Russia’s military command is trying to frame 2026 as a year of renewed progress. According to the chief of the Russian General Staff, Russian forces have taken control of 80 settlements and more than 1,700 square kilometers of territory since January, while advancing toward what Moscow calls the Donbas “fortress belt” of Sloviansk, Kramatorsk and Kostiantynivka. Ukraine has not confirmed those numbers, and independent pro-Ukrainian mapping projects suggest a far smaller Russian advance, closer to roughly 600 square kilometers. That gap is the heart of the story: Moscow is fighting not only for land, but for the perception of battlefield tempo.
What matters most in the Russian claim is not the number itself, but the geography behind it. The Kremlin is again emphasizing movement toward the Sloviansk-Kramatorsk urban cluster, the last major defensive urban system Ukraine still holds in the government-controlled part of Donetsk region. That is why references to Russian forces nearing Sloviansk and Kramatorsk carry not only military meaning, but psychological weight. Moscow wants to show that its long war of attrition is finally bringing it closer to its central political aim in Donbas — not simply pressuring the front line, but cracking the structure of Ukraine’s eastern defense.
According to Daycom’s earlier analysis, the so-called fortress belt is not just a group of cities. It is the backbone of Ukrainian defense in the east, a framework that has slowed Russia’s push deeper into Donetsk region for years. Sloviansk, Kramatorsk and Kostiantynivka matter not only as population centers, but as logistics hubs, supply nodes, command points, political symbols and the last major barrier to Russia taking the part of Donetsk region it still has not been able to seize despite years of fighting. That is why even limited Russian progress toward these cities immediately carries significance far beyond any local tactical gain.
But this is also where the most important qualification begins. Fighting around Kostiantynivka, Sloviansk and nearby sectors does not automatically amount to a breakthrough. Ukraine’s General Staff continues to report repelled Russian attacks near Sloviansk, near Kostiantynivka, and along border areas in Kharkiv region. In other words, even if Russian pressure is intensifying, it is still meeting the high cost of assaulting prepared defenses, local Ukrainian counteractions, and the broader difficulty of turning pressure into operational collapse. This is the defining paradox of the current phase of the war: the front is moving, but not breaking at the speed one side would like to project.
That matters especially in light of signs that Russian momentum had slowed in March and April, according to some independent observers. Several open-source assessments suggested that Russia’s territorial gains this spring were not as extensive as during earlier waves of offensive action. That is why Gerasimov’s statement can be read not only as a military report, but as a form of informational compensation. When battlefield tempo does not produce an unambiguous strategic effect, it is often reinforced through the political language of steady forward movement.
It is also important to look at how Russia is broadening the frame of the war. Gerasimov is speaking not only about Donbas, but about advances in Sumy region in the north and Kharkiv region in the northeast to create what Moscow calls a “security zone.” This is a familiar Russian logic: local offensive actions near the border are presented as defensive measures, even though in practice they stretch Ukrainian resources, force Kyiv to hold reserves across a wider front, and complicate the defense of the main operational directions. In that sense, the issue is not just how many kilometers have changed hands, but how effectively Russia can force Ukraine into a wider perimeter of exhaustion.
It is equally telling that both sides are increasingly fighting with numbers as well as weapons. Russia cites 1,700 square kilometers. Ukraine’s top commander previously said Ukrainian forces regained nearly 50 square kilometers in March alone. Independent maps offer yet another picture. This does not mean the truth is unreachable. It means that in modern war, truth becomes layered: operational reality, political messaging, propaganda and cartographic interpretation do not always converge in one day or in one statistic.
In the end, the significance of the Russian General Staff’s statement lies not in proving that a major breakthrough has already occurred, but in showing where Moscow sees its main opportunity in 2026. That opportunity lies in Donbas, in the fortress cities, in pressure on Ukrainian logistics, and in convincing everyone — from the Russian public to Western capitals — that Russia is moving forward slowly but inevitably. But this war has already taught a harder lesson: square kilometers matter only when tactical movement can be converted into strategic rupture. And that is precisely what Moscow, despite years of combat and increasingly ambitious numbers, still has not demonstrated.
