The attack confirms a rapidly developing mode of drone warfare, which the U.S. has clearly monopolized. However, due to the wide availability of drones — you can even buy them on Amazon — both sides of the Syrian conflict have been improvising drone technology. A video recently released by an al-Qaeda affiliate purports to show a drone landing on a Syrian military target. Another video shows small explosives dropped by Hezbollah on al-Qaeda-linked terror group al-Nusra near Aleppo, as reported by the Military Times.
