Hieu Dinh

"You shove one Banished AI into your neural matrix, and everyone panics!"

- Hieu Dinh

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

ONI service
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.

Shortly after the war in early 2553, Dinh took part in a recon mission to a desolate moon that ONI had dubbed Operation: INTERIOR EXILE. The goal of this mission was to set up a research facility to examine a dormant Forerunner terraforming vessel embedded in the moon's rocky terrain. After his initial recon assessment, Dinh recommend that the thee squads of ONI personnel travel by air under the cover of night to minimize risk of contact with local enemy forces. However, conflicting assessments resulted in a daytime insertion involving the use of an M12B Warthog. The insertion run resulted in disaster and agents Dinh and Padraig were among the few survivors. After the failed operation, ONI agent BAYLEAF communicated to fellow agent FLYBALL that it seemed that they should have listened to Dinh's recommendations and suggested that they consider accelerating other avenues to put him in a position where he could have a greater impact in planning these sorts of operations.

Spartan-IV service
Dinh would be recruited into the SPARTAN-IV program later in 2553, carrying the weight of the losses on the previous mission with him. As a new recruit, his fireteam was assigned a mission that had them breach and raid a fledgling Yanme'e hive inside of a derelict Forerunner structure. The raid was ultimately a disaster as well; Dinh escaped with severe wounds, but the rest of his team perished. 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. Later on, he would work alongside Laurette Agryna as they both earned experience as Spartans. After the rise of the Created, 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.

Camber
During the Created conflict, between 2559 and 2560, Spartans Dinh and Eklund were deployed to one of several Banished shipbreaking yards in the Chiltift Basin on Camber. This particular facility was a former UNSC fleet depot housing the hull of FFG-201 and taken under Banished control. Eklund and Dinh began scouting out the location, using intermittent dust storms as cover. At some point, the two Spartans spilt up, but planned to regroup and move deeper into the facility under the cover of the next dust storm. After watching the operation for two days, both Spartans discovered Iratus, the first Banished AI in existence, alongside an archive detailing all Banished operations on the moon. Eklund and Dinh were discovered by Banished forces and managed to hijack an Eklon'Dal Workshop 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, threatening his life.



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 bait, and trap Iratus into an ONI server. The plan was a success, and Iratus was trapped, saving Dinh's life. Following his recovery, Dinh met with Spartan Eklund at the firing range to talk about Iratus and the traumatic memories that he forced Dinh to relive. Eklund comforted him and urged him to ignore Iratus's words. She then introduced Dinh to one of the Spartan recruits who helped save his life. As she walked away, Dinh told Eklund to let Agryna know that he head is as good as ever, to which Eklund responded jokingly saying that maybe that's what she is worried about. After Eklund left the firing range, Dinh talked to the recruit and offered them his personal M392 Bandit as thanks, telling them to come find him once they get good with it. Before he walked away, Dinh told the recruit that the academy is old like him and that it has memories too.

Equipment
During the mission to the Yanme'e hive as a new Spartan-IV recruit, Hieu Dinh wore Mirage IIC armor. As of 2560, Dinh now 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. The helmet is equipped with a TAS/PATTON module. He wore the UTIL/TECCNIQE IOTA-12 on his left shoulder and a Banished war-trophy, the shoulder pad of a Spec Ops Sangheili's intrusion harness, on his right one. He also wore the AAP/HEARTPLATE chest attachment and the UA/Type MEP[B] knee pads. Dinh is known to regularly wield an M392 Bandit rifle in combat.

Trivia

 * Dinh's blood type is likely A+, as shown by a label on his helmet. This label is present on the default Artaius helmet.
