This one seems like it could be verified. Where is the journalist's article who posted these?
No idea. All I know is that some Western journalists took pictures of it.
I don't know if they have already written this article or not.
I saw this serial number in Russian telegram channels...
If I were a general with absolutely NO conscience at all and I got ahold of serialized weapons, you can bet your ass I'd do the most terroristic things with it if it gave me some sort of advantage (which putting fear in people does have as far as war is concerned) because it would be easy to place blame on the other side simply by saying "See look, serials match those of the opponent, it wasnt us!".
This is also one more argument:
2. Tochka-U hit from the side of the Ukrainian troops. This can be judged by the location of the debris.
Although I have no idea how to check the serial number or flight direction. This can probably be easily verified if you have some experience.
I would also say that such provocations are not good for Russia, since Russia is very weak in the information war.

I think the result would not be instilling fear, but embittering the enemy.
The media regularly reports on the brutal killings of civilians by the Ukrainian military, this only leads to a desire to quickly rid the world of this threat of Ukrainian Nazism.
