Hieu Dinh

Hieu Dinh is a SPARTAN-IV supersoldier serving under Commander Laurette Agryna.

Human-Covenant War
Hieu Dinh started his career as a field analyst for Section Three of the Office of Naval Intelligence. During the Human-Covenant War, ONI tasked him with capturing and re-purposing Covenant technology. Early in his career, Dinh and his fireteam were assigned a mission that had them breach and raid a fledgling Yanme'e hive inside a derelict Forerunner structure. The raid was ultimately a disaster; Dinh escaped with severe wounds, but the rest of his team perished.

Spartan-IV service
Dinh was left scarred by this experience in the Yanme'e hive, though his close call with death left him resilient in similarly-perilous scenarios. As such, he was recruited into the SPARTAN-IV program following the war, working alongside Laurette Agryna as they both earned experience as Spartans. During the Created conflict, Dinh fought against the Banished in several close-quarters engagements, including boarding actions. At some point, he would meet Spartan Sigrid Eklund during the Vihar collapse.

An opportunity to improvise
Between 2559 and 2560, Spartans Dinh and Eklund were deployed into a former UNSC fleet depot turned into a Banished shipbreaking yard on Camber during the Created conflict. After watching the operation for two days, both Spartans discovered Iratus, the first Banished AI in existence, alongside an archive with the entire Banished operation on the planet. Eklund and Dinh were discovered by Banished forces and managed to hijack a Banished Phantom, but Iratus followed them into their hijacked Phantom, threatening their escape. To have a chance to escape, Dinh allowed Iratus to infect his Neural interface, leaving him in a life threatening status.

Academy
Both Spartans managed to bring their Phantom into the Avery J. Johnson Academy of Military Science, where Eklund informed Spartan Commander Laurette Agryna about their operation on Camber. In an effort to pull Iratus out of Dinh's neural interface, Agryna uploaded a simulation of the Banished facility on Camber into the Academy's combat simulator, and assigned Spartans to participate in the simulation to act as a bait, and trap Iratus into an ONI server. The plan was a success, and Iratus was trapped, saving Dinh's life.

Equipment
Dinh employs the Mjolnir Rakshasa armor, shaped by his experiences against the Banished and surviving for long periods alone in the field in the wake of the rise of the Created. He wears an Artaius helmet taken from a small run of prototypes intended for a new classification of powered exoskeleton.
