The Spartan-II Candidates: Selection, Abduction, and Replacement

The Spartan-II candidates were chosen because they were children with extraordinary genetic, physical, and intellectual potential. They were also chosen because Catherine Halsey believed those traits made them more likely to survive the training and augmentations she intended to impose. This episode examines the selection process that identified seventy-five six-year-olds across human space and the covert operation that removed them from their families. ONI teams abducted the children and replaced them with flash clones designed to preserve secrecy. Those substitutes soon died from complications, leaving grieving families believing their children had succumbed to sudden illness. The deception protected the program while making the moral crime even larger. The real children were transported to Reach, assigned numbers, stripped of their former lives, and told they were being trained to protect humanity. They would eventually become heroes of the Covenant War, but nothing about that later necessity changes why they were originally taken.
