'''O'Brien''' is a [[SPARTAN-IV Program|Spartan-IV supersoldier]]. She attended the [[Avery J. Johnson Academy of Military Science]].{{Ref/Level|Id=HITutorial|HInf|Tutorial (Halo Infinite)|Tutorial}}

==Biography==
O'Brien entered the [[SPARTAN-IV program]] as a recruit, where she was put through training at the [[Avery J. Johnson Academy of Military Science]]. O'Brien was later seen standing alone while Spartans [[Ionescu]], [[Denning]] and [[Page]] were socializing nearby. O'Brien took part in a [[Tutorial (Halo Infinite)|live-fire exercise]] in which she competed alongside Spartans [[Leung]], [[Eusebio]], and [[Denning]]. They faced off against Spartan Commander [[Laurette Agryna]], Spartans Ionescu and Page, and "[[Rook]]".{{Ref/Reuse|HITutorial}}

Months later, O'Brien was involved in [[Battle of Nysa|the defence of the academy]] against a [[Banished]] assault in early [[2560]]. On March 4, she joined Spartans [[Sigrid Eklund]] and [[Hieu Dinh]] in defending the base, engaging a [[Jiralhanae Berserker]] in close-quarters alongside [[Sinclair]]. The berserker knocked O'Brien unconscious and pinned her against a wall, before killing Sinclair and finally being put down by Eklund. Eklund and Dinh then retreated inside the base with an injured O'Brien and brought her to the base's [[Hospital corpsman|medics]] for aid. Her fate thereafter is unknown, as she was not present when Eklund and Dinh retreated into the base's AI lab.{{Ref/Reuse|BFTA2}}
