The Third Army Corps said Russian forces lost around 2,000 men during the operation, while more than 250 Russian soldiers were taken prisoner. The body described Vivaldi’s third phase, or “season”, as a turning point in the wider operation.
The main objective of the third phase was Nove, which the corps described as a key Russian hub on the beachhead. The commander of the 3rd Army Corps, Brigadier General Andrii Biletskyi, said control of the surrounding heights was crucial to maintaining the initiative in the region.

“The enemy was convinced that the main direction of the attack was Shandryholove-Zelena Dolyna. This forced them to senselessly burn through their reserves during counterattacks precisely in this direction. The Russians missed the real strike, which was focused on capturing Nove,” Biletskyi said.
According to the corps, Ukrainian forces used modified Soviet-era BTR-60 armored personnel carriers to breach Russian defenses. The vehicles had been converted into remotely controlled ground strike systems and were used to destroy heavily fortified Russian positions.

During the first phase, Ukrainian forces cleared 75 square kilometers of Russian infiltration positions, regained control of several settlements, and reportedly inflicted substantial losses on Russian forces.

The operation also involved new approaches in the use of unmanned systems. On September 24, the Third Corps said it had carried out what it described as the first such attack involving unmanned ground vehicles deployed by heavy bomber drones.
According to the Corps, heavy bomber drones operated by the Third Assault Brigade carried NC13 strike UGVs, known as “Gryphons,” and deployed them more than 10 kilometers behind Russian lines.
