KYIV, Ukraine (AP) — Ukraine’s new military chief said Friday that his immediate goals are to improve the rotation of troops at the front lines and harness the power of new technology, at a time when Kyiv’s forces are largely on the defensive in the war with Russia.

Col. Gen. Oleksandr Syrskyi, who previously was the commander of Ukraine’s ground forces, spoke a day after President Volodymyr Zelenskyy put him in charge of the battlefield campaign with the war poised to enter its third year. He replaced the broadly popular Gen. Valerii Zaluzhnyi.

“New tasks are on the agenda,” Syrskyi said on his Telegram channel.

Though he provided little detail, his remarks appeared to align with Zelenskyy’s stated aim of bringing “renewal” to the armed forces with Thursday’s shake-up and adopting a fresh approach to the fight.
