As i said Russians have been using turbo prop drones in Syria for long time. so i am sure they know incremental value of drones that are better as it is Russian that training Irakis on Mi-28 choppers who also use drones.What integration and training?
6 months before the war you "buy" two squadrons of WL-2 - I'm sure China would have loaned them for free. In the war they are operated by Chinese civilian operators, like Turks are operating Ukrainian TB-2s. Except as Ukrainian AD is largely suppressed they would be operating with impunity.
China gets real world experience of drone warfare, Russia gets free kills, even Ukrainian nazis get to go Valhalla. Everyone wins.
Russians are either too proud to use Chinese platforms or too dumb to recognise the importance of drones in modern warfare. Your own equivalent the Orion is not being deployed in numbers needed to make a difference.
absence of videos does not mean they are not using Orion drones extensively. when there is so much Nato radars. i dont think a turbo prop drone is surprize factor.
