In this situation, it made sense to wait until the exhaustion of the other side began to make itself felt.
The Kremlin, overconfident that Kyiv was concentrating on holding out in the Donbas, certainly did not expect a thrust into Kursk Region. This area is part of the responsibility of the North army group, drawn from Leningrad Military District troops. It has been tied up in heavy fighting in Kharkiv Region since May.
A reserve group, the 44th Army Corps, was supposed to be formed in Kursk Region, which in reality
did not materialize, as some men from the new unit were probably sent to Kharkiv Region to compensate for losses on that front.
At the time of the Ukrainian incursion, there were only scattered units in Kursk Region, mainly conscripts, FSB border guards and Chechen Akhmat forces. They did not have heavy weapons, and there were no plans to use these men in combat. Though some defensive fortifications had been erected, there was no one to defend the region.
The Russian command likely assumed that the US and other Western countries, fearing an escalation of the conflict, had forbade Kyiv from bringing the war to internationally recognized Russian territory, and that Ukraine would listen.
Kyiv was looking at the problems it would face in a war of attrition: an inevitable decline in the fighting spirit of the troops and the nation’s readiness to resist the aggressor, a rise in defeatist sentiments and greater criticism of the country’s political leadership. Of no small importance is, of course, the latent irritation of Western partners (whether justified or not) that their significant military aid has yet to yield the expected results on the battlefield.
This seems to be why the Ukrainian leadership decided to shake up, if not the military situation, then the military-political backdrop. The decision reflects the view that the most important factor for victory is not general superiority in resources that can be mobilized, but the ability to covertly carry out mobilization in a short time for a specific military operation.
On the eve of the raid into Kursk Region, the Ukrainian command had managed to concentrate up to 10,000 soldiers near the border secretly, under the pretext of preparing to repel a possible Russian invasion into Ukraine’s Sumy Region. As the art of war dictates, a very small circle of army officials was involved in the planning. The troops knew nothing about the objectives of the operation. To avoid leaks, Ukraine’s Western partners were kept in the dark. This is what makes the Kursk operation so different from the first advertised and subsequently failed summer offensive in 2023.
The raid into Kursk Region was well planned and flawlessly executed. Just in the first days of the operation, Ukrainian troops had penetrated 10-15 kilometers into Russian territory, encountering virtually no resistance, and occupied several dozen settlements, including Sudzha, the district capital.
This yielded the expected military-political results. The morale of the troops and the country as a whole was bolstered, and criticism of the military command died down. The Ukrainians had something to present to their wavering allies.
