In a covert operation, Al Jazeera gained access to one of Ukraine's long-range drone units, tasked with striking strategic targets deep within Russian territory. Based in eastern Ukraine, the Kairos Battalion of Magyars Birds Brigade operates a fleet of drones that can travel up to 2,500km (1,553 miles), reaching cities like Moscow and St Petersburg. These one-way attack drones, produced domestically by the hundreds, have expanded Ukraine's war strategy beyond oil and gas targets, now including Russia's largest online retailer, Wildberries, accused of selling dual-use goods to the military. Ukrainian officials argue that these 'long-range sanctions' aim to inflict economic pressure, fear, and losses upon Russia, with three main objectives: instilling fear, causing business losses, and making Russians feel the harsh reality of war. As these drone strikes continue night after night, the crews remain hidden to avoid Russian reconnaissance, as each flash carries the risk of revealing their position. The soldiers' determination is driven by a clear understanding that they are defending their people and land, while the Russians seem to still question their reasons for the ongoing conflict.
