"according to an article by Russian news outlet voennoedelo."

I thought it was 1.7M reported.

That's obvious nonsense. Just to remind, during WWII Soviet Union suffered 7.9M killed and missing in action (same metric). Out of prewar population of 190M. Ukraine had a prewar population of under 40M even including the already occupied territories and at most 35M without. 1.7M killed and missing will mean higher loss rate than Soviet Union during WWII and it was thoroughly depopulated.

Ukraine is barely scratching the surface of its manpower reserves - i mean, i have lots of lots of acquaintances or friends there. Some got drafted and are fighting, a few volunteered, most have some way to avoid service which they of course exploit to the fullest, one is in hiding to ditch an already issued draft notice, but no one got killed or maimed yet. One guy suffers from PTSD but he got it 10 years ago fighting for Donetsk, not during the full-scale invasion.

Most importantly, under-25 are not even conscripted yet. And they make the bulk of truly capable fighters.
