The conclusion.The OSINT has identified, the Russians confirm, that it was not a Su-25, but a heavy strike UAV S-70 "Okhotnik" that was shot down.
Mission gone wrong
The Russians have announced the start of its serial production this year. Currently, according to them, it is undergoing testing. Apparently, the Russian command decided to shoot it down so that it would not fall into Ukrainian hands intact.
However, it still fell on Ukrainian territory, and, of course, its wreckage will be of interest. @ukrainejournal
