Fake video, used game engine to generate. So many obvious signs of fakery. Note that the sound of rounds hitting is synchronized with the flashes. Pity that real sound travels at about 330 m/s and hence there should be a delays of over second, not to mention how would one record it on a drone. Also capturing the flash from real military high explosive rounds requires a very high frame rate camera unlikely to have been installed on a drone. The explosions look like a game engine (Unreal Engine?) imitation of "Hollywood Explosions" (that use Diesel, Charcoal, and Ammonium Nitrate). So the video is not just fake, it is a really bad fake. A bit like the footage that comes out of the USA with respect to "mass shootings" and "terrorist bombings".l
Russia and China also generate fake videos but for different types of "fake news". They too have their own stylistic signatures, but different from the Hollywood ones. Russia and China mostly use the Unigine Engine. Some internationally produced "major motion pictures" have used both and more.
