Ukrainian enters the wrong trench

GoPro footage being played on a computer and recorded by a cell phone captures the moment a Ukrainian soldier entered a defensive position that was occupied by an assaulting Russian force. Before the Russian opens fire, he appears to try and get the Ukrainian to drop his rifle. The Ukrainian reacts instinctively by putting his second hand on the rifle, which prompts the Russian to kill him. The unfortunate thing about this video is the Ukrainian was likely on auto-pilot moving between positions. When he noticed the Russians, he probably thought that they were part of his own unit. What we're looking at here is a real-time example of how the fog of war impacts troops on the battlefield.
