Jun-A266

"In recognition of this, his tireless diligence, we honor him as the vigilant eye of Noble."

- The Monument to NOBLE Team

Jun-A266 is a Spartan-III supersoldier and acting Chief of Staff for the Spartan Operations division of the United Nations Space Command. Trained as part of Alpha Company within the SPARTAN-III program, Jun's talent as a marksman and combatant distinguished him from the rest of Alpha Company. After his training, Jun led a Headhunter team, serving in numerous engagements throughout the Human-Covenant War against both human insurrectionist and Covenant forces.

Jun's exceptional skill led to his transfer to Special Warfare Group Three of the UNSC Army, where he served on NOBLE Team with the call sign Noble Three, serving as the fireteam's marksman. However, with the Fall of Reach in summer 2552, Jun became the last survivor of NOBLE Team. With the end of the Covenant War in 2553, Jun had become the head recruiter and a trainer for the Spartan branch and the acting Chief of Staff as of 2558.

Childhood and conscription
"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

Jun was born on February 28, 2524 in the city of Tyumen on the human colony of New Harmony, approximately a year prior to the outbreak of the Human-Covenant War. Through unspecified circumstances, Jun was orphaned at a young age. Under the direction of UNSC Army Colonel James Ackerson, Jun was conscripted into the SPARTAN-III program by December 27, 2532 and brought to Onyx, a world classified by the UNSC Navy's Office of Naval Intelligence. 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 Alpha Company at Camp Currahee. During his training, Jun proved to be an expert marksman and seasoned scout.

In 2536, Jun and the other Spartan-IIIs of Alpha Company underwent physical augmentations aboard, 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.

Early military career
"By my estimation Jun is a rationalist. He is also a Spartan."

- Colonel Urban Holland during his evaluation of Jun-A266's military career

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 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 attacked the Outer Colony of Harvest in 2525. 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, 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.

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. With Jun holding the call sign of "Noble Three", NOBLE Team operated under the command of Colonel Urban Holland, aiding Army teams in operations throughout the Inner Colonies. 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.

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 MST on December 12, the 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 and a number of Wraiths and Ghosts 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 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.

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.

Fumirole
The Battle of Fumirole took place four months after Concord, in April 2552. On April 22, 2552, NOBLE Team was involved in a plan set out by Kat to infiltrate and destroy the 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. 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, where Thom was eventually replaced as "Noble Six" on the team by SPARTAN-B312 months later on July 24, 2552.

Reach
"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

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 discovered Reach. 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.



On 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 local militia. They made their way through several Covenant outposts and discovered a Covenant stealth pylon, to which Jun planted an 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.

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 Long Night of Solace, Jun, in a Falcon, extracted Carter and Kat from the FSS-1000 Sabre 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. Jun participated in the following 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. 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.

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 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 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" artificial intelligence Cortana that carried a "latchkey" discovery found from within the ruins. She ordered NOBLE Team to escort the package to, a that was drydocked at the ship-breaking yards in Asźod preparing to depart from the planet.

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. 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. By the time Spartan-II Red Team arrived at CASTLE the following day, Jun was no longer present at the facility.

At some point just before the fall of the planet, he first encountered Gunnery Sergeant Edward Buck of the 11th Shock Troops Battalion. Through unknown means, Jun eventually escaped Reach, the sole survivor of NOBLE Team. 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 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.

A new class of Spartans
"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

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. In January 2553, he met with ODST Lance Corporal Sarah Palmer aboard Lockhart medical station and recruited her into the first class of Spartan-IVs. On February 15, 2553, 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 his team and his girlfriend, ONI 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.

Once several members of the first class were recruited and 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 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, 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 boarded Infinity and took Captain Andrew Del Rio and Infinity's bridge crew hostage, taking 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 second generation Mjolnir armor stored on the ship in order to help the Spartans retake the bridge from the NCA.

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 own distinct branch.

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 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. Jun later contacted and recruited Kojo Agu and Michael Crespo, squad members of Buck's, into the program.

As the training of the second class of Spartans had begun, Jun and Musa relocated with them to 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.

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 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 was clear of the air escaping the station, he kicked off of Schein's chest and propelled himself back toward the station, leaving the turncoat Spartan-IV to die of vacuum exposure. Lucy-B091 and Tom-B292, who were serving as trainers for the Spartan-IVs aboard the station, witnessed Jun's brawl with Schein from a window and quickly rushed to the older Spartan's aid. Tethered to an airlock, Tom launched himself at Jun in the vacuum and managed to grab hold of him just as Jun lost consciousness, while Lucy used the tether to pull both men back inside the station. The three Spartans were promptly brought to the station's infirmary, and recovered from their exposure to space in several days.

When Spartan Crespo defected to the United Rebel Front while on an operation to Talitsa in 2555, he was eventually detained by Buck and Agu and handed over to Jun, who officially arrested him. By 2556, Jun was still serving as the head recruiter for the branch, having recruited Holly Tanaka into the SPARTAN-IV program upon the recommendations of Captain French of. Jun still held a command position in the Spartan branch as of March 2558, serving as the branch's acting Chief of Staff, a position second only to Rear Admiral Musa who directed the branch. In this capacity, Jun not only cultivated and trained the next generation of Spartans, but directed the operations of all Spartans under the fold of the branch.

Created conflict
In October 2558, when Cortana led an alliance of AIs called the Created to dominate inhabited space, she was joined by Leonidas—the smart AI that assisted Jun in training new trainees aboard the Spartans' space station. When the station was visited by Captain Dare, and Spartans Buck and Agu, Leonidas feigned continued loyalty to the UNSC and insisted that Jun was currently "indisposed", resting after having allegedly stayed awake for several days straight after learning about Cortana's revolution. During the mission to the station, Buck removed and apparently destroyed Leonidas who declared Buck a rogue Spartan. Buck helped Michael Crespo, who was being held on the station, to escape with the unexpected help of Dutch and Gretchen Ketola who were training as Spartans.

As the reunited Alpha-Nine made their escape, they were contacted by Jun who had regained control of the station, having in reality been kept unconscious by Leonidas removing the air from his room until Buck shut the AI down. Jun asked if Buck had removed one of his prisoners and taken care of the AI, causing Buck to become evasive, particularly when Jun pointed out that removing a prisoner from the station without permission was worthy of a court-martial no matter how much good-will Buck may have earned by saving him. Still evading Jun's questions about his actions, Buck warned him that the AI problem was part of a larger network of even greater threats that could even then be quickly approaching the station. Jun assured Buck that they were already undergoing preparations to move to another location. Dropping his more formal demeanor, Jun admitted that he'd contacted Buck to make sure he'd gotten what Buck had come for. Jun understood that desperate times called for desperate measures and warned Buck that Mickey was now his responsibility and thanked Buck for his help, promising not to forget what he did. The two wished each other luck before cutting communication.

Leonidas would later make contact with Cortana, who in turn ordered him to destroy the training station. This act presumably killed most, if not all of the remaining 76 Spartan-IVs and personnel aboard. However, Jun's dialogue with an undisclosed recipient outside of the Spartan branch that happened at unspecified date, in which they discussed the apparent continuation of operations at the Avery J. Johnson Academy of Military Science, suggests that he might have once again survived against the odds.

Personality and traits
"I kill the enemy but do not hate them."

- Jun-A266

Calm and well-practiced, Jun is regarded as "rock solid under pressure" and not arrogant about his exceptional skills as a sniper. Though he is confident in his skills as one of the best marksmen within the entire United Nations Space Command, Jun is reluctant to boast such. Somewhat a loner by nature, Jun competes only with himself and feels as if he has little time for trivial personality conflicts that impede efficiency. Generally unusual for a Spartan, Jun is intriguingly conversational and rather talkative during missions, sometimes to a degree considered against noise discipline protocols within the UNSC. However, this is often overlooked in the field by his peers, due to the informational bent of his chatter. Though Jun is quite vocal and unafraid to speak his mind, he is always tightly focused on the mission at hand. Some have mistaken this character trait for a deep philosophy, but in truth, it is more pragmatic than mystical. Jun is known for remaining unwaveringly composed, even under the highest of pressures. However, Jun is not one to show mercy to his opponents; Musa-096 believed he would assuredly have killed a former ally who betrayed him and defected from the UNSC.

During his service on NOBLE Team, he formed bonds with several of his teammates, particularly Jorge-052. In turn, Jun witnessed the death of many teammates and, by the end of the Fall of Reach, Jun was the fireteam's only survivor. While he appeared regretful of their deaths, he did not seem to show any emotion when speaking of them. As a Spartan-III who served throughout much of the Human-Covenant War, Jun had become accustomed with loss and witnessed some of the best and brightest of humanity's youth be sacrificed—sometimes pointlessly—for temporary gain in the war. With the Covenant War's end, Jun was selected to lead the development of the SPARTAN-IV program, alongside Musa-096. While the SPARTAN-II and SPARTAN-III programs illegally conscripted children to serve as supersoldiers, the Spartan-IVs would be selective, consenting adults, which Jun considered an excellent side effect. Jun views the Spartan-IVs and Spartan Operations itself as a necessary compromise between the creation of child soldiers and the need for supersoldiers in an extremely dangerous galaxy. While serving as the head recruiter for the SPARTAN-IV program, Jun conducts himself professionally and portrays himself as perpetually somber. Jun takes his duties as head recruiter and training overseer with deadly seriousness, and is uncompromising in his review process of potential Spartan inductees. Though Jun personally recruited Spartans into the program that have eventually gone rogue or failed the training process, to outsiders he often seems unconcerned. However, only Musa is aware that Jun secretly takes even those events as evidence of the success of the SPARTAN-IV program, as those men and women had a choice as to what they would eventually become.

Jun has shown symptoms of post-traumatic stress in the past and had underwent therapy to counter it; by 2550, Jun has shown no indications of a relapse post-therapy. In a mandatory psychiatric evaluation on December 15, 2549, Jun was noted as having "an unhealthy emotional detachment in regards to the consequences of his actions". Colonel Urban Holland, who later evaluated the members of Noble Team, disagreed with this assertion, commenting that Jun is both a rationalist and a Spartan. Jun rarely speaks of his service as a Headhunter early in his career.

Physical description
By 2552, Jun stood at 210.5 centimeters (6 feet and 10.9 inches) and weighed 111.1 kilograms (245 pounds). He has a shaved head and blue eyes, with brown eyebrows. He has a tattoo of a fist clutching three arrows on the left side of his face. Edward Buck noted that Jun carried himself with a quiet power that reminded you that he could "kill everyone within sight in a matter of seconds".

Skills and abilities
"Jun, Noble Three. As a sniper, his skills are unmatched."

- Doctor Catherine Halsey, speaking of Jun's skills during his time on NOBLE Team

An expert marksman and a seasoned warrior, Jun is widely recognized across the United Nations Space Command as one of the most talented snipers alive. Although he has since retired from active service and rarely has the opportunity to use his skills in the field, Jun remains a deadly combatant who is more than capable of holding his own, even alongside MJOLNIR-clad Spartan-IVs. As a child conscripted into Alpha Company of the SPARTAN-III program, Jun quickly proved himself to be a skilled marksman and seasoned scout. Following his augmentations, Jun became one of Alpha Company's greatest assets, as his skill as a sniper led him to carry out operations directly under the authority of the Office of Naval Intelligence. Jun's primary Military Occupational Specialty is listed as 180B.

Talented with long-range combat, Jun is considered to be one of the recognized masters of the SRS99-AM sniper rifle within the UNSC. With the dedicated skill he brings to the task of serving as a fireteam's marksman, Jun is able to remain still for incredibly long periods of time. Even as a civilian, Jun does not hold back from combat when the need to fight a threat arises. When was boarded by the New Colonial Alliance in 2553, Jun aided in combating the insurrectionists and retaking the ship, despite being unarmored. Later in 2554, when Spartan-IV trainee Rudolf Schein defected to the United Rebel Front and attempted to take an entire space station hostage while donning an explosive bandoleer, Jun charged at the Spartan and successfully engaged him in hand-to-hand combat. The two were eventually knocked into the vacuum of space, though Jun managed to use Schein to propel himself back toward the station, enabling him to be rescued in time; Musa-096 later commented that Jun—as a Spartan-III—was built to last.

Aside from his combat skills, Jun's ability to maintain situational awareness and predict enemy behavior is particularly notable, as is his attention to detail while he conducted overwatch operations. Even after retired and becoming a civilian, Jun's perceptiveness and ability to discern motivations from seemingly casual contact is considered almost preternatural. Jun often downplays this ability, describing it as a combination of simple deduction and great skill at being able to lip-read, or mandible-read, in the case of Sangheili.

Equipment
"High velocity, armor-piercing. They'll take the hat off an Elite at two thousand yards. And they ain't cheap."

- Jun-A266, referring to his 14.5×114mm ammunition

Jun's Mjolnir Mark V armor was configured to suit his role as a sniper. He wore a Scout helmet with an HU/RS upgrade with an brownish orange-colored visor, a Tactical/Patrol chest piece with a rucksack for additional storage, and FJ/PARA knee guards. He wore his combat knife and spare 14.5×114mm sniper rifle rounds on his right and left shoulders respectively. His left forearm was equipped with a Tactical/UGPS unit. With the dawn of the GEN2 platform of Mjolnir armor, Jun requested a one-off upgrade to his armor. Interest in the suit's feature set among Spartan scout-snipers led to several other sets based on this design, and it being termed VIGILANT-class Mjolnir. Jun also wore elements of a custom ghillie suit that allowed him to blend into surrounding foliage to remain hidden from hostiles while he served as a marksman. As a civilian and the head recruiter for the SPARTAN-IV program, Jun dressed in black business attire.

As a sniper for NOBLE Team, Jun's weapon of choice was the SRS99-AM sniper rifle, with an M6G magnum for a sidearm. Though he also armed himself with an M392 designated marksman rifle and an MA37 assault rifle in certain situations. He was also equipped with a standard-issue combat knife. As a sniper, Jun utilized 14.5×114mm rounds for his rifle.

Halo: Reach
Jun can be unlocked as a custom voice for use in the Firefight component of Halo: Reach multiplayer. In Halo: The Master Chief Collection, he can be unlocked as part of the Series 1: Noble progression track. Jun's helmet was additionally made available as an avatar award on the Xbox 360, unlocked by killing 100 enemies in a row without dying in campaign or Firefight.

Halo Infinite
A Jun-themed armour kit is available for unlock as part of Season 01: Heroes of Reach, in Halo Infinite multiplayer.

Production notes
In Halo: Reach, Jun was voiced by American actor Sunil Malhotra. Jun serves as a supporting character in Halo: Reach, though his voice can be used in the game's Firefight mode for 10,000 credits.

Jun becoming a recruiter for the SPARTAN-IV program was first teased in the Xbox Live Marketplace's description for the Commander Palmer Armor avatar, in July 2013. Prior to the release of Halo: Initiation in August 2013, which confirmed and expanded on this information, there existed numerous discussions involving Jun's fate following the events of Halo: Reach. As Jun is not mentioned in Halo: First Strike, fans long speculated that he was killed between the events of "The Package" and the novel. In the Halo: Reach Legendary Edition developer commentary, Martin O'Donnell and Lee Wilson jokingly state that "the sequel" tells the story of Jun and Halsey's escape, and of their children, who are "very smart snipers". At Comic-Con 2011, Frank O'Connor stated, "Jun's fate may not ever be discovered." During Halo Waypoint's exploration and background explanation on the Defiant Map Pack, three dead Spartans wearing armor identical to Jun can be seen in the remains of a destroyed Pelican on the level Highlands.

Jun is the protagonist of the fan-made graphic novel Halo: A Fistful of Arrows, written and drawn by Levi "Leviathan" Hoffmeier, which is named in reference to Jun's tattoo. In a conversation between Bungie employee Martin O'Donnell and Hoffmeier on the halo.bungie.org forums, O'Donnell joked that "[...] Jun tripped and broke his neck on the way to escorting Halsey off Reach [and] he's dead." Hoffmeier then drew a short comic strip depicting the event. 343 Industries later referenced A Fistful of Arrows in a Q&A session in their Canon Fodder blog, stating that "the details of [Jun's] survival and escape from Reach remain buried under fistfuls of black ink and red tape." A Fistful of Arrows was again referenced in the Winter Update intel drops for Halo Infinite in the file "ITEM/466F41.LV", with the "LV" being a nod to the comic's creator, Leviathan. The file references the events of the comic, though is dismissed with the relevant details being "debatable at best", with a number of other reports existing in-universe to contract this story and suggest that the true events of Jun's escape from Reach are a mystery even in-setting.

One such conflicting report mentioned in the Intel drops mentions Jun linking up with Beta-Red from the Reach radio conversations, while another is dismissed outright as simply too outrageous to ever consider seriously. This last entry may be a nod to a non-canon short story written by Frank O'Connor in a Twitter thread posted in late 2018. The thread (whose full transcript is copied below) depicts Jun as climbing a large space elevator (or similarly-large structure) on Reach to reach a communications pod and call for evacuation.
