Ukraine’s Operation Vivaldi Shows Tanks Still Matter — With New Rules

Ukraine’s Operation Vivaldi shows that tanks and armored vehicles can still be used in a drone-heavy war, according to Business Insider’s reporting. The key shift is that armored assaults now require far more planning, coordination, and support than earlier battlefield models assumed. Drones, mines, and artillery have made large mechanized attacks harder and riskier, but the operation suggests they are not impossible.

Ukrainian forces involved in Operation Vivaldi carried out two successful mechanized assaults behind Russian lines, according to the report. The counteroffensive has so far taken back 277 square kilometers of territory. George Barros of the Institute for the Study of War told Business Insider the operation appears to be “the first successful mechanized tactical level breakthrough in a drone-dominated battlefield.”

The reporting points to detailed preparation as the decisive factor. Mission planning included separate training for vehicle crews and infantry, additional equipment for vehicles, and extensive support to shield the advance. Brigadier General Andrii Biletskyi said using armored vehicles is now “effectively a special operation,” requiring coordination across a large number of assets.

The challenge now is whether Ukraine can replicate these tactics beyond the Third Army Corps, which Business Insider describes as Vivaldi’s lead unit. The operation also fits a broader trend identified by ISW: Ukraine has been reintroducing limited mechanized maneuver through improved planning, suppression of Russian air defenses, and an emerging drone advantage. The practical takeaway is clear: tanks may still matter, but they need to operate as part of a wider force mix that includes drones, robots, sensors, and other support systems.
