Ukraine pressed ahead with its fight against Russia Wednesday, hours after President Volodymyr Zelenskyy fired his top military commander in response to mounting public pressure.

Ukraine has made significant progress in the war this year and a rift between the country’s outgoing army chief and its defense minister threatened to derail its efforts. Both men lost their jobs following Zelenskyy’s major government reshuffle last week.

The new army chief, 43-year-old Maj. Gen. Mykhailo Drapatyi, belongs to a new generation of Ukrainian generals who have come up through the ranks during the battle against Russian aggression.

He became known for his daring and courage in 2014, the year that Russia seized and illegally annexed Ukraine's Crimean Peninsula – eight years before Moscow's all-out invasion.

Zelenskyy said Drapatyi and other commanders must present an updated defense strategy, including continued reform of the corps system, faster weapon and drone deliveries, stronger air defense against Russian strikes, and a clearer mobilization plan.
