In halo 4, there is all this surprise and concern about how chief and the II's was kidnapped as a child and trained to be a spartan, while giving a crap load of ultra expensive equipment. But the III's were like 7 year old 'volunteers', who were basically thrown in the deep end, with cheap equipment and augmentations, then sent on suicide missions at around 12. Yet no one gives a -blam!- about them. At all. Kinda sad when you think about it.
