Laser vs. drone swarms

Drones may be fantastic as a consumer hobby, but these small unmanned aerial vehicles pose a significant security threat when they fall into the wrong hands. One weaponized drone is bad enough, but drone swarms are a security nightmare for military officials. Drones, whether alone or in groups, are difficult to spot when approaching, tough to follow on radar, and cannot be easily shot down using conventional weapons. To combat this potential threat, Lockheed Martin is developing a laser-based weapon that'll blow such drones out of the sky. Traditional military protocol relies on the use of missiles and guns fired from the ground or from ships or vehicle platforms.
