SPARTAN-B312 (Earth-2042)

"I aim to please."

- SPARTAN-B312

Lieutenant SPARTAN-B312 was a SPARTAN-III supersoldier attached to Special Warfare Group Three of the GRSC Army. During the Fall of Reach in summer 20 BBY, he served as a member of NOBLE Team under the call sign "Noble Six". Although unknown to most of the GRSC military and the Galactic Republic in general due to the classified nature of his operations, Doctor Catherine Halsey stated that B312 shared a "hyper-lethal" rating with only one other SPARTAN and served just as essential a role in securing humanity's victory in the Clone Wars.
