Unfortunately, it is a big point of Russian internal propaganda which demonizes it into foreign "soldiers of fortune", "mercenaries" coming to fight Russia, basically they are making it into an additional point of how Russia in this war is basically defending itself from foreign invasion. "Ukraine is being pumped up with foreign weapons and mercenaries!". Unfortunately Russians are eating it.
As a glaring example of how gullible are Russians to their propaganda - this official Russian TV story shows planes with unguided dumb bombs (FAB-250, 500lbs) with which Russia bombs Ukrainian cities, and they call it "high-precision missiles" and "point-precision weapons" with which Russia supposedly strikes only military targets (while any Russian can find, yet wouldn't, on YouTube the videos of Ukraine cities destruction by those bombs) https://www.youtube.com/watch?v=LrekdY2FgD0 , yet if you talk to a Russian in Russia they will be screaming that they only "precision-strike only military targets".
