Ukrainian President Volodymyr Zelensky replaced another high-ranking army official leading troops in the country's embattled east on June 24.
During his address, Zelensky announced the sacking of the commander of the Joint Forces of Ukraine's Armed Forces.
Lieutenant-General Yuri Sodol has been replaced by Brigadier-General Andriy Hnatov in the post which involves strategic planning of operations.
Lt-Gen Sodol was reportedly accused of incompetence and abuse of power during the Russian invasion.
The move came as Kyiv has struggled to hold back Moscow's forces in the east for months, almost two and half years into the war.
