The Combat Drone is the fast unit of the Tomorrow Era. The unit is built in a Combat Drone Base. These units have large bonus vs light units and very small bonus vs artillery units, but are vulnerable to both ranged units and heavy units. They do not have any terrain bonuses.
Flying unit: Cannot be attacked by artillery units. Ignores terrain when moving.
Just like its predecessor, Attack Helicopter, it has improved range, speed, attack, but it has decreased defense over the Attack Helicopter however. It similarly possesses the ability of Flying. A single Combat Drone can win infinite battles against eight artillery units without taking any damage.
It is the only fast unit that is able to attack enemy units with the Contact ability without retaliation. (Other units with this ability include the MG Team and the Anti-Aircraft Vehicle).
