Drone wars go underground and cross borders—what Israel and Russia are building next

On May 26, 2026, reporting from Ukraine highlighted how drone-dominated combat is pushing infantry operations underground. A company chief sergeant in Ukraine’s Khartiia Brigade, “Tovsty,” said that “you can’t really walk on the ground now,” and that movement and activity are increasingly conducted via subterranean routes. In parallel, another report described how Russia is exploiting an extensive network of Soviet-era underground infrastructure as a “drone-proof” corridor to advance troops. Together, the accounts suggest a tactical shift toward protected logistics and maneuver that reduces exposure to persistent ISR and loitering munitions. Strategically, the cluster points to a broader drone-and-counterdrone arms race across multiple theaters, with survivability and tempo becoming decisive. In southern Lebanon, Israel carried out eight air strikes hitting Khirbet Selm in the Bint Jbeil district, underscoring continued kinetic pressure in a contested border zone. At the same time, Elbit Systems’ CEO told Reuters that the company is developing hardware specifically to counter explosive Hezbollah drones, potentially including laser-based defenses, indicating that Israel is trying to blunt a lethal drone threat to its troops. On the Russian side, the emphasis on underground mobility and new sensing capabilities (radar and satellite monitoring) suggests Moscow is investing in both physical resilience and information dominance to sustain pressure. Market and economic implications cluster around defense technology, surveillance, and the enabling supply chains for air defense and counter-UAS systems. Elbit Systems’ stated development work reinforces demand signals for counter-drone components, laser/optical defense subsystems, and battlefield sensing, which can support sentiment across defense electronics and radar suppliers. Russia’s showcased Garmon-ME radar—capable of detecting air targets up to 60 km and operating in counter-battery mode—adds to the narrative of continued procurement for layered air defense and artillery-detection ecosystems. While the articles do not provide direct commodity price moves, the operational tempo implied by drone warfare can raise risk premia for defense-related equities and increase near-term demand expectations for ISR, communications, and protective infrastructure engineering. What to watch next is whether these tactical adaptations translate into measurable changes in battlefield outcomes and cross-border escalation. For Lebanon, monitor whether strikes around Bint Jbeil and other southern towns are followed by sustained drone launches or by a visible reduction in Hezbollah drone effectiveness after any deployment of new counter-UAS hardware. For Ukraine, key indicators include reported increases in underground corridor usage, changes in casualty patterns, and evidence of Russian success or failure in using Soviet-era tunnels to outmaneuver drone coverage. For Russia, track integration milestones for its satellite constellation data into the Unified Digital Services Platform and any further public demonstrations of radar performance, as these can correlate with improved targeting cycles. Escalation risk rises if counterdrone systems fail to keep pace with drone proliferation; de-escalation becomes more plausible if both sides demonstrate credible defensive effectiveness that reduces the incentive for mass drone attacks.

Geopolitical Implications

• 01

  Counter-drone capability is becoming a strategic determinant of operational tempo, pushing states to invest in layered air defense and directed-energy options.

• 02

  Underground infrastructure reuse (Soviet-era tunnels) may reshape ground maneuver doctrines, complicating targeting and increasing the value of ISR and counter-infiltration.

• 03

  Cross-theater technology convergence is visible: drones, radar, and space-enabled monitoring are reinforcing each other across Ukraine, Lebanon, and broader regional security dynamics.

• 04

  Continued strikes in southern Lebanon alongside drone-focused procurement increases the risk of localized escalation and sustained cross-border tit-for-tat.
