Ukrainian President Volodymyr Zelenskyy has dismissed General Oleksandr Syrskyi as commander-in-chief of the armed forces and appointed Major General Mykhailo Drapatyi in a sweeping response to public anger over military leadership.

The change followed days of protests in Kyiv and other cities. Demonstrators demanded Syrskyi's removal and criticised what they described as an outdated, Soviet-style command culture associated with heavy casualties and resistance to reform.

The demonstrations were triggered by Zelenskyy's earlier dismissal of defence minister Mykhailo Fedorov, a reform-minded and technology-focused figure who had publicly clashed with Syrskyi. Fedorov accused the general of obstructing changes that he believed were necessary to modernise Ukraine's military and preserve soldiers' lives.

Zelenskyy said the decision followed consultations with military commanders and that the structure of the General Staff would be reorganised. He praised Syrskyi's record in the defence of Kyiv and operations in Kharkiv and Kursk, while arguing that the war now required a new phase of leadership.

Drapatyi, 43, belongs to a generation of Ukrainian commanders whose reputations were forged after Russia's intervention in 2014. He became widely known for his role in a successful operation in Mariupol and later held senior commands during the full-scale invasion.

He has built support among parts of the military and civil society by speaking openly about reform, responsibility and the cost of institutional failure. In a recent statement, he argued that commanders have no right to remain silent when problems are measured in lost opportunities, time and human lives.

The new commander inherits an enormous task. Ukraine must hold a long front against a larger Russian force while managing ammunition shortages, mobilisation pressures, air-defence needs and the rapid expansion of drone warfare.

Zelenskyy has said the new leadership must update defence strategy, improve procurement, strengthen air defence and create conditions that pressure Russia toward peace. Those priorities overlap closely with the agenda associated with Fedorov.

The reshuffle is unusual because it came under visible street pressure during wartime. Thousands of Ukrainians, including veterans and soldiers on leave, joined demonstrations. The deputy commander of the air force also resigned in protest after Fedorov's dismissal, warning that the decision could weaken reform and air defence.

That public mobilisation shows how deeply questions of military governance now affect Ukrainian politics. Citizens who accept the necessity of national defence are also demanding accountability over how soldiers are led, equipped and protected.

Drapatyi's appointment may calm some of the unrest, but it does not resolve the underlying dispute. Ukraine's armed forces contain layers of bureaucracy, entrenched command habits and procurement problems that cannot be changed by one appointment.

The war is also continuing without pause. Russia launched further missiles and drones as the leadership change unfolded, underlining the danger of managing institutional reform while facing constant attack.

Changing the commander-in-chief is dramatic; changing the system that produced the crisis will be harder.

Drapatyi's success will be judged not only by territory held or recovered, but by whether the armed forces become faster, more transparent and more capable of preserving the people who carry the war.
