Ukrainian forces are using fiber-optic drones in new deceptive tactics on the battlefield, according to a soldier and analyst with Ukraine’s 413th Unmanned Systems Regiment “RAID.” These drones, which transmit data via a thin cable resistant to electronic jamming, are being employed not only for surveillance but also to execute ambushes by lying in wait before detonating at opportune moments.
The drones’ resistance to electronic warfare has made them a critical tool for both sides in the conflict, enabling troops to conduct close-range reconnaissance and gather high-quality intelligence on Russian positions. Dmytro “Liber” Zhluktenko, a former drone operator and current analyst, described how operators are using the drones in atypical ways to “create tons of chaos.” This includes positioning drones to appear inactive before detonating to kill approaching soldiers or expose enemy fortifications.
One key application is studying Russian bunkers and dugouts. The drones provide high-resolution footage of entrances, allowing Ukrainian forces to assess defensive structures and plan targeted strikes. Zhluktenko noted that operators can determine the type of cover used at entry points and identify weaknesses before launching attacks. The drones’ ability to operate at close range offers precise intelligence that is difficult to obtain through other means.
While fiber-optic drones are effective for reconnaissance and ambush tactics, they have limitations. Their tethered design makes them slower than untethered FPV drones, and the fiber-optic cables can break under high stress, such as when accelerating rapidly. Despite these drawbacks, their resistance to jamming and ability to deliver real-time video feeds have made them indispensable for frontline operations.
The use of these drones reflects broader trends in modern warfare, where unmanned systems play an increasingly central role in both surveillance and combat. Their deployment underscores the evolving nature of battlefield tactics as militaries adapt to electronic warfare threats and seek innovative ways to gain tactical advantages.
