It has been interesting how Russia is trying to find additional personnel (Syrians, Libyans, Chechens, Wagner group, pulling troops from Armenia, etc).
I find it quite plausible Russia has sustained heavy losses. According to the Russian tabloid Komsomolskaya Pravda, 26,000 killed or wounded.
That 1/4 of Vlad’s forced pep rally.
I saw a report somewhere that the border with Finland had also been drawn down.
