Yeah something’s off, I’ve seen articles with 9,000-13,000 Russian troops killed. Not believing much here..
(Your tagline, had a 1980 2 door. Black ,dark red fabric seats, sport trim, A/C could freeze every part of you...wished many times I still had that car!)
9-13K killed is pure speculation. But given the number of vehicles detroyed plus admitted losses of senior officers its perfectly plausible to say they’ve had 9-13K casualties (killed+wounded).
