Ukrainian President Volodymyr Zelensky replaced his long-serving army chief, Oleksandr Syrsky, with joint forces commander Mykhailo Drapaty after weeks of protests.The move came following the removal of popular defence minister Mykhailo Fedorov, who accused Syrsky of blocking military reforms.Syrsky, who led Kyiv's defense during Russia's 2022 invasion, faced criticism for slow reforms and lack of transparency.Drapaty, a decorated general known for his 2014 Mariupol incident, is now in charge.The crisis highlights internal divisions within Ukraine's military and political leadership.Analysts note Syrsky wasn't a threat to Zelensky unlike his predecessor, but his management style sparked backlash.The change comes as Ukraine's forces continue to resist Russian advances, though recent aerial strikes have increased civilian casualties.Fedorov welcomed Drapaty's appointment, calling it a 'breath of fresh air' for Ukraine's military modernization efforts.
