Ukraine's 3rd Army Corps cleared 75 square kilometers of Russian infiltration groups and liberated another 10 square kilometers during the first phase of Operation Vivaldi in the Donetsk region. The offensive employed a coordinated electronic warfare dome combining signal jamming and ground robotics to disrupt more than 20,000 Russian UAV missions. The 3rd Army Corps assesses its electronic protection system as being roughly two years ahead of Russian equivalents.

Commander Andrii Biletskyi stated the operation ran for several months under strict information silence to maintain tactical surprise. Ukrainian forces are now crossing the Zherebets River as the military shifts from individual jammers to a coordinated battlefield layer intended to restore freedom of maneuver on drone-saturated fronts. This initial phase represents the first season of the broader operational concept.
