Translated from source:
Shooting and liquidation of underground mines in Andriivka.
The episode from the ambush on the occupiers. When the enemy tried to change position, the Russians came into the field of view of our UAV and shooters.
The occupiers proved that they were “Russian” and turned into 200 by the efforts of attack aircraft from the “MYRON” platoon. The work of the 2nd company of the 2nd assault battalion.
Because I thought it was catchy I looked into it. The song is Я РУССКИЙ (I am Russian) by Shaman, who is a solid Putin supporter and seems to be very pro war.
I think this is the equivalent of an enemy of the US posting a video of US soldiers getting killed with “proud to be an American” playing over it.
That’s my take anyway, someone from Ukraine could probably give a much better idea of the context.
that’s the reason why I find it quite interesting
