Reuters: China covertly trained Russian drone/EW troops for Ukraine war

The post cites Reuters reporting that China covertly trained ~200 Russian personnel in late 2025, including courses on strike drones/FPV, counter-UAV (EW guns, nets, interceptor drones), and combined-arms tactics integrating drones for mortar fire correction. This represents a notable battlefield-relevant training/doctrine transfer that could improve Russian UAV employment and counter-UAV effectiveness in Ukraine.
