Inside Ukraine’s Operation Vivaldi That Sees Its Troops Gaining Ground In The East

The War Zone | Howard Altman

Ukrainian forces from the Third Army Corps regained 125 square kilometres of territory near Lyman in Donetsk Oblast during Operation Vivaldi. Spearheaded by Brig. Gen. Andriy Biletsky, the counteroffensive demonstrated how structural command reforms can overcome persistent frontline infiltration by Russian mechanized forces. Commanders abandoned rigid Soviet-era leadership models to streamline tactical decision-making cycles and empower non-commissioned officers across degraded subordinate brigades.

This operational overhaul allowed Ukrainian forces to stabilize forward positions, integrate Special Operations Forces and Defense Intelligence units, and stockpile critical strike munitions. Unmanned aerial systems targeted Russian fuel depots and supply pipelines, forcing enemy logistics to re-route prior to Ukrainian ground maneuvers. Russian units retreated toward the Zherebets River. Simultaneously, President Volodymyr Zelensky reported to the United Nations General Assembly that Russian forces suffered 248,964 casualties in eight months, despite launching over 2,100 missiles and 7,700 jet-powered Shahed drones against Ukrainian infrastructure.

Comment

The structural transition within the Third Army Corps replaced centralized command hierarchies with decentralized tactical decision-making. By shortening the decision loop between reconnaissance drone operators and frontline commanders during Operation Vivaldi, Ukrainian units neutralised Russian infiltration before establishing offensive momentum. Decentralised authority enabled lower-level non-commissioned officers to exploit localized vulnerabilities near Lyman without awaiting higher-headquarters approval.

This tactical responsiveness relied directly on real-time sensor integration across attached formations, including Special Operations Forces and Defense Intelligence assets. Joint tactical headquarters consolidated surveillance streams to synchronise FPV drone strikes against Russian fuel routes along the Zherebets River. Consequently, the Third Army Corps disrupted the logistical sustainment of the 144th Motorized Rifle Division prior to launching ground assaults.

Strategic Question for Discussion

If the Third Army Corps' model of decentralized command in Operation Vivaldi is scaled across other Ukrainian sectors, which factor will constrain its effectiveness more — the availability of experienced NCOs or the continuous availability of tactical drone communications?

The operational evidence indicates that the primary bottleneck will be maintaining resilient tactical communications under heavy electronic warfare rather than cadre numbers. While NCO leadership can be cultivated through targeted command reforms, maintaining unbroken drone-to-command sensor loops across heavily jammed sectors remains extraordinarily vulnerable to Russian electronic countermeasures. Consequently, decentralized command structures risk fragmentation if local communications links are systematically severed.
