Katherine-B320 (Earth-5875)

"As a soldier in the field I couldn't possibly have access to those kinds of resources- that said, a good place to look might be... I don't know, the nearest nonexistent launch site in the nonexistent Sabre Program, dismissed by three administrations as preposterous rumor... And in which our newest memberwas certainly never a pilot."

- - Kat-B320 to Carter-A259

Lieutenant Commander Katherine-B320, better known as Kat, was a SPARTAN-III supersoldier of the UNSC Navy attached to the UNSC Marine Corps' Special Warfare Group Three. There, she fought at Noble Team under the callsign Noble Two as the unit's technology expert and the second-in-command of Commander Carter-A259.

Childhood and SPARTAN-III operations
Kat was born on January 30th, 2533, in Monastir, New Harmony. Her father, a UNSC Marine, was killed in action during the Shanxi Campaign and her mother died of an advanced malign cancer in 2536. Orphaned very young, she was raised by her grandmother, a retired Marine General. However, in 2540, following the fall of New Harmony to the Covenant, which led to the death of her grandmother, the Office of Naval Intelligence took the opportunity to "recruit" Kat as a part of the SPARTAN-III Program's Beta Company. Duo to her near inhuman skills with technology and computer programs, she was marked out for special assignment shortly after Project CHRYSANTHEMUM, only to be taken out of Beta Company's population by Lieutenant Kurt-051 and Master Chief Petty Officer Franklin Mendez, weeks before the disastrous Operation: TORPEDO.
