Ukraine's Vivaldi operation uses remote-controlled explosive vehicle to retake territory near Lyman

Ukraine's long-hidden operation Vivaldi near Lyman, Donetsk, employed a remotely controlled armored vehicle packed with explosives, contributing to the liberation of a significant part of occupied territory for the first time in a while. The novelty of the weapon suggests a tactical innovation, but details on the extent of the gains and Russian response remain unclear. This marks a notable shift in Ukraine's offensive capability, potentially impacting the conflict's trajectory.
