## 🎯 Key Points

- Russian troops have occupied a strip 2 to 4 km deep along the border of the Sumy region, failing to expand it.
- On the Velykoburlyk direction the enemy has become more active, while on the South-Slobodian direction it has exhausted its offensive potential but continues attempts to advance south.
- The SBGS detects no signs of a buildup of forces for active assaults, but points to possible sabotage activity in the Sumy and Chernihiv regions.
- There are reports of a possible replacement of Russian units on certain sections of the front by North Korean military personnel.

Viktor Trehubov, spokesperson for the Group of Joint Forces of the Armed Forces of Ukraine, commented on the operational situation in the North-Slobodian direction, which includes part of the Sumy region, during a broadcast on the TV marathon. According to him, the situation in this area remains largely stable, but Russian occupiers have managed to "mark out" a control strip along the state border, 2 to 4 kilometers deep. Trehubov emphasized that this strip is "not deep," but its presence along the border is a significant tactical inconvenience for Ukrainian defenders.

### Attempts to expand the strip have failed

As the spokesperson noted, Russian units have repeatedly tried to increase the depth of the captured border area, but they have been unable to do so. "They can't expand it, but it's bad that they've 'marked out' such a strip right along the border," Trehubov stated. Thus, according to the command's assessment, the enemy has settled for what it has achieved and has been unable to turn a local success into a more extensive advance into the territory of the Sumy region.### Increased activity on the Velykoburlyk and South-Slobodian directions

Alongside the relatively stable border area, Trehubov pointed to the dynamics on adjacent axes. On the Velykoburlyk direction, he said, Russian troops have become more active and have begun to exert additional pressure on the positions of Ukrainian defenders. On the South-Slobodian direction, the enemy, conversely, has "somewhat exhausted its offensive potential" at the end of summer, yet it continues to attempt to advance southward. The spokesperson added that there is a noticeable discrepancy between Russian statements and its actual achievements on the ground, which he characterized as a "funny 'schizophrenia.'"

### Contradictory data

The available statements from both sides and agencies contain nuances that are important to distinguish. On the one hand, Trehubov describes the enemy's increased activity and pressure on the Velykoburlyk direction and ongoing attempts to advance in the south, which may be interpreted as an increase in the intensity of combat operations. On the other hand, the State Border Guard Service (SBGS) previously reported that it has not detected signs of a buildup of forces for active assaults on Ukrainian positions, with the main concern being possible increased sabotage activity in the Sumy and Chernihiv regions. Moreover, Russian public statements about "successes" in this area, according to Trehubov's own assessment, do not correspond to the actual depth of the captured strip (2–4 km). These discrepancies — between the stated and actual dynamics, as well as between the "pressure" on certain axes and the absence of signs of a mass assault — require cautious interpretation.

### Sabotage backdrop and possible rotation of units

Beyond the front line, a sabotage backdrop persists in the Sumy region: the SBGS indicated that Russia may intensify sabotage activity in the Sumy and Chernihiv regions. It was separately reported that on certain sections of the front, likely in northern Ukraine in the Sumy region, Russian units may be replaced by North Korean military personnel. Such a rotation, according to available assessments, would allow Moscow to redirect the freed-up forces to the Lyman tactical area. This information is probabilistic and not fully confirmed.

### Assessment of the situation

In summary, the situation in the Sumy region, according to Ukrainian commanders, is characterized by a stable border strip of limited depth, localized enemy activity on certain directions, and a persistent sabotage backdrop. The key factor remains the Russian troops' inability to expand the captured area and the mismatch between their public statements and actual tactical results. Further dynamics will depend on whether the enemy can overcome its exhausted offensive potential and what forces it will deploy to the northern sections of the front.
