The third video shows a missile attack on the building of the Kharkiv city administration, where at that moment a gathering of nationalists was taking place.
Was the meeting taking place in those cars driving in front of the building? Because that's where the missile hit. And what happened to the "bases and firing positions"?
Speaking of which, apparently Ukrainians have a "base" and/or "firing position" in every fucking building in Mariupol, Russians bombed all of them, and still can't take the city. Is there perhaps a bit of a problem with this "bases and firing positions" nonsense?
The strategy of the 'defenders' did indeed seem to be to use multiple civilian buildings and keep the civilians hostage in them while doing so. At least that's my analysis based on the footage I've seen and the pretty much universal testimony of the liberated civilians. You know, the 'millions' which Russia for some reason 'kidnapped' thus accounting for why they ended up behind the lines of Russian protection. I've heard a few say that the Russian did try to avoid shelling the lower floors out of deference to the human shields held there, and some visual evidence seems to substantiate this.
I cannot help but be somewhat impressed at how the Russians are prosecuting this 'special military action' so far based on what I can see and verify. It's what I would do if I where aiming for the outcome that I suspect the Russians actually want, but I am surprised that the execution is as good as it seems to be. It's pretty hard to control military units, and especially in the 'staged but real' atrocities against Russian POW's and over-the-top Western media propaganda. People who think that this make me a 'Putin Fanboy' or whatever are welcome to do so because they are such ignorant bottom-feeders that it means zero what they think.
