Ukrainian Drones Are Modernizing Siege Warfare

Ukrainian forces are implementing a drone-based siege against Russian forces in Mariupol, disrupting broader Russian operations in the region. Located on the Sea of Azov, Mariupol is a key port and industrial center, vital to Ukraine's economy and Russia's land bridge between Crimea and the Donbas. Ukrainian drones are targeting fuel trucks, ammunition carriers, troop transports, and other logistics vehicles moving into and out of the city, degrading supply flows without a traditional ground encirclement.
