I guess I am failing the translation test. Papua New Guinea, IIRC, is a different state than Turkey, and the S400 missile system is Russia's homegrown product, not some NATO surplus.
I would be pretty shocked that Turkish armed forces were shooting at Russian, if the reports of Russian arms sales to Turkey are true.
Russians like to sell very old and bad weapons of NATO. Sell S-400 to savage tribes of NATO, for example Turkey.
