Aren't the Russians and Ukrainians both using 7.62x39 or are the Russians using 5.45x39? Regardless of what caliber is used how would they be able to tell who is hit with what?
My understanding is that the Russian forces in Ukraine are using the 5.45x39.
Ukrainians are probably using whatever they can get their hands on.
