They are Soviet made weapons. Soviet made does not equal Russian very big difference as you have continually failed to grasp this simple fact with your cold war understanding of conflict. In fact if you want to be more technical they are mostly Bulgarian Soviet stockpiles (you know Bulgaria the NATO ally) that were sold and transported to the "moderate" headchopper proxies and ISIS by their Gulf, Israel, Turkish and US/NATO handlers. There is also a flourishing black-market trade of old Soviet stockpiles meant for Ukrainian armed forces. under their US lead puppet government.
