While drones are most certainly nothing new, how they will fight future wars is most certainly novel. Chief of these means is through the addition of autonomous drone 'swarms' to many militaries worldwide.

Attack Drone Swarms Growing Globally

Nations across the globe are ensuring that they don't fall behind the curve in this new weaponized technology. France has Icarus, Spain has RAPAZ, Russia has Lightning, the UK has Blue Bear, and the UAE has N-Raven.

Armenia recently unveiled a swarming attack drone. And we know that China has a wide range of drone swarm projects ongoing. Of recent note, China successfully tested a swarm of 1000 drones. 

The US is most certainly not behind the curve with drones. Currently, the Marines are looking to incorporate a kamikaze drone swarm into their fighting capabilities. In contrast, the Army, the Air Force, the Navy, and DARPA are also crafting their own swarm projects.
