Military expert Alexander Zimovsky: I noticed the discussion about the flamethrower drone. Like, who owns the copyright? The flamethrower drone is such an ancient invention that you can buy it in America at any hardware store (Home Depot) for one and a half tons of green, along with a canister of mixture (3.8 l) as a gift. Horizontally it hits 7.5 meters. Vertically - to whomever God sends. Study it, the device is extremely primitive. Source: Victor vicktop55
