Using just careers and skills, not characteristics or profecience dice, what do you think the Master Chief would be (from the Halo series)?

Entertainer, with a focus on the fine dining experience.

Hah. Master chef would be an etertainer.

But Master Chief would be a lot of things. Commando? Heavy? Gadgeteer? Driver?

Definitely a Hired Gun. Brawl (or is it Melee to pistol whip?), Ranged Light, Vigilance, Discipline

I'd say it's then a toss up between Heavy and Mercenary Soldier. Hinges on what you use for your source material. If you go with all the EU stuff then he needs Leadership from the Merc. If it's just from the games alone then he probably is just a Heavy. Either way he's taking Ranged Heavy and then Gunnery/Leadership depending on which spec you pick.

I would say Tactician/Sharpshooter talent trees, with some jump boots, or FSEmergent with Enhance up the razoo.

Yes.

Pretty awesome and ridiculously expensive.

All of the things.
