"Ukraine’s Minister of Defense [Reznikov] reveals which kinds of high-precision missiles Russia fired over Ukraine most often"

From www.pravda.com.ua | STANISLAV POHORILOV – FRIDAY, 14 OCTOBER 2022.

"Ukraine’s Defense Minister Oleksii Reznikov has revealed what kinds of missiles Russia has been firing at Ukraine since the beginning of the full-scale war; he also called an estimate of the missiles the Russians still have left."

See wiki entries for the Iskander, Kalibr and Kh-101 respectively:

https://en.wikipedia.org/wiki/3M-54_Kalibr

https://missilethreat.csis.org/missile/kh-101-kh-102/

List does not include the use of an old-fashion cruise missile Kh-22 Kitchen from several months ago. Firing of a Kitchen not it seems an indication the Russian not running out of missiles as was thought to might have been the case.

ONLY 1/3 of Russian missile capability as available the Ukraine Conflict yet to have been used. Russians having a lot more bang-stuff at their disposal. [I am not including ICBM in the mix]
