Brutal helmet cam footage shows a Ukrainian soldier gunning down Russian soldiers in two different instances from only inches away. In the first clip the Ukrainian rounds a corner and is surprised by a Russian soldier, but he is ready to fight and lets out a deadly burst, ending the Russian. Later, he is standing in a bunker when a grenade is tossed into his position. Instead of diving for cover or retreating, the Ukrainian charges forward and neutralizes the Russian that just threw the grenade. Speed, surprise, and violence of action are the key elements of victory in battle, and all three were demonstrated here.
