Ukraine forms two new National Guard corps led by Azov and Khartia brigade commanders

Ukraine’s National Guard has officially established two new military corps as part of sweeping defense reforms that seek to increase battlefield effectiveness amid the ongoing war with Russia’s invading forces, the service announced on April 15.
The newly formed corps will be headed by prominent and battle-hardened field commanders: Col. Denys “Redis” Prokopenko, commander of the 12th Azov Brigade, and Col. Ihor “Kornet” Obolenskyi, commander of the 13th Khartia Brigade.
Brig. Gen. Oleksandr Pivnenko, Commander of the National Guard, said the appointments are designed to improve unit cohesion by placing trusted leaders in charge of forces they know personally.
The reform aims to enhance flexibility, resilience, and battlefield coordination, reflecting lessons learned from Ukraine’s ongoing war with Russia. The move follows President Volodymyr Zelenskyy’s approval in February of a broader military reorganization transitioning from brigade- to corps-level command structures.

He served as a flamethrower operator in the fire support company of the 154th Battalion, military unit A7320.
“I’ve known Zhenia since childhood,” said family friend Iryna Spiridonova. “He was outgoing, full of life, always reliable and kind. He never turned away from a challenge and was always ready to help.”
