The casualty rate is growing exponentially:

'When Ukraine was firing 10,000 shells per day, 35-45 🇺🇦soldiers were killed daily & about 250-300 were wounded. When the daily fire fell to half that, over 100 soldiers were killed per day & at least 1,000 were wounded' https://www.reuters.com/investigates/special-report/ukraine-crisis/artillery/
