Between 2511 and 2517, 150 five- to six-year-old children were selected from near perfect psychological and genetic markers that were set in Dr. Halsey's selection protocols. The children were screened for certain genetic markers: strength, agility, even predispositions for aggression and intellect. But due to lack of facilities and funding, only 75 children were chosen for the program. The other half of the 150 original candidates were "weeded out" possibly through "chance" and "luck," the single flip of a coin.
