Thank you Skybird-Though you forgot to quote two sentence
"I'm only interested in the Hit percentage."
"Russia fired 75 missiles against Ukraine yesterday-The Ukrainian air defence shot down 30-something."
Would the hit rate have been higher if they had Iris-T ?
Maybe, Maybe not.
I tried to find info about it on the web-Only thing I found of interest was this wiki page
https://en.wikipedia.org/wiki/IRIS-T
