I personally observed what remains of "a tank that has no analogues, and a tank that the West will not be able to create soon!" after hitting them Javelin/NLOW
I personally saw what a tank that came under fire from an RPG of the previous generation looks like. If there was no hit in critical areas, the tank lives long enough, and it will have marks from the hit, but it will be more or less intact. Yes, I saw how the process of tank death looks like, when the shaped charge burns through the armor, and the tank ammunition explodes. Pillars of fire, from all openings, primarily through the hatches and gun barrel. But to achieve this was quite difficult. And in the conditions of "battle in the field" it is extremely difficult.

But a tank that, after the first hit, turns into a mega firework, and launches its tower up to 20 meters - I have never seen this! Even if you weld a "unparalleled" lattice on the tower

Yes, and most importantly. The Russian army is a projection of the USSR army. At the same time, almost nothing has changed in it. The same stupid generals, the same orders "by this date, take this object at any cost" and ... YES, tank columns, as the main means of gaining superiority. It worked, in the days of primitive means of combating armored vehicles and tanks specifically. But after the advent of Javelins / NLOWs and the like, Russian tanks became mobile crematorium graves for their tankers.
