The AFU was operating with 800k active personnel last year plus the 500k they just mobilized. They got 2.7million in reserve according to wiki.
Azov got manhandled in Mariupol and according to wiki they got around 2.5k. Im extremely skeptical over your claim of 10-20% fam
Do you really think you can compare pre-mobilized Azov membership before the war, with post-mobilized AFU total forces during the war? It stands to reason the number of active Azov members scaled proportionally, and they've also been folding in the neo-Nazis recruited from overseas as mercenary forces, enough that whistleblowers spoke out about the war crimes their fellow mercs were committing. And again, that's just counting the formal Azov forces who are avowed neo-Nazis, we simply have no way to reliably estimate amount of Banderite / Nazi true believers and affiliates throughout the rest of the AFU. All I can do is sift through social media and war reports provided by both sides of the conflict. And in that vein, Nazis are definitely heavily represented among footage provided by the UA forces themselves, but that also begs the question of whether they're overrepresented- Azov types are so keen on spreading videos of themselves killing people on social media, while conscripts taken from rural farms in the UA hinterlands probably have a lot less access to english-language social media.
There's no way its less than the proportional 2% figure if you divided total AFU by Azov pre-mobilization. You see way more than 1 in 50 ukrainians with SS tattoos, black suns, etc. If you can't throw a stick in the air without it landing on a Nazi, they aren't a 0.001% of the forces
