WaitUnfortunately this is not outright nonsense, and the Russians themselves have admitted and even boasted about the S-300 strikes on target land.
The missiles used for ground operation are those with expired shelf life to be disposed of, produced in the 80-90s. There is no point for Russia to bother with costly lifetime extensions when it has an established assembly line production facility.
They have about 5000 old C300 missiles that they use for ground strikes, no accuracy, but for a nightmare of civilians it will do.
It has a range of about 180 km after a slight modification. The accuracy is plus or minus 500m, because at such a distance it is launched as a rocket launcher. But it hits the cities. And it has been done for several months, in summer they started to use such way in Nikolaev. The Ukrainian army has not so many missiles left... This is just a lot of this stuff with expired shelf life.
So you are implying that Russia used an old S-300 missile that was repurposed as a small TBM when it has thousands of Cruise Missiles?
