Briefly
A localized operation to clear the city of occupying units is underway in Kupiansk, Kharkiv Oblast. According to Viktor Trehubov, head of the communications department of the Joint Forces Group, most of the enemy is concentrated in the city center — in a single block of apartment buildings. This gives Ukrainian units the opportunity to complete the clearance in a targeted way and minimize risks.
"Most of the enemy is concentrated in the city center in a single block of apartment buildings. So the aim now is to finish clearing that block directly and, preferably, without casualties among Ukrainian servicemen."

What is happening and why it matters
The command reports that Russian attempts to restore positions and establish a land connection to the city have so far been unsuccessful. The concentration of the enemy in one block indicates problems with logistics, limited reserves, and difficulties in maneuvering. According to the command, as of 22 December 2025 there were about 100 occupiers in Kupiansk.
This is not only a local tactical detail. If the enemy cannot build up forces or restore a supply corridor, its ability to maintain control over the border strip weakens — which increases Ukraine’s strategic space along the border.
Tactics and consequences on the ground
The urban concentration of the enemy produces two key effects: first, it allows for targeted clearance with fewer losses; second, it makes it harder for the occupiers to covertly bring in reinforcements. At the same time, risks to civilians and the need for precision remain high — which is why the operation is being conducted gradually and based on intelligence.
The spokesperson also noted that pressure to the east of Kupiansk has not produced the desired result for the occupiers, and their plan to create a "control zone" along the border in Sumy and Kharkiv oblasts remains declarative.
Context and corroborating evidence
Russian leadership has repeatedly claimed supposed full successes in the region, but the facts on the ground are different: in December 2025 the president visited Kupiansk — a signal that the enemy does not control the city. Analysts point out that the appearance of a large number of troops concentrated in a compact urban block more often indicates a defensive and forced position, rather than an ability to push forward.
Conclusion
The concentration of occupiers in one block is an opportunity for systematic work by the Ukrainian Armed Forces: a localized clearance reduces risks and undermines the Kremlin's attempts to create land corridors. However, success depends on continued pressure on the enemy's logistics, quality intelligence, and partner support. Whether Moscow can redeploy forces and change the situation is a matter of time and resources — and it is now up to us to proactively turn tactical successes into lasting border security.
