Yesterday Donald Tusk, PM of Poland in a speech he claimed AFU suffers 27K losses per month.

I watched it from another source, but I believe it was the same video. There were no English subs, but audio translation which had some skips. Did not find the part when he says 27K.

Not many other source reports hits, chiefly Russian, and I think no western at all.
Here's Budanov saying they need 30K to keep on.
