Ukraine introduced a new and ingenious lethal weapon to the battlefield this week, one that so far the Russians have no answer for. Source: Business Insider Ukrainian forces appear to be increasingly using drones to rain a fire-like substance down on Russian troop positions in the tree lines, newly released combat footage shows. Multiple Ukrainian units have shared videos this week of their drones dispersing an incendiary material identified as molten thermite, which is essentially tiny pieces of metal burning at temperatures that can reach up to 4,000 degrees Fahrenheit. The scorching-hot substance can melt through metal, meaning it can be incredibly damaging when used against some armored vehicles.
