This was an intentional leak. Preparing Russians for the bad news they will be getting soon.
The fields of Ukraine run red with Russian blood. Or Chechen and Buryat blood at least. Just today there is a report of a Septsnaz brigade commander KIA in Mariupol.
This 48 hour operation has gone totally FUBAR for the Putinist invaders. They’ll of course claim victory but Russia has been exposed as a hollow and fake nation to all but true believing Putinists.
