As reported by Censor.NET, another example of that is a new investigation of the bloggers into modern Russian drones 'Granat-1′ and 'Granat-2′ used in Donbas. They were disclosed by a Russian propagandist in a video. The footage contains scenes where Russian servicemen use the drones during military actions near Debaltseve in February 2015.
"'Miners' bought a drone in a 'military store' (or even better - captured a Ukrainian one) and learned how to pilot it professionally by reading manuals," the author of the investigation comments.
