Report claims 'V2U' drone swarm over Kharkiv during strikes

The strike log includes an unusual entry: "V2U" and specifically "a flock (staiyka) of V2U over Kharkiv," implying coordinated multi-drone employment rather than single Shahed/Geran launches. If accurate, this suggests a new or newly-noted UAV type/tactic (small-group/swarm usage) being used in the strike package.
