Ukrainian President Volodymyr Zelenskyy has a right to choose who leads Ukraine's military and the United States will work effectively with his new military chief, Celeste Wallander, the assistant secretary of defense for international security affairs at the Pentagon, Reuters reported.

"President Zelenskyy is the president of his country and Ukraine, unlike Russia, has a democratic civilian control of the military," Pentagon’s representative said.

Wallander called Syrsky "an experienced, successful commander."

As previously reported, President of Ukraine Volodymyr Zelenskyy announced in an evening address that Oleksandr Syrsky had been appointed commander-in-Chief of the Armed Forces of Ukraine.
