I see some videos and article on the internet that some Big countries like the United Kingdom and the United States are using drones for their military exercises and surveillance some area.
There are so many country that are using drones for their surveillance especially when it comes to combat.
this will make their soldiers secured because of the defense missile of the opponent.
this is very basic now a days for them.
I've also seen some videos of A.I Drone usage on military combat where anyone can be targetted by this mini-drones that have artillery equipped. It's a little bit scary what drone being used on military and police missions.
