From the link you yourself posted-
"This seems to be the aftermath/longer video of the one Ukrainian soilder shooting a Russian/Wagner soilder in the head multiple times. The others seem to have a smilelar fate.
We can't make sure if this was Ukrainians over taking a Russian position or Russian/Wagner soilders taking on a Ukrainian position and losing/giving up. So the title is okay to stay like this.
For more context here are the first two videos. NSFL -> 1st video and the 2nd video"
