The Copter Drones and the Wing Drones are the only units in the game referred to in the plural.
Advantage: The large number of Copter Drones that can be deployed makes them a very big threat to the Flak Turretand Stinger ( both in and out of Watchtowers ) if they are spread out to form a 1/2 circle when Attacking. This allows the damage from these defenses to be limited to relatively a few units.
Disadvantage: Copter Drones have a roughly 1 sec pause in firing about every 3 sec. This allows defense units to either get into range or to come to a stop and fire.
In Game Graphics show the Copter Drones and other helicopters violently spin out of control and exploding when they are shot down.
The Copter Drone has 4 circular propellers, 2 "eyes", and 1 Machine Gun. The Reaper Drone has 2 circular propellers, 4 "eyes, and 2 Machine Guns.
