Ukraine has undertaken the most significant simultaneous shake-up of its military and political defence leadership since the war began, replacing both Defence Minister Mykhailo Fedorov and Commander-in-Chief Oleksandr Syrskii within a single week — even as its armed forces deliver arguably their strongest battlefield performance in three years of fighting.
Fedorov was removed on July 15, with Syrskii following six days later. Several of their key deputies also departed. The move sparked street protests following Fedorov's ouster and appeared to stem from an internal strategic debate, particularly over the role of unmanned warfare in Ukraine's defence doctrine.
Leadership Overhaul Amid Strategic Debate
Ukraine has replaced defence ministers and commanders-in-chief before, but never simultaneously. The reshuffling came at a paradoxical moment: 2026 has become Russia's worst year of the war in terms of manpower losses, territorial gains, and domestic economic performance.
Speaking after Fedorov's removal, Syrskii pointed to "an effective strategy that is currently demonstrating concrete results." A day after his own departure, he wrote a column on the Militarnyi news website arguing that the defence minister should not serve as a war strategist. "War strategy, planning of operations, the situation on the front — by law, I am responsible to the Supreme Commander-in-Chief," Syrskii wrote.
Drone Warfare Divides the Command
The core disagreement between the two men centered on unmanned warfare. Syrskii established the world's first Unmanned Forces Command, known as the SBS, and oversaw what became the first war in which First Person View drones caused an estimated 95 percent of enemy casualties. Ukraine's medium and long-range drones have severely disrupted Russian logistics and oil supply lines.
Fedorov, during his six months in the role, aggressively expanded drone procurement — buying more in four months than the defence ministry had purchased in all of 2025, even diverting soldiers' payroll funds to increase orders. Syrskii pushed back, writing: "Against us is an enemy that is superior in everything, who fights, in particular, with artillery, aviation, and infantry. I cannot transfer a million-strong army 'to drones' in two months and say: now we are fighting like this."
President Volodymyr Zelenskyy, who recently told the Financial Times that "the sky will be decisive in this war," said on July 20 he was continuing to assess what adjustments should be made to Ukraine's defence strategy and production priorities.
Battlefield Gains and Disrupted Supply Lines
Ukraine's drone-centric strategy has produced measurable results. According to the Institute for the Study of War, a Washington-based think tank, Russia's net territorial gain for the year stands at just 81.1 square kilometers. June netted Russia only 30 square kilometers, and July has seen Russian forces suffering net territorial losses of 1.6 square kilometers per day.
Russia has suffered approximately 193,500 troops killed or seriously wounded, according to Ukraine's defence ministry — the first year averaging 32,000 losses per month. Ukraine's Foreign Intelligence Service estimates that Russia is now unable to meet its recruitment targets.
Since June 6, the commander of Ukraine's Unmanned Systems Forces, Robert Brovdi, reported that Ukraine had disabled 196 fuel tankers and destroyed three-quarters of Russia's ferry capacity across the Kerch Strait. Russia was forced to redeploy 200 units of its own unmanned forces command, called Rubicon, to protect an equal number of ships, weakening its frontline.
