Thats not how most of the manpower gets there, without even knowing the Ukraine example, I venture to guess based on the superior morale of Ukrainian forces, that most are drafted willingly.

This still does not prove the very general statement GP made, which doesn't align with draft reality in historical wars

Many of those who were drafted willingly, already died, it’s the 5th year of war

We are talking 150k dead and 800k volunteers, and another 1 million more drafted. I don't think your statement is correct
