The surprise wasn't Russian defences collapsing. Even since the arrival of GMLRS and the procession of strikes on the Russian depots, I was expecting a collapse at some point. The surprise is how it was inflicted. The expectation was that the Ukrainians would slowly chip away at the foundations until the whole edifice collapsed, and that is largely what they are trying in Kherson. In Kharkiv, they just assembled the biggest wrecking ball they could and launched it at the Russian positions.TopBadger wrote: ↑Thu Sep 08, 2022 9:10 amWhilst underestimation of an adversary is dangerous - I think it's the case that Russian capabilities have been consistently overestimated during this conflict.EACLucifer wrote: ↑Thu Sep 08, 2022 4:03 amMost of us were expecting accelerated attrition, not armoured fists and rapid manoeuvre.
Perhaps we should be less surprised if their defenses collapse like a flan in a cupboard.
Lets all remember that, supplies aside, the Russians simply aren't motivated to be flighting in Ukraine and appear to lack the professionalism to even look out for each other.
We've gone from analysts wondering if massed armour formations like the one observed in this tweet are even possible in the modern era to watching them smash through the Russian lines.
It shows that the Ukrainians have exceptionally good air defence in Kharkiv, and also that the Russian Ar Force lacks weapons to attack tank formations at standoff range - they have no Brimstone equivalent.
And analysts were also talking about the near impossibility of achieving operational surprise, and then this happened.
The Ukrainian breakthrough has seen them overrun Russian positions, capturing ammunition depots, significant quantities of towed artillery and even self-propelled guns. Russians units were ambushed and destroyed, apparently while retreating. Some Russian units abandoned their vehicles to be captured.
The Ukrainian attacks appear to be bypassing settlements and allowing following echelons to capture them - which was Soviet doctrine since some time around Stalin's purge - and this enables them to outpace the Russian defences. Balakliya, for example, appears to have been encircled a couple of days ago and liberated today. The Russian army is slow moving, and is faced with the issue of exterior lines vs interior for Ukraine. For example it took them a couple of weeks to redeploy to Kherson oblast to face the very heavily telegraphed Ukrainian offensive there, and that was when the bridges were intact. The speed of the Ukrainian advance is outpacing Russia's ability to reinforce their front, for the moment, and the areas attacked appear to have been largely garrisoned by a mix of Rosguardia riot police and forced conscripts from the occupied territories. That situation won't last forever, but if it can be exploited while it does last, it gives Ukraine a real advantage.
I've seen geolocated footage of Ukrainians putting a flag on a radio mast within touching distance of the Oskil. While the full extent of the Ukrainian advance is not clear, it does appear to be threatening the supply lines to Russia's Izium grouping. Ukraine's figures for the distance they've advanced (50km) and pro-Russian channels assessment of Ukrainian troops' distance from Kupiansk (about 10km) agree with each other. The liberation of Kupiansk would be a stunning victory, but even if it does not prove possible to liberate the city, getting near to it, and perhaps making contact with the Oskil further south, cuts the principle line of supply to the Izium grouping. With Ukrainian forces crossing the Siverskiy Donets near Lyman, the effective encirclement of Russia's Izium grouping is threatened.
Whether or not they are able to continue this advance - it will culminate sooner or later and it is vital the Ukrainian commanders recognise when this happens - the armed forces of Ukraine has in a few days liberated more territory than Russia took in the preceeding month, and it appears to be the single biggest advance by either side since the Russian collapse in the north back in spring.
