It is not staged, they found the TEL, and blasted it, if they prepare it ahead then keep safe distance from the missiles.Oh it was for sure staged for the cameras, and pretty badly so. I expect they slapped on a c4/semtex charge and expected only a little boom but ended up needing medical treatment most likely.
But it doesn’t change the fact it’s another Ukrainian S300 down.
If they have time then just drive the TEL back home with the missiles, it represents value.
