The armed forces of Ucrânia consolidated one of the most effective maneuvers in recent months by recovering a territorial extension of more than 200 square kilometers in an interval of just four days. The operation, carried out in the second half of February, marks the most significant advance by Kiev troops since mid-2023, surpassing in volume and speed the achievements recorded throughout the month of December of the previous year.
Intelligence reports and field analyzes indicate that the success of the attack is directly linked to the momentary collapse of the opposing units’ communication systems. The Russian logistical disarticulation allowed the Ukrainian battalions to advance quickly, exploiting gaps in the enemy defense line that was temporarily “blind” and without centralized coordination.
The Instituto of Estudos of the Guerra (ISW), based in the The effectiveness of the action surprised international observers, as it reversed trends of stagnation that had characterized the front since the summer of 2025, demonstrating a new capacity for tactical adaptation on the part of the Ukrainian command.
Impact of technological blockade on operations
Military experts point out that the determining factor for the change in the scenario was the interruption of Russian troops’ access to the Starlink satellite network. The technology, which had been used irregularly by Moscou forces to compensate for deficiencies in their own radio and data systems, suffered a critical blockage detected at the beginning of the month.
The loss of connectivity generated a ripple effect across Russian lines, compromising three fundamental pillars of modern warfare, as reported by military bloggers who follow the conflict on the Russian side:
• Immediate and secure communication between combat units on the front line;
• The command and control capacity to coordinate defenses and counterattacks;
• The precision and navigation of drones used for surveillance and tactical bombing.
The measure to restrict the use of the network by unauthorized terminals, announced by businessman Elon Musk, created an operational vacuum that was promptly taken advantage of by Ukrainian intelligence. Sem the ability to circumvent Kiev’s electronic interference systems using the satellite network, Russian artillery and drones lost effectiveness, opening safe corridors for the advance of Ukrainian infantry and armor.
Recovery of strategic areas in the east
The main focus of the counteroffensive was concentrated on a vital region located approximately 80 kilometers east of Zaporíjia. Esta specific area had suffered from constant Russian advances over the last year, making its recovery a point of honor and a strategic necessity for stabilizing the defense in the south of the country.
Markus Reisner, an Austrian colonel and military analyst, confirmed to the international press the success of the maneuvers, classifying the movement as a “successful advance” that changes the geometry of the battlefield. Segundo Reisner, Ukrainian troops not only recovered ground, but did so in a coordinated manner across multiple sectors, which prevented the effective regrouping of Russian defenses.
In Kupyansk, the situation was particularly favorable for Kiev. Local forces managed to reestablish control over around 90% of the territory that had previously been lost to Russian occupation. The reconquest of this infrastructure is considered crucial for supply logistics in the region, allowing a safer flow of equipment and ammunition to the front lines.
Combat tactics in the gray zone
In addition to the adversary’s technological failures, the Ukrainian army has refined its engagement tactics in so-called “gray zones.” Estas areas, characterized by the absence of full control by either side and high volatility, became effective traps for Russian assault units.
The strategy adopted involves calculated tactical permission, where Ukrainian defenders allow limited initial advances by small Russian units. Once these troops enter pre-determined perimeters, they become easy targets for rear-positioned combat drones, which operate without the interference previously generated by Russian satellite-linked systems.
This dynamic has transformed the front line into a permeable and lethal environment. The ability to attract and neutralize the enemy, combined with momentary superiority in communication and field intelligence, allowed Ucrânia to maximize damage to the adversary while minimizing its own losses during the retaking of territories.
Current scenario of territorial control
The war maintains a fluid character, with control of vast areas changing hands as the logistical and technological capabilities of each army fluctuate. Dados recent reports indicate that Moscou still maintains control, total or partial, over approximately 19.5% of the internationally recognized territory of Ucrânia. Este number represents a slight increase compared to the previous year, but the recent counteroffensive demonstrates that Russian consolidation is not definitive.
Importantly, a significant portion of this percentage includes the Crimeia peninsula and regions of
The recent episode reinforces the thesis that communication technology is as vital as firepower in contemporary warfare. The dependence on satellite systems and the vulnerability to cuts in these services have proven to be decisive factors that can alter the course of entire battles in a matter of days, requiring constant adaptation of military doctrines on both sides of the conflict.
