So guys, I just wanted to make sure my information of Spartans is up-to-date and correct. So let's start. Spartan II's (MC, Noble 1-5)went through major experimental augmentations and wore Mark IV armor. Spartans III's (Noble 6)went through augmentation procedures that were more finalized and safer than the Spartan II's and wore Mark V armor. Spartan IV's went through less augmentation and were mass produced and wore Mark VI armor. That's what I know and any corrections are appreciated!
