==Biography==
===Childhood and conscription===
{{Quote|I was actually an orphan myself, but yes, that's an excellent side effect.|Jun-A266, in reference to the SPARTAN-IV program not using children{{Ref/Reuse|NB7}}}}
Jun was born on [[2524|February 28, 2524]] in the city of [[Tyumen]] on the [[human]] [[Human colonies|colony]] of [[New Harmony]], approximately a year prior to the outbreak of the [[Human-Covenant War]].{{Ref/Reuse|universe}}{{Ref/Site|Id=profile|URL=http://halo.bungie.net/projects/reach/article.aspx?ucc=personnel&cid=24522|Site=Bungie.net|Page=Halo: Reach - Intel - Jun-A266 Profile|D=12|M=10|Y=2014|LocalArchive=Noble Team performance reports}} Through unspecified circumstances, Jun was orphaned at a young age.{{Ref/Reuse|NB7}} Under the direction of [[UNSC Army]] [[Colonel]] [[James Ackerson]], Jun was conscripted into the [[SPARTAN-III program]] by [[2532#December|December 27, 2532]] and brought to [[Onyx]], a world classified by the [[UNSC Navy]]'s [[Office of Naval Intelligence]].{{Ref/Site|Id=spartan3s|URL=https://www.halowaypoint.com/en-us/universe/factions/spartans|Site=Halo Waypoint|Page=Spartans|D=31|M=05|Y=2021}} One of the youngest orphans conscripted into the program, Jun was trained by [[Lieutenant Commander]] [[Kurt Ambrose]] and [[Senior Chief Petty Officer]] [[Franklin Mendez]] as part of [[SPARTAN-III Alpha Company|Alpha Company]] at [[Camp Currahee]]. During his training, Jun proved to be an expert marksman and seasoned scout.{{Ref/Reuse|universe}}

In [[2536]], Jun and the other Spartan-IIIs of Alpha Company underwent [[Project CHRYSANTHEMUM|physical augmentations]] aboard {{UNSCShip|Hopeful}},{{Ref/Marketing|HR|Remember Reach|Birth of a Spartan}} though complications with Jun's augmentations nearly crippled him. Nonetheless, Jun recovered and graduated from training alongside his peers in late 2536, at the age of twelve.{{Ref/Reuse|universe}}

===Early military career===
[[File:HINF WU Intel - Jun-A266 and Hazel-A302.png|thumb|250px|Jun-A266 and Hazel-A302, both Headhunters.]]
{{Quote|By my estimation Jun is a rationalist. He is also a Spartan.|Colonel Urban Holland during his evaluation of Jun-A266's military career{{Ref/Reuse|profile}}}}
Following his graduation, the Spartan-IIIs were placed under the authority of the Navy's [[Naval Special Weapons]] within the [[UNSC Special Forces]]. Jun proved to be one of the Spartan-IIIs' best assets, standing out from his peers within Alpha Company and attracting the attention of Kurt and Mendez. Like a number of other Spartans who showed particular promise, Jun was removed from Alpha Company's mainline deployment roster and his skill as a sniper soon had him leading a [[Headhunters|Headhunter]] team conducting missions directly for the Office of Naval Intelligence. Though he rarely speaks of this period, his performance was exemplary, as Jun was responsible for tracking down and assassinating a number of [[insurrectionist]] leaders who broke the tentative ceasefire between the UNSC and insurgent factions after the [[Covenant]] [[First Battle of Harvest|attacked]] the [[Outer Colony]] of [[Harvest]] in [[2525]].{{Ref/Reuse|universe}} Because of his special assignment, Jun and a handful of other Spartans did not accompany most of Alpha Company to their demise in [[Operation: PROMETHEUS]],{{Ref/Site|Id=reports|URL=http://halo.bungie.net/projects/reach/article.aspx?ucc=personnel&cid=24040|Site=Bungie.net|Page=Halo: Reach - Intel - Personnel|D=13|M=10|Y=2014|LocalArchive=Noble Team performance reports}} something deliberately arranged by the AI [[Deep Winter]] to try and save a number of Spartans (including others such as [[Hazel-A302]] and [[Kevin-A282]]) from the upcoming slaughter of PROMETHEUS. Deep Winter posed as Kurt to arrange Jun's reassignment as a Headhunter, and only revealed this deception at the end of his operational lifespan in [[2551]].{{Ref/Reuse|WUIntel}}

Attaining the rank of [[Warrant Officer]], Jun was reassigned to the Army's [[Special Warfare Group Three]] under the [[Unified Special Warfare Command]] as a member of [[NOBLE Team]], an elite [[fireteam]] of Spartans led by [[Commander]] [[Carter-A259]] and also consisting of Lieutenant Commander [[Catherine-B320]] as the team's second in command. Jun was personally selected as the team's sniper and scout by Carter.{{Ref/Reuse|carter}} With Jun holding the [[call sign]] of "Noble Three", NOBLE Team operated under the command of Colonel [[Urban Holland]], aiding Army teams in [[operation]]s throughout the [[Inner Colonies]].{{Ref/Reuse|reports}}{{Ref/Book|Id=gc|Halo: Ground Command core rulebook|Page=12}} Throughout these engagements, Jun was one of the few members to consistently make it back as part of the team, along with Carter and Kat.{{Ref/Reuse|gi}} 

===Later career===
====Concord====
{{Main|Defense of Concord}}
In late [[2551]], NOBLE Team were deployed to the colony world of [[Concord]] to assist in the planet's defence against the Covenant threat, working alongside the [[UNSC Army Rangers]] and [[Concordian militia]] forces across the planet. By 1405 [[Military Standard Time|MST]] on December 12, the [[D77 Pelican|Pelican]] dropship ferrying the team had been downed in the [[Hinterlands region]] of Concord following a snowstorm, resulting in NOBLE making their way to the remote township of [[Skathi]] on foot. While in Skathi, Jun operated in his usual role as a scout-sniper to keep watch on the massing Covenant ground forces stranded on the planet after the destruction of their invasion fleet by the UNSC Navy. After reporting a force consisting of a {{Pattern|Zashk|Draugr}} and a number of [[Wraith]]s and [[Ghost]]s to the rest of NOBLE, he stayed behind in Skathi to assist in the town's defence while Kat, [[Thom-A293]], and [[Rosenda-A344]] headed out to [[Operation: OFFSET EYE|meet the enemy attack]] in the field. As such, when the invasion force's [[Banshee]] escort advanced to the town ahead of the ground force, Jun was involved in the battle there alongside Carter and [[Jorge-052]].{{Ref/Novel|Id=WC|Halo: Winter Contention}}

By the time Kat, Thom, and Rosenda returned around 2100 MST, NOBLE Team were assigned a new set of orders from Colonel [[Urban Holland]]. With intelligence reports of Covenant forces massing in the [[Volanus system]], NOBLE was retasked to the colony of [[Fumirole]] in the hopes of intercepting a potentially inbound enemy attack there. While Rosenda was reassigned away from NOBLE, Jun was one of the team members kept on the team for the upcoming engagement at Fumirole.{{Ref/Reuse|WC}}

====Fumirole====
[[File:HRA-HUD.png|thumb|250px|Jun's [[HUD]] during the Battle of Fumirole]]
The [[Battle of Fumirole]] took place four months after Concord, in [[2552#April|April 2552]]. On [[2552#April|April 22, 2552]], NOBLE Team was involved in a plan set out by Kat to infiltrate and destroy the {{Pattern|Ket|battlecruiser}} ''[[Sanctity of Purification]]'', which had taken position over the planet's capital city. Kat's plan involved planting a [[Fury tactical nuclear weapon]] near the carrier, while Jun and the other Spartans provided covering fire alongside UNSC Army forces. However, the plan went awry when Kat was injured, leading to Thom sacrificing himself to destroy the [[warship]] with the nuke from within.{{Ref/Marketing|HR|Remember Reach|Deliver Hope}} Following Thom's death, the team was assigned to the Inner Colony of [[Reach]] in the [[Epsilon Eridani system]] to hunt down an off-world rebel leader,{{Ref/Reuse|gc}} where Thom was eventually replaced as "Noble Six" on the team by [[SPARTAN-B312]] months later on [[2552#July|July 24, 2552]].{{Ref/Reuse|actual}}

====Reach====
{{Quote|That's no strike force, it's an invading army. If we're gonna smother this thing, we need to go in hard and fast.|Jun discovering the Covenant occupational forces{{Ref/Level|Id=nightfall|HR|Reach:Nightfall|Nightfall}}}}
That day, NOBLE Team was sent to investigate a disturbance at the [[Visegrád Relay]] on Reach. During the operation, Jun spotted targets for the team from a [[UH-144 Falcon]], providing intel on enemy and friendly troop deployments. After they were engaged by Covenant forces, Jun, Emile, and Kat flew directly to the relay to get it operational and send a message to Holland, informing him that the Covenant had [[Fall of Reach|discovered]] Reach.{{Ref/Level|Id=winter contingency|HR|Reach:Winter Contingency|Winter Contingency}} Two days later, the team was deployed to defend ONI's [[Sword Base]] near the [[Babd Catha Ice Shelf]], which was under attack by Covenant forces. While Kat and SPARTAN-B312 were defending the base's exterior, Jun and the rest of the team made their way to the base's main atrium. After the main threat was neutralized, the team was debriefed by Doctor [[Catherine Halsey]].{{Ref/Level|HR|Reach:ONI: Sword Base|ONI: Sword Base}}

[[File:Staging area.png|thumb|250px|Jun and Noble Six overlooking a Covenant encampment]]

On [[2552#August|August 12]], Jun and Noble Six, designated [[Recon Team Bravo]], participated in a reconnaissance operation to assess the Covenant force deployments in the [[Viery Territory]] on Reach, with some support from the [[Reach militia|local militia]]. They made their way through several Covenant outposts and discovered a Covenant [[stealth pylon]], to which Jun planted an [[Unidentified UNSC explosive|explosive charge]]. They then proceeded further into Covenant-occupied territory and discovered a massive Covenant ground force deployed by the [[Fleet of Valiant Prudence]] massing on a plain in the valley below. They informed Command and mounted a counter-attack the next morning.{{Ref/Reuse|nightfall}}

Afterward, NOBLE Team split up, performing different operations to defend the planet. When most of the NOBLE Team members went to [[Farkas Lake]] to initiate [[Operation: UPPER CUT]] to destroy {{Pattern|Sh'wada|supercarrier}} ''[[Long Night of Solace]]'', Jun, in a Falcon, extracted Carter and Kat from the [[FSS-1000 Sabre]] [[Sabre Program Launch/Research Range|launch facility]] while Jorge and Noble Six participated further in the operation. While the operation proved successful, Jorge died when he sacrificed himself to blow up the supercarrier from within. Although Jorge's death meant the destruction of the largest and deadliest ship ever encountered by the UNSC (the hitherto-only CSO-Supercarrier ever encountered,) a much larger [[Covenant fleet]] arrived at Reach directly after.{{Ref/Level|Id=lnos|HR|Reach:Long Night of Solace|Long Night of Solace}} Jun participated in the following [[Siege of New Alexandria|Siege]] of [[New Alexandria]] on August 23. He and NOBLE Team later regrouped in the now-compromised [[Olympic Tower]] in the city, where Holland assigned the Spartans were destroying Sword Base which the Covenant now occupied. Just then, the Covenant began [[glassing]] the city dangerously close to NOBLE Team's position. As the Spartans fled, Kat was killed by a [[Sangheili]] marksman, [[Sangheili Field Marshal|Field Marshal]] [[Orsu Lar 'Ahtalee]]. The survivors attempted to kill the Sangheili, to no avail. On August 26, NOBLE Team emerged from a fallout bunker beneath the ruins of the Olympic Tower to be picked up by a Pelican.{{Ref/Level|Id=newalex|HR|Reach:New Alexandria|New Alexandria}}
[[File:JunThePackage.jpg|thumb|250px|left|Jun takes aim outside SWORD Base]]

On August 29, the remaining members of NOBLE Team arrived at the Covenant-occupied remnants of Sword Base; they were to demolish the base in order to prevent Halsey's excavation data from falling into Covenant hands. Jun, Emile, and Carter remained in a Falcon while Noble Six and a team of [[Orbital Drop Shock Troopers]] eliminated a pair of {{Pattern|Cheru|Tyrant}} anti-aircraft emplacements. After the cannons were disabled, NOBLE Team fought their way into the interior of the base. Once they arrived at the designated coordinates, which seemed to be a dead end with no load-bearing structures, [[dumb AI]] [[Auntie Dot]] revealed that the team had been given a new objective. They were to rendezvous with Halsey over a kilometer away and two thousand feet below ground. The team soon arrived at the crash site of a [[Forerunner]] [[Babd Catha Forerunner vessel|vessel]] beneath the ice shelf. Halsey insisted upon the importance of the site and demanded NOBLE Team's support while she completed transferring critical data in her laboratory. Jun and the other Spartans defended Halsey's lab from several waves of Covenant forces, who had found an entrance to the ruins. Eventually, Halsey ushered the Spartans inside, where she revealed the data she had transferred: a fragment of the "[[Smart AI|smart]]" [[artificial intelligence]] [[Cortana]] that carried a "latchkey" discovery found from within the ruins. She ordered NOBLE Team to escort the package to {{UNSCShip|Pillar of Autumn}}, a {{Class|Halcyon|light cruiser}} that was drydocked at the [[Asźod ship breaking yards|ship-breaking yards]] in [[Asźod]] preparing to depart from the planet.{{Ref/Level|Id=pack|HR|Reach:The Package|The Package}}

Once the team emerged from the cavern below Sword Base, Carter had Jun escort Halsey to the relative safety of ONI's [[CASTLE Base]]. Jun was ordered to protect Halsey and prevent the secrets she possessed from falling into Covenant hands.{{Ref/Reuse|pack}} Once Halsey was safely secured at CASTLE facility, Jun was then tasked with escorting CASTLE's own base staff to safe evacuation while Halsey stayed behind at CASTLE to enact Operation WHITE GLOVE on CASTLE Base herself.{{Ref/Reuse|WUIntel}} By the time Spartan-II [[Red Team]] arrived at CASTLE the following day, Jun was no longer present at the facility.{{Ref/Novel|HFS|Chapter=12}}

At some point just before the fall of the planet, he first encountered [[Gunnery Sergeant]] [[Edward Buck]] of the [[11th Shock Troops Battalion]].{{Ref/Reuse|NB7}} Through unknown means, Jun eventually escaped Reach, the sole survivor of NOBLE Team.{{Ref/Reuse|universe}} There were several conflicting reports as to how Jun made it safely off-world. One report, designated [[ITEM/466F41.LV]], describes him crossing paths with elements of [[Operation: WHITE GLOVE]], during which time several UNSC personnel were lost in an encounter with a pair of [[Mgalekgolo]] and a squad of [[Special Operations Officer|Special Operations Sangheili]]. However, Covenant artillery and orbital impacts in the area make the details of this report appear suspect. Another account had Jun rendezvous with [[Beta-Red]] for an exfil run. A third report detailing his escape was later noted as being too ridiculous to consider being true.{{Ref/Site|Id=WUIntel|URL=https://www.halowaypoint.com/news/winter-update-intel|Site=Halo Waypoint|Page=Halo Infinite - Winter Update Intel|D=24|M=02|Y=2023|LocalArchive=Halo Infinite Story & Intel}}

===Post-war career===
[[File:Jun SarahPalmer.png|thumb|170px|Jun recruiting Sarah Palmer for the SPARTAN-IV program.]]
{{Quote|Most of them are alright, Musa. And they'll get better. But some of them… some of them are much better.|Jun, while overseeing the training of the first Spartan-IVs{{Ref/Comic|Id=hi2|HInit|Issue=2}}}}
Following the end of the Covenant War, Jun was selected to lead the development of the [[SPARTAN-IV program]], alongside Commander [[Musa-096]]. Technically retiring from active service and becoming a [[civilian]], Jun served as the SPARTAN-IV program's head recruiter.{{Ref/Reuse|universe}} In [[2553|January 2553]], he met with ODST [[Lance Corporal]] [[Sarah Palmer]] aboard [[Lockhart medical station|''Lockhart'' medical station]] and recruited her into the first class of Spartan-IVs.{{Ref/Reuse|hi1}} On [[2553#February|February 15, 2553]],{{Ref/Twitter|Id=bsangel|bsangel|699269947944382464|Jessica Shea|Quote=#TodayInHalo 2/15/2553 E. Buck and V. Dare go on shore leave after the war. Buck is approached by Jun-A266 for integration into SPARTAN-IV.|D=24|M=02|Y=2023}} Jun traveled to the colony of [[Sundown]] in a shuttle to personally offer Edward Buck a place in the first class of Spartan-IVs. Much to Jun's surprise, Buck declined the offer, as he felt that he might have to abandon [[Alpha-Nine|his team]] and his girlfriend, ONI [[Captain (NAVCOM)|Captain]] [[Veronica Dare]]. Buck became the first prospect to decline Jun's offer and the only one to do so within the first class of Spartans.{{Ref/Novel|Id=NB7|HNB|Chapter=7}}

Once several members of the first class were recruited and [[Project ORCHID|augmented]], Jun and Musa's first test for the new recruits was an obstacle course in which Palmer dashed ahead to the objective, leaving her outnumbered comrades behind to be stunned into submission by [[UNSC Marine Corps|UNSC Marines]] participating in the course. Jun and Musa's first lesson to the ambitious recruit was to never seek glory for oneself and stick with one's team. Several days later, Jun and Commander [[Thomas Lasky]] gave the same recruits a tour of the UNSC Navy's experimental [[flagship]] {{UNSCShip|Infinity}}, still undergoing the final stages of its construction within the [[Sol system]]'s [[Oort cloud]]. During the tour, a group of insurrectionists of the [[New Colonial Alliance]] disguised as a construction crew [[Raid on UNSC Infinity|boarded]] ''Infinity'' and took Captain [[Andrew Del Rio]] and ''Infinity''{{'}}s [[bridge]] crew hostage, taking [[Aine|the ship's AI]] offline. The leader of the group, [[Ilsa Zane]], threatened to depressurize the ship and kill everyone aboard if anyone tried to retake the bridge. Though they were not officially authorized to do so, Jun reluctantly allowed the Spartan-IVs to access the [[MJOLNIR Powered Assault Armor (GEN2)|second generation Mjolnir armor]] stored on the ship in order to help the Spartans retake the bridge from the NCA.{{Ref/Reuse|hi2}}

After the Spartan-IVs donned their new armor, Jun explained Zane's background: she was the only survivor of a secret, prototypical phase of the SPARTAN-IV program. Although her physical augmentations are superior to those of the mainline Spartan-IVs, they also made her mentally unstable, resulting in her defection to the NCA. Detecting several Spartans making their way to the bridge of ''Infinity'', Zane depressurized S-Deck, sending several crew members into space with Lasky and Jun being saved by Palmer and Spartan [[Edward Davis]]. While Palmer and Davis made their way to the bridge, Jun and the others engaged NCA forces. Eventually, the Spartans eliminated the rebels and retook ''Infinity''. Afterwards, Musa went before a board of Navy officers and announced the establishment of the Spartans as their [[Spartan Operations|own distinct branch]].{{Ref/Comic|Id=hi3|HInit|Issue=3}}

====Administrating the Spartans====
In [[2554]], the success of the first class of Spartan-IVs allowed Musa to fund further classes and Jun was charged with recruiting more soldiers into the program. Considering his inability to recruit Buck into the first class to be a personal failure, Jun sought him out at [[Leeward's]] bar in [[Karnak]] on the colony of [[Draco III]]. The two shared ''[[Wikipedia:Baijiu|baijiu]]'' together to honor the recently deceased [[rookie]] of Buck's squad. Buck maintained that his answer was the same a year later until Jun informed him that the increased funding in the program allowed for the remainder of Buck's team to become Spartans alongside him. With his largest concerns alleviated, Buck decided to join the program.{{Ref/Novel|Id=NB12|HNB|Chapter=12}} Jun later contacted and recruited [[Kojo Agu]] and [[Michael Crespo]], squad members of Buck's, into the program.{{Ref/Novel|Id=NB14|HNB|Chapter=14}}

As the training of the second class of Spartans had begun, Jun and Musa relocated with them to [[Spartan-IV Training Station|a UNSC space station]] in orbit over a dwarf planet. Shortly after the Spartan-IVs received their augmentations, Jun was informed that one of the trainees, [[Hideo Wakahisa]], did not return from his training exercise. Jun went looking for him and found Wakahisa dead in the tunnels of the training arena furthest from the entrance. While Jun searched the area for evidence, he called in a medical team to remove the body and had the station's administration team search the training recordings to remove most trainees from suspicion. Afterwards, Jun and Musa confronted Buck, Crespo, and Agu in their quarters, as the Spartans were still listed as possible suspects. Jun revealed that he had found a medallion belonging to Crespo, but the latter and his friends insisted that he was not responsible for the murder. Crespo noted that he kept the medallion in his locker—which he never locked—and he believed someone stole it from him. Musa sent Jun to search the security footage of the locker room to find any further leads. Jun was then ordered to assign the three Spartans to temporary quarters and ordered them to remain in the room until further notice.{{Ref/Novel|Id=NB15|HNB|Chapter=15}}

Further investigations soon proved that Spartan trainee [[Rudolf Schein]] was responsible for the murder. Jun, Musa, and Captain [[Marisa O'Day]] went to confront him, but Schein was waiting for them in the station's recreational room and threatened to blow up the entire station unless his demands were met. Musa managed to turn off the station's [[artificial gravity]], which caused the explosives' switches to falter and prevented all the explosives in the station from detonating. Just as Musa shut off the gravity, Jun charged at Schein and knocked the [[grenade]] out of his hand, though the [[Terrorism|terrorist]] still succeeded in detonating the grenade and the resulting explosion killed O'Day and damaged the viewport in the room. As Jun and Schein brawled, they smacked into the viewport and it shattered, pulling them into the vacuum of space. Once Jun w
