While the capability of the Kinzhal is no doubt overstated by Russia and potentially by military pundits going off Russian claims plus rumours, it should be
heavily noted that the patriot battery that shot down the incoming missile was also the target of the missile.
To put this in perspective, during WW2 a German Tiger 1 tank managed to successfully shoot down an IL-2 Sturmovik ground attack aircraft that was descending towards it for the kill. While that shot still required serous accuracy, lead, etc by the gunner (to be clear it used the main cannon not the twin machine guns) it was made infinitely easier by the fact the target was coming straight at it while descending, had it been any other angle the shot would have been impossible.
This isn't to hate on the patriot, hell they've downed more RAF jets than Russia ever has lol, but if people are expecting this to become the norm they may well end up seriously disappointed (I hope not, but I'm being realistic rather than optimistic in the outlook). Russia have now confirmed that the patriot can indeed shoot a really fast fish in a barrel when pointed at the barrel and will probably not attempt that again (assuming ofc the first time was actually intended to kill the patriot and not just test it's capabilities).
More combat effective than
what's left of the Russian army.
Let's not forget they lost like 300+ Spetsnaz on the first day and things didn't improve that much after then, the quality of the Russian Army has decreased almost as much as the quality of their equipment has
