This is the right take. It's hard to imagine that Ukraine has lost less than 100,000 deaths and 300-400,000 permanent disabilities based on mobilisation data alone. Russia 2-3 times this amount just on the nature of attack vs defence, though now with a better ratio as Ukraine weakens.

But really these are ballpark fugures at best. It could be half this, it could be an order of magnitude more. But it's definitely not Zelensky's 30k.
