In a significant escalation of their conflict with Russia, Ukrainian forces have been using long-range drones to target strategic assets deep within Russian territory. These unmanned aerial vehicles (UAVs), produced domestically in large numbers, are striking targets such as oil refineries, factories, and warehouses, as well as online retailers like Wildberries, accused of selling dual-use goods to the Russian military. The campaign, which has expanded beyond energy infrastructure, is aimed at inflicting economic damage on Russia, causing fear among its population, and demonstrating Ukraine's resolve to defend its people and land. The drones, operated by a highly trained team, travel thousands of kilometers, avoiding cities to avoid detection, and rely on satellite navigation systems for guidance. While some Western allies have expressed concerns about the potential disruption of global energy markets, Ukrainian officials argue that these "long-range sanctions" are a means of enforcing the economic pressure that traditional sanctions have failed to deliver. As the war continues, both sides appear to be engaging in a tactical battle of endurance, with morale and professionalism playing crucial roles.
