End of the Traditional Kill Chain Concept

When Abraham Karem pioneered modern drone technology in the 1970s, neither he nor the Israeli Air Force, with which he was closely associated, could have anticipated the transformative impact drones would have on modern warfare. Today, battlefield drones have demonstrated capabilities that challenge traditional notions of military superiority, as evidenced by the ongoing Russia–Ukraine war.

Ukraine’s strategy, which relies heavily on the extensive use of drones, has challenged Russia’s conventional military advantages, particularly its dependence on overwhelming firepower and artillery. In many instances, Russia’s reliance on massed firepower has been undermined by the unconventional and adaptive nature of Ukrainian drone operations, which have expanded the practical application of the traditional kill chain concept.

Rather than relying on rigid, top-down command structures, Ukrainian infantry units and specialized strike formations, such as Madyar’s Birds, operate with a high degree of autonomy. These units employ ad hoc networks to rapidly identify targets and deploy first-person-view (FPV) drones against logistics hubs, radar systems, and defensive positions before the enemy can react.

Since the beginning of the conflict, Ukraine has increasingly oriented its military doctrine around a network-centric warfare model that integrates weapons systems, intelligence assets, and command infrastructure into a unified information network. The primary objective of this approach is to shorten the kill chain, with drones serving as a critical enabling capability.

In confronting Russia’s military forces, the extensive use of artillery and 152 mm self-propelled howitzers, such as the 2S19 Msta-S, has effectively transformed the airspace extending approximately 10–35 kilometers from the front lines into a lethal “death zone” for both sides. This “kill zone” has made it increasingly difficult for Russian armored formations and massed troop concentrations to maneuver without being detected and targeted. In many respects, this development reflects the military doctrine advanced by Captain Basil Liddell Hart during the First World War, commonly known as the “Indirect Approach.”

The indirect approach advocates striking an opponent’s vulnerabilities through maneuver, deception, and surprise rather than confronting its strengths directly. At first glance, Ukraine’s extensive use of drones against Russia’s formidable firepower appears to challenge the strongest component of Moscow’s war machine. In practice, however, these operations exploit a critical vulnerability: Russia’s dependence on expensive........
