Why are the photos taken at a distance
Because the camera that captured them was at a distance.
Just a guess, maybe Ukranians didn't want to go somewhere, or send their drone somewhere that could easily be blown up. They don't train them like they do in Russia.
and why are no bodies visible?
Probably some in the tanks that still have their lids on. And the guys that were in the tanks that got blown open are no longer a single piece of human anymore.
