This is the terrifying moment a Ukrainian 'flamethrowing drone' set Russian defences alight with incendiaries that can burn up to 2,400C. Footage taken by another drone shows the flamethrower unit methodically tracing a forest understood to be hosting Russian troops, spitting hot thermite down below. The length of forest can be seen quickly catching alight, as smoke billows upwards. The video was posted by Ukraine’s 108th Separate Territorial Defense Brigade with a single word, referencing the dragons in Game of Thrones: 'Drakaris.'
