Casualties do not mean deaths. A wounded soldier can return to combat later.
I can't find numbers or more information about this because Google has stopped returning results that match my queries.
Should try to use alternative searches. Can recommend Kagi
In the modern warfare with drones that made "killzone" to be 30-40kms from the frontline, with current russian tactics of infiltration by small groups and inability of them running medivac groups, the ratio of wounded vs dead in casualities are nowhere near to what it was in previous wars. Don't have the exact number but some estimates were 1:1 wounded:dead ratio on Russian side
