@Render this jives with what's been reported on the Russian military over the past ~15 years: they have a small core of professional soldiers, augmented by mercenaries, and most of their numbers are young, green conscripts mainly suited for garrison duty. During the run-up to the invasion, all this talk of "180k+ troops ready to invade" didn't sound right to me; I didn't think there were 180k veteran, well-equipped troops that were going to advance into Ukraine.
@Render I remain skeptical - the information battlefield is well-prepared by both sides with propaganda that casts the opponent as weak - but there is mounting evidence (like this thread) that many of those numbers are boys barely old enough to shave that were thrust into a war they didn't know they were going to fight, not even boys who had been in uniform for a year and used to the rhythms of military life.
