Multirotor in the context of "Drone warfare"

Drone warfare is a form of warfare that involves the deployment of military drones or military robots. The robots may be remote controlled by a pilot or have varying levels of autonomy during their mission. Types of robots include unmanned combat aerial vehicles (UCAV) or weaponized commercial unmanned aerial vehicles (UAV), unmanned surface vehicles (USV) or unmanned underwater vehicles (UUV), and unmanned ground vehicles (UGV).The applications of UAVs, UGVs, USVs, and UUVs are diverse, ranging from reconnaissance, kamikaze missions, bomb disposal, cargo transport, and medical evacuation to anti-air, anti-armor, and anti-personnel role. As of 2019, the following nations have been identified as having operational UCAVs: China, France, Greece, India, Iran, Iraq, Israel, Italy, Pakistan, Poland, Russia, South Korea, Turkey, the United States, the United Kingdom and Ukraine.

Drones find application in a variety of military operations, including electronic warfare, explosive ordnance disposal, training and logistics support. However, they are most frequently employed in intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) missions, enabling direct attacks on targets as part of a kill chain or through manned-unmanned teaming. Aerial drone attacks can be executed through the use of purpose-built UCAVs, that deploy ordnance during a drone strike, or by weaponized commercial UAVs that drop munitions or engage aerial assault. Heavy-lift drones may also be used to airlift supplies or evacuation of wounded personnel across a battlefield. Smaller drones, such as SUAVs and MAVs, are man-portable and can be deployed for low-altitude, short-range support operations. Larger drones can serve a "mothership" role by deploying smaller, sub-drones or by being equipped with electronic warfare features such as a signal repeater. Multiple drones can operate and attack simultaneously in a drone swarm and autonomous drones, such as LAWs, utilize military AI.
