Androïds #6

In order to forestall an alien invasion of Earth, a war will be fought on a distant planet... But the adversary, the Mantas, have the ability to mentally influence humans, and so the decision is made to counter the threat with an army of androids. Various classes are deployed, with the the superior class ‘Wander’ gifted with an augmented artificial intelligence. These androids do not know stress, fear, cold, fatigue... And they never rebel. Yet, in the combat zone, two units seem out of control. As unthinkable as it is... They are deserters!
