"The Patriot missile is proven to defeat Scud missiles in real combat" - no it isn't. It quite notoriously mostly failed to intercept Scud missiles in real combat. It has been heavily upgraded since and modern Patriot batteries would likely succeed at intercepting Scud missiles, but this hasn't been proven in real combat.
This was IIRC an issue back in 1990s due to how the system calculated time. So operation of a system continuously for more than 20 hours would cause the system to become ineffective until it was rebooted.
Thanks in major part to Israel, modern patriot systems have been rigorously tested via fire. To equate the current systems to the ones from 30 years ago is very disingenuous.
Patriot missile batteries in Ukraine have so far successfully intercepted all Khinzal Hyper-sonic Missiles launched by Russia. (At least, the ones that entered their Area of Operation)
The comment I replied to specifically said "The Patriot missile is proven to defeat Scud missiles in real combat". That is a false claim, as I asserted, and none of what you mention says anything about defeating Scud missiles in real combat.
