Russia Ukraine war, page-184996

I've done a bit of thinking about troop replenishment too .
For Ukraine 18 yrs back there were over 400,000 live births ....assuming reasonable survival there should be 200,000 Ukrainians males now turning 18 this year .
If you can enlist half of those (drafted) then that is a reasonable top up of troop numbers ....and presumably something similar happened last year as this war has already been going 20 months .

We don't know what Ukrainian losses are although reasonably high ....we don't know how many casualties are permanantly unfit either.
Women fighting , women in auxilary duties - stores , drivers , comm's etc unknown .
We do know Ukraine are being much more careful not to "waste lives".

russia has much greater capacity to mobilise but less willingness - politically difficult .

One more thing to keep in mind is assuming sufficient equipment , it needs less men and is easier to defend tha to attack .
We saw russia taking 10 months to fully take Bakhmut ad now the counteroffensive by Ukraine painfully slow - very hard to brreak defences .
For this reason even an advantage gained by either side in equipment supply won't bring a quick end to this war .

all in a ll .....and I could be wrong ..... I don't think troop numbers will decide this war ....but equipment supply OR russian economic/political collapse
