This was even a wire guided drone, they say, and a great step towards an Underground War instead of an Invasion.
Qualifying the target needed military intelligence or secret service reconnaissance. Then they used a standard battlefield drone.
In warfare, new tactics create new weapons most of the time and only sometimes new weapons created new tactics. This time a new weapon, modified civilian drones initially made to create stable pictures from a flying object having less shaking than an RC helicopter, were turned into flying bombs. Now, having gained understanding of their capabilities, new tactics arise and are field tested.
Targeted killings are very efficient. The take down of Deso Dogg sent a clear message to the European Gangster Rap scene to not be tempted joining ISIS. The Reaper Drones are different than these small Drones, but Drone kill is what sticks.
Soon, we will see drone rockets the size of a Speer or drones firing machine guns and progress in the tactics used making war more dangerous for even the most remote stakes.
The Crime World will quickly scale up their arsenal.
