Who is Oleksandr Syrsky, Ukraine’s new top military commander?

Oleksandr Syrsky, appointed on Thursday as top commander of Ukraine’s armed forces, is credited with some of the most important battlefield successes since Russia’s full-scale invasion began, but is also associated with perhaps its biggest mistake — the costly defence of Bakhmut.

Born in 1965 in Vladimir, east of Moscow, Syrsky trained at the Higher Military Command School in the Russian capital — the Soviet equivalent of Sandhurst or West Point — and served in the army’s artillery corps.
