The Burst Drone is a highly versatile, dragonfly-like machine that can fly rather quickly and can be used to scout out terrain before engaging a larger number of troops. It can also detect disguised or stealthed units.
The Burst Drone has the ability to attach itself to other vehicles or aircraft. This will slow the host vehicle down and also allow the Empire to scout enemy bases on their backs. Alternatively, they can also self-destruct, damaging the host vehicle as well as surrounding vehicles, making it useful when used in swarms. Since it is extremely quick, other units may not be able to destroy it before it attaches to a vehicle. For example, a few drones could easily overwhelm the Allied Athena Cannon.
In order to remove the Burst Drone from a vehicle or aircraft, it will have to be brought to a Soviet Crusher Crane, Allied Airbase, Seaport or Armor Facility, or the Empire of the Rising Sun's Imperial Docks or Mecha Bay. The drones are then removed when the factory drones repair the host unit. Light infantry units can remove them too.
They should always be approached with extreme caution. The best way to get rid of the drones is to set anti-air defenses against them. Since their armour is minimal, they can be destroyed easily.
