seriously first they buy russian quipment to copy the technology and then they dont want to be listed as operator dumb motherfuckers.

Typical american bias here in wikipedia, americans are bunch of scumbags. Hey look at us we buy russian equipment so we can steal technology but we still gonna say russian army is shit and dont wanna list as part of our army. Americans are all a bunch of hypocrites
