Videos have emerged showing Ukrainian armed forces unleashing a fleet of "dragon drones" in its conflict with Russia, reviving a weapon used in both World Wars with a modern twist. 

Videos shared on social media, including by the Ukrainian Defense Ministry, show low-flying drones dropping molten metal onto Russian-held positions, igniting trees and vegetation and potentially killing or disabling troops.

Thermite: A Devastating Incendiary Weapon

The drones deploy thermite, a mixture of aluminum powder and iron oxide, which burns at temperatures up to 4,000°F (2,200°C). This white-hot substance can quickly clear vegetation and potentially destroy Russian troops. As it falls from the drone, the thermite resembles fire from a mythical dragon's mouth, earning the drones their nickname.

'Wings of Vengeance'

Ukraine's 60th Mechanized Brigade hailed the drones as "wings of vengeance" and "a real threat to the enemy." The brigade noted that the drones can burn enemy positions with precision unmatched by other weapons. The use of thermite has previously disabled Russian tanks by igniting them through their hatches.

Controversial and Destructive Arsenal

Thermite is one of several incendiary weapons, including napalm and white phosphorus. The United Nations Office for Disarmament warns that these weapons can cause widespread destruction and environmental damage. While thermite is not banned for military use, its deployment on civilian targets is prohibited due to its horrific effects on the human body.

Humanitarian Concerns and International Law

Human Rights Watch has condemned incendiary weapons like thermite for their "horrific human cost," including inflicting severe burns and long-term physical and psychological damage. International law prohibits the use of thermite on civilian targets, but its use in combat is permitted.
