Members of a Ukrainian patrol near Kharkiv take contact from an unknown size Russian patrol. During the fighting, the patrol's machine gunner takes shrapnel in the arm.

While the wound doesn't seem that bad shortly after it happens, towards the end of the video we can see that the machine gunner is bleeding pretty bad. It's unclear how many Russians were on the other end of this gunfight, but it appears that the Ukrainians were pushed back after their machine gunner was injured.
