Ukrainian soldiers from the Third Assault Brigade reportedly converted two Soviet armored personnel carriers (APCs) into unmanned ground vehicles packed with explosives, directing them at Russian positions in the Lyman region. The operation, dubbed "Vivaldi," took place near the settlements of Nove and Katerynivka.

The tactic involved repurposing the APCs as "Trojan APCs" filled with explosives to target Russian fortifications. The Third Assault Brigade shared details of the operation on social media platforms including Facebook, Instagram, X, TikTok, and YouTube.
