The chants echoed outside Ukraine's parliament in Kyiv before spreading to cities across the country.

Their signs carry two simple messages: “Bring Back Fedorov” and “Syrskyi Must Go.”

The crowds are protesting President Volodymyr Zelenskyy's 15 July decision to dismiss Defence Minister Mykhailo Fedorov. They are also demanding the removal of General Oleksandr Syrskyi, the commander-in-chief of Ukraine's armed forces.

According to several Ukrainian media reports, Fedorov's dismissal followed a power struggle with Syrskyi.

And just days after the demonstrations began, Zelenskyy yielded to the protesters' main demand, dismissing Syrskyi last night.

For many Ukrainians, the dispute was above all a generational one. Syrskyi represents the old guard. Sixty years old and trained in Soviet military academies, he is associated with a Soviet-style approach to warfare that many believe no longer fits the realities of the battlefield.

He commanded Kyiv's ground forces in 2022, helped drive Russian forces out of the Kharkiv region later that year, and oversaw Ukraine's incursion into Russia's Kursk region in 2024. He brings decades of expertise and credentials, but with it, an approach to war that some may say is outdated.

On the other hand, at the young age of 35, is Mykhailo Fedorov, the former minister for digital transformation who has become the face of a new generation within the Ukrainian state. One that innovates, iterates, and moves fast.

“I personally call him some kind of mini Elon Musk on Ukrainian soil,” Ivan Stupak, a Ukrainian politician and former officer of Ukraine’s intelligence services, told us.

“Mr. Fedorov is an iPhone 16 and Mr. Syrskyi is an old style phone, which is hung on the wall. Same purpose, different approach,” he continued.

Front line troops echoed this feeling to us, accusing Syrskyi of relying on tactics that wear down the enemy through prolonged fighting at the cost of heavy Ukrainian casualties, while resisting reforms that would give greater autonomy to drone units and accelerate military innovation.

Mini Elon Musk

Fedorov, in contrast, is the drone champion. During his brief tenure (129 working days) as defence minister, Fedorov expanded drone production and backed long-range strikes against Russian infrastructure.

In his previous role as minister for digital transformation, he launched Brave1, a procurement platform that allows brigades to order equipment directly from Ukrainian manufacturers, bypassing middlemen and reducing opportunities for corruption. While Ukrainian soldiers jokingly call it “the Amazon of drones,” Western militaries have been starstruck by the platform’s capabilities.

The battle of old versus new is at the centre of this public outrage. “People trust Fedorov and still trust his decisions,” said Stupak.

With that trust – and very little preemptive communication from Zelenskyy – the public is left to speculate as to the reasons for his being fired.

Zelenskyy publicly attributed the dismissal to the breakdown in relations between Fedorov and Syrskyi, with stalled mobilisation reform as a secondary reason. Stupak's sources believe the real rupture was personal, between Fedorov and Zelenskyy himself.

A people, outraged

This is only the second time that thousands of Ukrainians have taken to the streets against a decision made by Zelenskyy since Russia's full-scale invasion.

Last summer, protests erupted over a controversial law that curbed the independence of the country's anti-corruption agencies, ending in Zelenskyy eventually reversing course after days of public pressure. Many of the protesters gathering today hope their voices will once again force the president to reconsider.

Outside parliament, Denys, a veteran who lost a leg in the war, believes the difference between the two men is existential.

“Fedorov is the first defence minister to deliver real results on the battlefield,” he told us. “He understood that we cannot defeat Russia with more artillery. We need drones. Syrskyi belongs to another era. If we keep fighting this way, more soldiers will die.”

Kenin, a serving soldier, also sees the conflict as a generational one.

“Syrskyi was exactly the commander Ukraine needed in 2022,” he said. “But today's battlefield is different. Back then, artillery decided battles. Now drone operators do. If we don't adapt, we'll lose.”

In recent days, brigade commanders and officers have openly backed Fedorov on social media, accusing Syrskyi of slowing or blocking reforms. Their criticism is unusually public in a country where military disagreements are rarely aired during wartime.

Stupak believes that despite this decision, no matter where the reshuffle falls, Ukraine’s military will not feel the impact in the coming months, given that the immediate decisions have already been made and are now in motion.

A hit to morale

This has however opened a broader debate within the morale of Ukraine's armed forces that might otherwise have remained behind closed doors.

”Sometimes you risk your life for your country, and you end up wondering why,” said Bryce, an officer in Ukraine's military intelligence agency.

For him, the latest developments reflect a system in which ”good ideas are suffocated and competent people are prevented from succeeding.”

Zelenskyy now faces an unenviable choice. ”By removing Fedorov, he opened Pandora's box,” Volodymyr Fesenko, head of the Centre for Political Studies in Kyiv, told us.

Bringing Fedorov back would look like an admission of failure. Keeping him out risks deepening divisions within the military and across Ukrainian society.

”What Zelenskyy really needs,” Fesenko said, ”is a younger Syrskyi - someone more flexible, more open to change and closer to society.”

Fesenko's description sounded, at first, almost hypothetical. But within days, Zelenskyy made his choice, appointing 44-year-old Mykhailo Drapatyi to lead Ukraine's armed forces.

Among soldiers and military observers, Drapatyi is widely seen as one of the country's most capable battlefield commanders. Unlike his predecessor, he has consistently argued for giving frontline officers greater freedom to act, speeding up decision-making and reducing the army's reliance on rigid, top-down command. Following Fedorov's dismissal, he publicly defended the reform agenda.

His appointment is unlikely to end the divisions exposed by the protests, and it does not answer the question of Fedorov's future. But it does suggest that Zelenskyy has acknowledged the demands for change.
