An unprecedented simultaneous replacement of the top defence and military brass comes amid a debate over strategy. Ukraine replaced its top military and political defence personnel in the past week even as its armed forces arguably achieved their best performance in three years. Defence Minister Mykhailo Fedorov’s ouster on July 15 was followed six days later by the replacement of Commander-in-Chief Oleksandr Syrskii. Both men were followed out the door by some of their most capable lieutenants. Ukraine seemed to have found a winning formula, making 2026 Russia’s worst year of the war for manpower losses, territory and economic performance at home. Some 193,500 Russian troops have been killed or seriously wounded so far this year, said Ukraine’s Ministry of Defence – averaging losses of 32,000 a month for the first time, according to Syrskii – and Ukraine’s Foreign Intelligence Service estimates Moscow is unable to reach recruitment targets. This pain has produced a net gain of just 81.1sq km for Russia, according to the Institute for the Study of War, a Washington-based think tank that assesses territorial movements using geolocated open sources, and the trend of gains to losses is improving in Ukraine’s favour. If June was a disastrous month for the Russian operation, netting it just 30sq km, July has so far been worse, with Russian forces making net losses of 1.6sq km a day, according to the ISW. Meanwhile, Russia’s war economy, which boomed in 2022-24, has seen growth this year flatten at just 0.2 percent, Russian President Vladimir Putin admitted. Ukraine has replaced defence ministers and commanders-in-chief before, but this was the first simultaneous shake-up of the war and seems to have come amid an internal debate about strategy. On the day after Fedorov’s ouster, which produced street protests against the move, Syrskii spoke of “an effective strategy that is currently demonstrating concrete results”.

A day after his own sacking, Syrskii wrote a column on the Militarnyi news website saying, “The Minister should not … be a war strategist. This is not his task and not his responsibility.” “War strategy, planning of operations, the situation on the front — by law, I am responsible to the Supreme Commander-in-Chief,” he said. The nub of disagreement seems to have been unmanned warfare. Syrskii created the world’s first Unmanned Systems Forces, the SBS, and fought the world’s first war in which First Person View (FPV) drones caused an estimated 95 percent of enemy casualties. Ukraine’s middle and long-distance drones have devastated Russian logistics and oil supply, slackening the force it can deliver to the front. Fedorov pressed hard in this direction during his six months on the job, buying more drones in four months than the Defence Ministry had bought in all of 2025, and even spending soldiers’ payroll money to swell orders. Syrskii disagreed. “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,” he wrote on Militarnyi. Ukrainian 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 determine what adjustments should be made to Ukraine’s defence strategy and what priorities in production and supply to the military must be implemented as quickly as possible”. What is Ukraine doing that is working? Ukraine developed the use of short-range drones on the battlefield to reduce its own exposure and lower casualties. That strategy has yielded results, effectively halting Russia’s advance this year. Syrskii said Ukraine gained more territory than it lost in May, the month in which it began to strike Russian logistics using the overland route from Russia into its southern regions of Zaporizhia and Kherson.
