This article explores how these “sleeper drones” work, why they're hard to stop, and what challenges they pose for Ukrainian defenses. Russia is increasingly. In a significant leap forward for battlefield technology, Ukrainian company 3DTech has successfully codified its line of “Khyzhak REBOFF” fiber-optic unmanned aerial systems (UAS) with the Ministry of Defence. posted 06/07/2025 from the Ukraine Russian war - S.
