Years have passed since the events of Eternal Story and the war has had many losses on both sides. The Solnoid forces are so short on troops that cyborgs were created to handle dangerous assault missions and less-complicated technician roles. Cyborg soldiers pilot the Detonators and probably other attack craft. The cyborgs have organic materials inside their metallic shells but they are not sentient beings. Their AI minds are on the same level as service robots like Poil 1.
