Small unjammable drones controlled by fiber-optic cables have become so integral to Russian and Ukrainian combat operations that they are leaving trails of cabling everywhere, turning areas of the battlefield into a tangled web.
As a counter to extensive electronic warfare, fiber-optic drones are becoming increasingly prevalent on both sides. And with sprawling cables stretched across the battlefield, soldiers are moving with greater caution.
"You see the little webs, and you never know — is it from the fiber-optic drone? Or it's a part of a booby trap," Khyzhak, a Ukrainian special operator who for security reasons could only be identified by his call sign ("Predator" in Ukrainian), told Business Insider. Mines and traps have also been prominent threats in this war.
Earlier in the war, first-person-view (FPV) drones — small quadcopter-style drones fielded by both Russia and Ukraine that often carry explosive warheads — relied on radio-frequency connections. However, both sides quickly figured out how to use signal jamming to stop them.
