no, cause theres more than one master chief guy
-_- Masterchef wears a standerd issue suit, thats why they were able to put upgrades on it at the start of Halo 2 like it was nothing to upgrade it, whereas a one-and-only body suit probably wouldn't have upgrades like that.
My point is Masterchef was never thought of as more then an advanced warrior before you started playing as him, so what makes him so special as to get his own suit? I think I actually remember something from Halo 1 at the start where they say one of the other guys like Masterchef was damaged...probably wrong, I stopped playing Halo till I get Halo 3 :O
