October 21, 2025 (NEO - Brian Berletic) - Russian forces in recent weeks have been increasingly encircling the cities of Pokrovsk in central Donetsk while approaching Lyman and Siversk further to the north. Looking at various live mapping projects tracking the ongoing conflict in Ukraine, nascent pincers appear to be emerging in what some analysts believe could be a large-scale encirclement of what remains of Ukraine’s “fortress belt” in the Donbass region.
Comprising a number of heavily-defended built-up urban centers from Kostiantynovka and extending northward toward Kramatorsk and Slovyansk closer to Lyman, Ukraine’s remaining fortress belt likely comprises thousands, perhaps tens of thousands of Ukrainian forces. Their encirclement by Russian forces would deal a catastrophic defeat to Ukraine and its US sponsors and signify the achievement of a major Russian objective amid its ongoing Special Military Operation (SMO) - the full capture of the Donbass region.
Over the next weeks and months, the fate of this military operation will be decided, both on the battlefield in the Donbass region, far beyond it in the strategic depths of both Ukraine and Russia, as well as geopolitically worldwide.
Realities of a Major Donbass “Encirclement”
While many may imagine a World War 2-style physical encirclement of Ukraine’s fortress belt by rolling columns of Russian armored and infantry units, the encirclement will much more likely take the form of an operational, rather than physical envelopment.
Russian ground forces will continue their incremental advance along the line of contact, approaching Ukrainian-held towns and cities, besieging them, and eventually taking them, ensuring salients that emerge are well-protected from Ukrainian-counter attack as well as from the sort of operational envelopment Russia itself has been and seeks to continue to impose on Ukrainian forces.
Instead, Russian long-range warfare capabilities and drone warfare in particular - which has evolved rapidly in terms of both quality and quantity - will be able to target Ukraine’s line of communications along the entire rear of its remaining fortress belt. With the inevitable fall of Pokrovsk to Russian forces in central Donetsk and Russian forces approaching Lyman in the north, Russian FPV (first-person view) and fiber optic drones will be in range of virtually everything in between.
The encirclement of Pokrovsk and the emerging salient extending north reaching almost directly west of Kostiantynovka has already compromised logistics for Kostiantynovka itself. As Russian forces consolidate control in this region, drone operations targeting logistics for Kramatorsk and Slavyansk will become increasingly effective together with Russian forces doing likewise while moving from north to south near Lyman and Siversk.
The closer these pincers get to one another, the more effective operational encirclement will become and the more precarious Ukrainian positions will become in between them.
Just as Pokrovsk itself does not require complete physical encirclement by Russian forces to severely compromise Ukrainian logistics and thus undermine defensive positions inside the city, Russia does not necessarily need to physically encircle the Kramatorsk-Slavyansk section of Ukraine’s fortress belt to severely compromise both logistics for it and military positions within it.
In some ways, an operational encirclement would be preferable to a physical envelopment.
Because Russia is fighting what is essentially a war of attrition seeking to demilitarize Ukraine rather than focusing on the rapid seizure of territory, it seeks to force Ukraine to commit huge amounts of reserves to Pokrovsk and elsewhere along the fortress belt to meet well-established Russian military positions and long-range fires.
A rapid Russian advance toward the Dnieper River or beyond, would be costly and would afford what remains of Ukraine’s forces the ability to operate closer and closer to their own base of material support along its border with NATO. Instead, Ukraine is forced to continuously send troops and material to the current line of contact where Russia is destroying it.
Western Actions On and Beyond the Battlefield
The Western media now accepts that Russia is both fighting and decisively winning this war of attrition and that there is little the US and its European client states can do to stop it - at least in terms of continued military support for Ukrainian forces.
