Drone warfare refers to the use of unmanned aerial vehicles (UAVs), commonly known as drones, for military operations including surveillance, reconnaissance, and combat missions. These remotely piloted or autonomous aircraft can gather intelligence, monitor enemy movements, and deliver precision strikes with minimal risk to human operators. Drone warfare has transformed modern conflict by enabling real-time data collection and targeted attacks, often from great distances. While drones offer strategic advantages, their use raises ethical and legal concerns, particularly regarding civilian casualties, privacy, and accountability. As technology advances, drone warfare continues to evolve, influencing military tactics and international security policies.
