Oh really? Listen well Titan, they said Titans were modelled after Spartans, as Titan armor looks so immensely different from Mark V or VI armor that they would have had to model it after something else, such as E.V.A. Now, do I have your attention? Good. While Chief's armor may indeed resemble a Titans more than it does a Hunter's or a Warlocks, Hunters, in the official statement from Bungie were modelled after than man with no name(Clint Eastwood), and if you ever read the notes about who Master chief was based on, you'll find that guess what... He was based on the same person.
