I wonder what was the situation here. Looks like they placed two explosives on the camera-unit and took their sweet time to take that down. Isn't there operators around with shotguns to drop drones or any other kind of personnel on site? Additionally that Murom-M seems to be commercial system meant for building and area surveillance, not military use. That of course doesn't mean much, it can still be quite useful hardware.
Still, that scene with a bit better camera and action music could be a part of a movie, not something I'd expect from a war zone.
