Weirdest part of this (y'know, other than the presence of Russian terrorists in Ukraine) is the birds chirping. Two bangs from an extremely loud rifle, and they just carry on like nothing happened.
...or is the audio replaced for opsec or something?
Possibly. The shooter is pretty far from the targets. Looks like at least a full second of flight time before impact. Most big bore rifles are at least 2400 feet per second, so the target is 800+ yards away. That's a hell of a difficult shot, and the way the cross hair is directly on the target leads me to believe this is a computerized scope which is compensating for bullet-drop and windage.
