Your source even sounds inauthentic, the description doesn’t ring true and they cover up the captions.
The old video is probably describing the actual combat of this unit mentioned, including the casualties.
“”1st Battalion International Legion, Bravo Company in the Kharkiv counteroffensive last Sep-Oct. The team fighting was the most experienced in the battalion. It WAS a Spetnaz stronghold they took. They lost 2 to artillery & 1 to a sniper, several WIA.””
So it’s straight from the Ukrainian military or not trustworthy, in your opinion? None of the reporting from all those 3rd parties not involved in the conflict, ONLY the Ukrainian talking points allowed. How ridiculous.
