Ukraine's Military Shake-Up Amid Strategic Gains Against Russia

In the middle of July, Ukraine made a decision that seemed to defy logic. Even as its military was performing better than it had in three years—inflicting record losses on Russian forces, grinding territorial advances to a halt, and crippling enemy supply lines—the country's leadership fired both its defence minister and its top military commander within six days of each other. The shake-up was unprecedented: no simultaneous replacement of this magnitude had occurred during the entire war.

Mykhailo Fedorov, the defence minister, was ousted on July 15. Six days later, Commander-in-chief Oleksandr Syrskii followed him out the door, along with several of their most senior subordinates. The timing seemed almost perverse. By every measurable standard, Ukraine's armed forces were winning. Russia had suffered approximately 193,500 troops killed or seriously wounded in 2026 alone—the first year the monthly average exceeded 32,000 casualties. The Institute for the Study of War, tracking territorial movements through open-source intelligence, found that Russia had netted only 81.1 square kilometers for the entire year. In June, that figure dropped to 30 square kilometers. By July, Russia was losing ground at a rate of 1.6 square kilometers per day. Meanwhile, Russia's war economy, which had surged in the years immediately after the 2022 invasion, had flatlined at 0.2 percent growth—a figure President Vladimir Putin himself acknowledged.

The removals, however, were not about failure. They were about strategy. The disagreement centered on unmanned warfare—specifically, how aggressively Ukraine should pivot toward drone-centric operations and how quickly resources should be diverted to that end. Fedorov had arrived at the defence ministry convinced that drones were the answer. In his six months in office, he purchased more unmanned systems than the entire defence ministry had acquired throughout 2025. He even diverted soldiers' payroll money to accelerate drone orders. Syrskii, by contrast, believed the shift was too radical and too fast. "Against us is an enemy that is superior in everything, who fights, in particular, with artillery, aviation, and infantry," he wrote after his ouster. "I cannot transfer a million-strong army 'to drones' in two months and say: now we are fighting like this."

Yet the evidence suggested Fedorov's instinct was correct. Ukraine had created the world's first Unmanned Forces Command, the SBS, and was fighting what appeared to be the first war in which First Person View drones accounted for an estimated 95 percent of enemy casualties. The results were tangible. By targeting Russian logistics—the supply routes running from Russia into the southern regions of Zaporizhia and Kherson—Ukraine had forced Russia to shift materiel and fuel across the Sea of Azov to Crimea. Ukraine then targeted those ships. Since early June, the commander of Ukraine's Unmanned Systems Forces, Robert Brovdi, reported that Ukrainian drones had disabled 196 fuel tankers and destroyed three-quarters of Russia's ferry capacity across the Kerch Strait, the narrow passage connecting Russia to Crimea. Russia had been forced to redeploy 200 units of its own unmanned forces to protect an equal number of vessels, weakening its frontline presence. In July alone, the SBS struck 117 electrical substations and power stations, mostly in Crimea, plunging much of the peninsula into darkness and forcing Moscow to earmark five billion rubles in compensation.

Ukraine's strikes extended far beyond the battlefield. Long-range drones destroyed a Tupolev-95 strategic bomber at an airfield 800 kilometers away and a MiG-29 fighter jet in Kursk. Ukrainian forces struck the Slavneft-Yanos refinery in Yaroslavl and, in an unusual shift, four warehouses belonging to the Wildberries online retail group, which Ukraine believed Russian recruits were using to order protective gear and weapons. The cumulative effect was to strangle Russian logistics while degrading Moscow's ability to sustain both its military and its domestic economy.

President Volodymyr Zelenskyy had recently told The Financial Times that "the sky will be decisive in this war," and his actions bore that out. The leadership changes signaled his commitment to the drone-first strategy, even if it meant removing commanders who had earned their positions through conventional military thinking. On the day after Syrskii's removal, he published a column arguing that the defence minister should not be a war strategist—that responsibility belonged to the commander-in-chief and ultimately to the president. The implication was clear: Zelenskyy was consolidating control over strategy and would not tolerate resistance to the unmanned warfare pivot.

Russia, meanwhile, was adapting in ways that suggested desperation. It had begun including ballistic missiles in almost every nightly strike on Ukrainian cities, a departure from its previous practice of concentrating missiles into one massive weekly barrage. Ukraine claimed to intercept 95 percent of drones and 87 percent of cruise missiles, but fewer than half of ballistic missiles. Analysis suggested Russia was burning through its missile reserves faster than it could replenish them, using more than its monthly production capacity in the first two weeks of July alone. The war was entering a new phase, one in which Ukraine's willingness to embrace technological innovation and reorganize its command structure at the moment of military success might prove decisive.
