well i know what u mean by the s standing for spartans! but didn't ackerson hate dr hasley so i dont think he would call his project spartans aswell! most likely it does stand for spartans tho! i jst hate the people coming up with stuff like its forerunner guys in the new armor! even tho they are supposed to be whiped out thousands of years ago! and the different armor has to be new and upgraded! why would thay send people in older armor that is crap and outdated! come on its obvioulsy for ackerson's team! and for the guy in the different armor looking smaller than the other spartans is maybe because its a drawing and not to scale! and the fact he's crouching may have somthing to do with him looking smaller and he's BEHIND the spartan, meaning farther away from view as in smaller looking!
