Video Russian engineers have turned a humble drone into a formidable terrifying cataclysmic weapons platform, by, well, strapping a gun to it.

The flying gizmo was designed by Russian students in 2016, and completed this year, according to military blog C4ISRNET. Russia’s Federal Service for Intellectual Property later granted the patent to Almaz-Antey, a state-owned arms company.
