Both russia and Ukraine operate the specific older SAM (BUK-M1-2) and the missile in question (9M38M1)  but I was under the impression that there were different types of warheads and that the warhead in question was only fielded by russia. This seems incorrect though, the entire system in question is still used <i>both</i> by Ukraine and Russia. So the warhead+missile identification does not rule out Ukrainian BUK, however the claim that Russia <i>do not</i> use BUK-M1-2 with 9M38M1 missiles is easily falsifiable, so it&#x27;s really a very stupid thing to try from the russian side -- recent photos of this system in  Russian duty are easy to find. These are discontinued in manufacturing, not in field use.
