yeah, the quality is absolutely insane, that's true. If it's a fake, it's one of the best I've ever seen - and while it's reasonable to have doubts seeing such footage in this quality, I think it actually is real.
What we should never forget when watching this combat footage, that every human death is a tragedy and although one might cheer for the Ukrainians to be able to prolongue this war and showing what they are capable of, human beings' bodies were unnecessarily killed. Those soldiers have mothers, fathers, children, grandfathers, friends...ripped from their earthly existence. In the matter of seconds, for nothing.
I understand the reality of war and I am obviously pro Ukraine in this conflict, but even in the anonymity of such videos we must not forget the individuals on either side. It's incredibly sad.
War is hell.
