I can't speak to the presence of Wagner and exactly who they may have been replaced by, although we are tracking all of those kinds of questions.
I would fully expect that Wagner would remain in Ukraine. They are a very important part of the Russian illegal operations in that country. This is despite the fact that Wagner has taken incredibly heavy losses. One estimate suggests that of the 50,000 troops it has deployed, it has lost 30,000. I can't verify those numbers, but they are really testament to the fact that Wagner is willing to be present in the most dangerous and active fighting zones of Ukraine. Of course, their motive is not ideological. It is profit-based. They are being paid for their activities in that country, which are substantial.
