I don't have any sources except by speculation and spitballing, but I can only assume that Ukraine has thrown it's reserves in the form of mechanized infantry due to it's inability to make any kind of maneuver in an offensive manner towards AFRF lines.
irregardless if this is relevant or not, I hope it's a good read.
information is from historylegend's video but I wouldn't take it much more than really just anecdotal evidence
afaik 430,000+ KIA/WIA casualties means that Ukraine has lost 200 brigades if each brigade had 2,000 soldiers - this is the total amount tallied up but not by unit. I wouldn't doubt that many units have outright dissolved due to casualties like MVS 'Azov' or MVS 'Donbas'.
NATO standard battalion means that Ukraine has lost 400 battalions each worth of soldiers in the course of fighting (IIRC 1,000 soldiers.).
In bigger terms, to put this in perspective, A Corps is a 40,000-80,000 sized unit. I will be taking the liberty of saying that the Ukrainian 'corps' in this case is about 80,000 by United States Army terms. I wouldn't doubt that Ukraine is currently using old Soviet formations as I have seen ORBATs and formation documenting as such.
If we tally up total losses as of 11/21/2023 it's about 5 corps. To put this further into perspective, the United States only lost 3 corps in the American Civil War which had been dissolved from losses from WIA and KIA - but of course this is fairly different due to size. 620,000 deaths in the American Civil war in TOTAL on BOTH SIDES militarily versus the quickly creeping up Ukrainian KIA rate.
Lack of reserves means that Ukraine cannot act in an elastic defense method, to be able to quickly respond in a coagulant manner to halt Russian gains in offensive maneuvers. It also means that Ukraine's own offensive maneuvers are stunted because there are no able-bodied reserves to QRF and reinforce their gains and advances.
Without reserves you are unable to cover a front well enough or act quickly incase of a breakthrough, it's one of the first signs of a collapse.
AFAIK Operation Bagration and it's offensives were a success because the entirety of the reserves covering the front had collapsed along with the army infront of it.
The Russian Armed Forces attacked Novomikhailovka, Maryinka, Nevelskoye, Pervomayskoye, Severnoye (a settlement west of Avdeevka), on the southeastern, eastern and northeastern approaches to Avdeevka, Stepnoye (not to be confused with the settlements of the same name on the Zaporizhzhya and Ugledar directions), Ocheretin and Keramik. Two of the last two listed settlements have advancement
as per War Gonzo.
Purported TikTok from a 19 year old in Avdeevka:
Последнии кадры 19-летнего ВСУшника из-под Авдеевки. Солдатик жалуется что позиции потеряны, а им скоро крышка. У самого три контузии. Молится чтобы был шанс выбраться из этого ада, но не судьба...
А поднял бы лапки и вызвал "Волгу" на частоте 149.200 остался бы жить...1
This is fairly obviously a problem with Ukraine's inability to reinforce their gains and positions and the blatant lack of reserves which had either been thrown into Artyemovsk or into the Cyounter Offyensive of 2023. Russia is able to exploit every bit of it's mechanized forces and motorized units because Ukraine cannot properly counter it with quick-response elastic defense and counter-attack. I've also been noticing a lack of ATGMs and Fire & Forget missiles on the Ukrainian side - What does this mean?
This is the 'Форум Свободная Россия' or 'Free Russian Forum'. They are all glow-ops and this had existed since the invasion has begun.
They are all glowies and faggots, despite them not being able to do anything because most of them are ingrate emigrants.
it reinforces the narrative that any opposition to Putin is simply trying to fracture the country.
It's a foolish endeavor regardless.
