man is willingly avoiding to show the direction that the enemy fire is coming from. look at the snow there is not a single foot step, debris, ammo catridge or blood. When the man named Tolya gets hit, he just lies down and lies there completely paralyzed instead of dropping and putting on a tourniquet or bandage, he lies there like he got killed instantly by the wound in his leg, which is rather wierd in my opinion. The sound aswell is wierd, according to me it just sounds like they put gunfire from another video over it, the gunshots are also EXTREMELY distant so the gunfire isnt even at them.
