Editing Fireteam Crimson

'''Fireteam Crimson''' is a team of [[SPARTAN-IV program|Spartan-IV supersoldiers]]. Crimson was assigned to {{UNSCShip|Infinity}} during the ship's [[Requiem Campaign|second expedition]] to the [[Forerunner]] [[shield world]] [[Requiem]] in [[2558#Februrary|February 2558]]. Operating on Requiem, Crimson is frequently assigned on ground missions in which they combat the shield world's resident [[Promethean]] constructs and [[Jul 'Mdama]]'s [[Jul 'Mdama's Covenant|Covenant]] forces.<ref name="Joystiq 5162012">[http://www.joystiq.com/2012/05/16/halo-4s-infinity-multiplayer-to-introduce-spartan-ops-war-ga/ '''Joystiq''': ''Halo 4's 'Infinity' multiplayer to introduce Spartan Ops, War Games'']</ref>

At some point Fireteam Crimson had the following team configuration:<ref name="Mega">[http://www.toywiz.com/megabloks97349.html '''Toywiz''': ''UNSC Fireteam Crimson Set Mega Bloks 97349 Halo'']</ref>

===Eklund is transferred out===

By [[2554]], Fireteam Crimson participated in operations [[Operation: BELLINGHAM|BELLINGHAM]] and [[Operation: LATE TAXI|LATE TAXI]], with both being successful. In both operations, Spartan [[Sigrid Eklund]]'s skills were noted by [[Jun-A266]], who would recommend Eklund for more isolated endeavors. [[Musa Ghanem]] would approve this transfer request, pulling Eklund out of Crimson.{{Ref/Site|Id=S2StoryHub|URL=https://www.halowaypoint.com/halo-infinite|Site=Halo Waypoint|Page=Halo Infinite|Detail=Season 02 Lone Wolves - Story & Intel|D=19|M=07|Y=2022}}

On February 9th, [[2558]], Crimson, alongside [[Fireteam Majestic]] were assigned by [[Sarah Palmer|Commander Palmer]] to eliminate [[Jul 'Mdama's Covenant|Covenant cultists]] at two identical structures in order to establish a base at [[REQ-626-C]] as part of a prelude to the [[Requiem Campaign|UNSC's campaign on Requiem]]. Crimson was to clear out a structure known as [[Fortress (location)|REQ-814-B]] while Majestic cleared out [[REQ-814-D]]. Despite facing more enemies, Crimson was able to clear out their structure before Majestic.{{Ref/Game|Id=IFB|Halo 4 Limited Edition|[[Infinity Briefing Packet|''Infinity'' briefing packet]]}}

Crimson was deployed in a joint [[UNSC]] [[UNSCDF|military]] [[Operation|operation]] on [[Requiem]] alongside [[Fireteam]]s [[Castle Squad|Castle]], [[Fireteam Domino|Domino]], [[Fireteam Ivy|Ivy]], and Majestic. [[SPARTAN-IV Program|Spartan]] [[Jared Miller]] was personally assigned to Crimson as their mission handler. Crimson was dropped behind-enemy-lines to assist [[UNSC Marines|Marines]] in neutralizing [[Jul 'Mdama's Covenant|Covenant forces]] in the area. In an attempt to stop Jul 'Mdama's Covenant from establishing permanent bases throughout Requiem, Crimson was also given the objective to destroy four power cores acting as short-range wireless transceivers, and was successful. After mopping up whatever Covenant forces were left in the area, Miller sent a [[D79-TC Pelican|Pelican]] dropship for extraction. [[Commander]] [[Sarah Palmer]] congratulated them on their mission success.<ref>''Spartan Ops'', [[Departure/Land Grab|S101 Land Grab]]</ref>

Subsequently Crimson was sent to capture a Covenant-held power station on [[Requiem]] in "[[Sniper Alley]]." They were tasked with eliminating all Covenant forces within the area. Miller concluded that 'Mdama's Covenant were siphoning large amounts of energy from a nearby [[Forerunner]] structure. [[SPARTAN-IV Program|Spartan]] [[Robert Dalton]] came online and readied an orbital-strike from the ''Infinity'' to destroy the target energy source. The target was destroyed by ''Infinity'', and Fireteam Crimson was extracted from the area.<ref>''Spartan Ops'', [[Departure/Sniper Alley|S101 Sniper Alley]]</ref> Crimson and Majestic were sent north of the UNSC's area of operations in Requiem in order to shut down [[Forerunner]] power generators at the "[[Fortress (location)|Fortress]]." Both teams were sent to their individual locations to complete their objectives. Upon insertion, both Crimson and Majestic had their long-range communications jammed, but deactivated the jammers. The area was quickly swarmed with [[Promethean Crawler]]s and [[Promethean Watcher]]s as Crimson fought to disable the arrays powering the Forerunner structure. Initiated by Palmer, the mission turned into a competition where both fireteams were trying to complete their mission objectives first. Majestic temporarily took the lead, but Crimson eventually beat Majestic. Dalton arrived in a Pelican dropship for Crimson's extraction.<ref>''Spartan Ops'', [[Departure/The Challenge|S101 The Challenge]]</ref>

Next Crimson was sent to "[[The Refuge (Requiem location)|the Refuge]]," a jungle Forerunner structure that scientists were preparing to set up shop in. They were attacked by more [[Promethean]] forces and activated a star chart. Miller processed the data and Palmer tried to get them extracted. The door locked, shutting Crimson in the facility, and [[Promethean Knight]]s arrived in the area. Crimson beat off the foes while Miller opened the door allowing Crimson to escape on Dalton's Pelican.<ref>''Spartan Ops'', [[Departure/Sacred|S101 Sacred]]</ref> Crimson was then sent into a Covenant dig site at "[[the Cauldron]]," a Forerunner area. 'Mdama's Covenant resistance was strong, leading Palmer to wonder what they were guarding. Crimson fought their way to a [[Requiem slipspace artifacts|mysterious artifact]] guarded by Promethean Knights. After fighting them off, Crimson recovered the Artifact, boarded the Pelican, and brought it back on ''Infinity''.<ref>''Spartan Ops'', [[Departure/Core|S101 Core]]</ref>

Later Crimson was sent in to "[[the Gate]]," a location that the Marines had failed to take from Jul 'Mdama's Covenant. After fighting through [[Kig-Yar]] and [[Unggoy]] they faced Promethean resistance. The incoming Prometheans were dispatched by Crimson, and Miller tasked the team with disabling pylons controlling Forerunner turrets. Dalton came in and evacuated Crimson after they faced more translocating Knights and Crawlers. They were sent to respond to a science team's distress call.<ref>''Spartan Ops'', [[Artifact (Spartan Ops)/Clean Up|S102 Clean Up]]</ref> The aforementioned science team hid behind a forcefield when 'Mdama's Covenant attacked, and were the science team assigned to the Cauldron. Crimson destroyed Covenant communications arrays, and found beacons and IFF tags from the science team. Dr. [[Morgan Rivera]] was brought on comms who gave Crimson her location. Crimson fought through 'Mdama's Covenant and rescued her and her team.<ref>''Spartan Ops'', [[Artifact (Spartan Ops)/For Science|S102 For Science]]</ref>

Next Crimson was sent in to evacuate Marine squad Hacksaw who was attacked by Covenant at the Fortress. They were dropped in and beat back waves of Covenant forces to rescue the Marines. The group moved to the top of the Fortress to be evacuated by Dalton, but [[Ru'swum-pattern Phantom|Phantoms]] arrived carrying [[Sangheili Warrior]]s and [[Sangheili Zealot]]s. Crimson destroyed the Phantoms and Sangheili and were evacuated.<ref>''Spartan Ops'', [[Artifact (Spartan Ops)/Hacksaw|S102 Hacksaw]]</ref> En route to "the Refuge," Crimson was shot down in "Sniper Alley" by nearby anti-air turrets and were thought to have died. Miller learned that Fireteam Crimson was still alive and they were sent to take out the turrets. Covenant forces arrived supplanted by [[Heavy orbital insertion pod]]s, but Crimson eliminated 'Mdama's Covenant forces and the turrets and continued with their mission.<ref>''Spartan Ops'', [[Artifact (Spartan Ops)/Pelican Down|S102 Pelican Down]]</ref> Reaching "the Refuge," Crimson saw no sign of Gagarin team, the science team based there. They learned Gagarin activated Forerunner artifacts, and Crimson deactivated them under resistance from Promethean forces. They got on a Pelican and left, not having found Gagarin team.<ref>''Spartan Ops'', [[Artifact (Spartan Ops)/Gagarin|S102 Gagarin]]</ref>

Commander Palmer deployed Crimson team to a rocky area of Requiem to hunt for [[Parg Vol]], a Sangheili terrorist and associate of [[Jul 'Mdama]]. After facing heavy Covenant resistance, they were unable to kill Vol and he escaped.<ref>''Spartan Ops'', [[Catherine/The VIP|S103 The VIP]]</ref> Crimson was then sent to [[Galileo Base]], a science facility on Requiem under heavy attack by Covenant forces. They managed to beat back Jul 'Mdama's Covenant and drive them away from Galileo Base.<ref>''Spartan Ops'', [[Catherine/Galileo|S103 Galileo]]</ref> Next Crimson arrived at [[Two Giants]], a canyon with two [[beam emitter]]s, to assist Spartan squad Mountain. Beating off Covenant forces Crimson retrieved the marines and activated Forerunner technology in the towers.<ref>''Spartan Ops'', [[Catherine/Spartan Mountain|S103 Spartan Mountain]]</ref> 'Mdama's Covenant responded by sending an entire fleet of foes from a {{Pattern|Zanar|light cruiser}}. Palmer dropped in several [[HRUNTING/YGGDRASIL Mark IX Armor Defense System|Mantis]] mech suits which Crimson used to beat back the fleet while the cruiser was destroyed by ''[[Infinity Sub-Vessel 3]]''.<ref>''Spartan Ops'', [[Catherine/Shootout In Valhalla|S103 Shootout in Valhalla]]</ref> Vol was once again located, this time re-taking "the Gate" location with his Covenant forces. Crimson [[Assassination of Parg Vol|neutralized him]] and several Covenant and Promethean warriors.<ref>''Spartan Ops'', [[Catherine/Hunting Trip|S103 Hunting Trip]]</ref>

Soon after, Crimson was then sent to disable a Covenant communications array at the site Jul 'Mama's Covenant had previously had anti-air turrets. The array had led to the death of [[Fireteam Castle]], and Crimson rushed the location and tapped into the array before disabling it.<ref>''Spartan Ops'', [[Didact's Hand/Hairy Call|S104 Hairy Call]]</ref> ''UNSC Infinity'' found data possibly leading to Jul 'Mdama's location. The data placed 'Mdama at the "[[Two Giants]]" where a tower had been retaken by Covenant forces. Activating Forerunner technology, a portal opened and Crimson stepped through.<ref>''Spartan Ops'', [[Didact's Hand/Rally Point|S104 Rally Point]]</ref> They emerged in "the [[Fortress (location)|Fortress]]" and re-established communications primarily with the AI [[Roland]]. After fighting off enemy forces Crimson steped through another portal, chasing 'Mdama.<ref>''Spartan Ops'', [[Didact's Hand/Random Transport|S104 Random Transport]]</ref> Crimson emerged in the middle of Covenant enemies at "[[the Cauldron]]", and fought through them to reach 'Mdama. ''Infinity'' bombed 'Mdama's location causing him to drop the [[Didact's Gift]], which was recovered by the UNSC and subsequently brought to Galileo Base.<ref>''Spartan Ops'', [[Didact's Hand/The Chase|S104 The Chase]]</ref> However, 'Mdama's Covenant [[Battle of Galileo Base|attacked]] Galileo Base with the intent of recovering the gift. Crimson beat them back and activated the base's defense systems, holding back 'Mdama's Covenant but Prometheans translocated in the base. Crimson fought them off and left [[Fireteam Majestic]] to take the Didact's Gift to ''Infinity''.<ref>''Spartan Ops'', [[Didact's Hand/The Didact's Gift|S104 The Didact's Gift]]</ref>

On Crimson's next deployment, they were sent to "[[the Gate]]" to investigate Dr. [[Leslie Boyd]]'s power fluctuations back at "[[the Refuge (Requiem location)|the Refuge]]" with only Roland and Miller to help them. They were being caused by translocating Prometheans, and they were at risk of destroying Boyd's scientific instruments. They defended them from raids of Prometheans until Boyd could finish his work and block their translocations. Boyd opened a portal for Crimson, now able to control the portal's locations.<ref>''Spartan Ops'', [[Memento Mori/Spartan Miller|S105 Spartan Miller]]</ref> At "the Refuge," the science base came [[Battle at The Refuge|under attack]] by Prometheans, which were driven off by Crimson.<ref>''Spartan Ops'', [[Memento Mori/Nothing Can Go Wrong|S105 Nothing Can Go Wrong]]</ref> A {{Pattern|Zanar|light cruiser}} began sending a Covenant army down to "the Refuge," and Crimson defended the location while [[Fireteam Shadow]] took out the cruiser. Successfully defending Dr. Boyd, Crimson team left on a Pelican to their next objective.<ref>''Spartan Ops'', [[Memento Mori/Everything Has Gone Wrong|S105 Everything Has Gone Wrong]]</ref> Crimson arrived at [[Magma Base]] to defend power generators from Covenant forces. After doing so, Roland found [[Gabriel Thorne]]'s IFF tag in the area, and found it along with signs of a struggle.<ref>''Spartan Ops'', [[Memento Mori/The Cauldron Base|S105 The Cauldron Base]]</ref> Crimson was dropped off in the "[[Quarry]]" to try and find Thorne. Despite defeating a large amount of Covenant, Thorne was not found. A Pelican arrived for evac but was destroyed by Jul 'Mdama's Covenant. [[Ru'swum-pattern Phantom|Phantoms]] and [[Type-26 Banshee|Banshees]] then converged on Crimson's position, along with a single light cruiser.<ref>''Spartan Ops'', [[Memento Mori/Spartan Thorne|S105 Spartan Thorne]]</ref>

Fireteam Crimson was eventually [[Ambush at the Quarry|captured]] and brought to a Covenant detention facility. After Roland located Crimson, Miller ordered a diversionary bombardment by Dalton.  The resulting explosion distracted the guards, which allowed Crimson to [[Escape from Lockup|escape]]. Crimson then neutralized the remaining guards and fended off waves of reinforcements as they attempted to escape. They deactivated a shield door and engaged more Covenant including [[Type-55 Shade|Shade turrets]]. Miller decided Crimson must hijack a Phantom to escape, however after entering the next area a Marine squad known as [[Icebreaker squad|Icebreaker]] was detected. Crimson engaged the guards, which included Promethean Crawlers. After freeing the Marines, one of them, Lieutenant [[TJ Murphy]], said he could remotely take over a nearby Phantom. Crimson covered him while he did so, holding off several waves of Covenant troops. Eventually Lieutenant Murphy was able to take over the Phantom, allowing Crimson and the surviving Marines to escape.<ref>''Spartan Ops'', [[Scattered/Escape Plan|S106 Escape Plan]]</ref>

Fireteam Crimson used their captured Phantom to great use. They first infiltrated a secure Covenant facility and retrieved vital intelligence from the computers there.<ref>''Spartan Ops'', [[Scattered/All The Secrets|S106 All The Secrets]]</ref> This led them to a central intel facility based in the "[[Warrens]]." Crimson attacked the facility and gained access to a Covenant computer, which revealed the locations of a Covenant archaeological dig and a plasma supply depot. Crimson was sent to destroy the supply depot while Fireteam Switchback was sent to stop the dig.<ref>''Spartan Ops'', [[Scattered/Need To Know|S106 Need To Know]]</ref>

Crimson successfully infiltrated the supply depot at "[[Cyclone]]" and destroyed the plasma stockpiles. However, they also discovered that Jul 'Mdama's Covenant had stolen a large amount of UNSC weaponry - including nuclear weapons. The warheads themselves could not be found. They then received a distress call from Switchback, who were at the dig site.<ref>''Spartan Ops'', [[Scattered/Search and Destroy|S106 Search and Destroy]]</ref> Crimson headed over to [[Harvester (location)|the dig site]] to help Switchback, but discovered no trace of the team except for their IFF tags. On Commander Palmer's orders, Crimson attacked and disabled [[Za'zayara-pattern Harvester|the Harvester]] 'Mdama's Covenant were using in their dig.<ref>''Spartan Ops'', [[Scattered/Switchback|S106 Swichback]]</ref>

Later, when the ''Infinity'' [[Invasion of the UNSC Infinity|came under attack]] by Covenant and Promethean forces, Crimson was recalled to help defend the ship. Because Crimson was already engaged in an operation at [[Apex]] when the ''Infinity'' was attacked, Crimson had to clear the area of enemy forces in order to let Murphy pick them up. Murphy assisted by delivering Crimson a Mantis, which greatly aided in clearing out Apex. Murphy then picked Crimson up in his Phantom and took them back to ''Infinity''.<ref>''Spartan Ops'', [[Invasion (Spartan Ops)/Backup|S107 Backup]]</ref>

On their way back to ''Infinity'', Crimson's stolen Phantom was damaged by the ship's own automated defenses. They crashed into a hangar bay, but survived. After clearing out the initial Covenant boarders inside the hangar, Crimson tried to seal the hangar doors to block off further intrusions in that area. However, the door controls malfunctioned due to the effects of the artifact. Roland instructed Crimson to head to the server room and power cycle the systems there. Crimson did so, and restored hangar controls. They then fought their way back to the hangar and closed the doors again.<ref>''Spartan Ops'', [[Invasion (Spartan Ops)/Home Field|S107 Home Field]]</ref>

Crimson then had to face another crisis: Jul 'Mdama's Covenant had broken into the engine room and were planning to destroy the ship with the stolen [[HAVOK tactical nuclear weapon]]s. After a quick detour to the server room - where they stopped 'Mdama's Covenant from detonating one of their HAVOKs - Crimson entered the engine room. They cleared out the initial Covenant intruders and disarmed all of the warheads.<ref>''Spartan Ops'', [[Invasion (Spartan Ops)/Engine of Destruction|S107 Engine of Destruction]]</ref> A new wave of Covenant soon attacked the engine room, but Crimson successfully repelled them. They then sealed off the engine room by closing the emergency bulkhead doors.<ref name="Guns">''Spartan Ops'', [[Invasion (Spartan Ops)/The Guns of Infinity|S107 The Guns of ''Infinity'']]</ref>

At that point, Jul 'Mdama's Covenant disabled ''Infinity's'' aft weapons.  On Miller's orders, Crimson headed over to aft weapons control, where they destroyed 'Mdama's Covenant hardware jamming devices preventing the guns from firing. They then brought the ship's weapons back online, destroying at least one of the {{Pattern|Zanar|light cruiser}}s attacking the ship.{{Ref/Reuse|Guns}} Crimson was then ordered to retake the server room, which had again been invaded by enemy forces. They secured the server room for a third and final time, then returned to the hangar bay.  There, they battled and defeated a large force of Hunters. By now, the tide had turned in the UNSC's favor.<ref>''Spartan Ops'', [[Invasion (Spartan Ops)/Victory Lap|S107 Victory Lap]]</ref>

After ''Infinity'' was secured, Crimson was redeployed to Requiem, where they performed a number of operations. They first retook "[[Apex]]" from Jul 'Mdama's Covenant and shut down several portals.<ref>''Spartan Ops'', [[Expendable/Unfinished Business|S108 Unfinished Business]]</ref> They then destroyed Covenant artillery batteries besieging Fireteam Majestic.<ref>''Spartan Ops'', [[Expendable/Majestic Rescue|S108 Majestic Rescue]]</ref> They then aided Fireteam Lancer in destroying a Covenant base hidden in the "[[Warrens]]". During this mission, they found and rescued the survivors of Fireteam Switchback. During these operations, Miller noted that 'Mdama's Covenant seemed to be able to predict their moves.<ref>''Spartan Ops'', [[Expendable/Lancer|S108 Lancer]]</ref> After Miller and Palmer learned about a Covenant listening post from a captured Elite, Crimson was sent to the outpost to investigate.  There, they discovered a captured UNSC Pelican being used to listen in on the UNSC's communications.  Crimson cleared 'Mdama's Covenant defenders and ''Infinity'' launched an aerial bombardment that destroyed the Pelican.<ref>''Spartan Ops'', [[Expendable/Crystal Ball|S108 Crystal Ball]]</ref>

Dr. Glassman then requested Crimson's aid in deciphering a holographic map of Requiem. To this end, Crimson attacked a Covenant base located at a specific Forerunner structure. Glassman was able to use the map to guide Crimson in activating the structure's automated defense systems, which easily destroyed Covenant reinforcements.<ref>''Spartan Ops'', [[Expendable/Glassman|S108 Glassman]]</ref>

After Doctor [[Catherine Halsey]]'s abduction by Covenant forces, all Spartan fireteams were dispatched to find her.  Fireteam Crimson was first sent to a location in "[[Cyclone]]" where they investigated a transmission seemingly sent by Halsey. After clearing out Jul 'Mdama's Covenant forces guarding the base, they delved deeper into the structure and found a Covenant comm terminal with a message from Jul 'Mdama, ordering all forces to head to Librarian's Rest. While investigating, Crimson came under attack by Prometheans. The Spartans were unexpectedly aided by Sentinels under the control of the [[Librarian]] who they aided in transmitting herself to [[the Absolute Record]].<ref>''Spartan Ops'', [[Key/The Search for Halsey|S109 The Search for Halsey]]</ref> Roland eventually traced Halsey's transmission to another Covenant-occupied Forerunner structure at "[[Control]]." Upon investigating, Crimson learned the transmission had been sent to "[[Lockup]]."<ref>''Spartan Ops'', [[Key/Clean Up|S109 Clean Up]]</ref> Crimson then investigated another transmission sent by Halsey through Apex this time. Using Scorpion tanks, the Spartans fought their way through Covenant and Promethean forces and reached the terminal where Halsey's transmission had been sent to. This transmission had also been relayed to "Lockup."<ref>''Spartan Ops'', [[Key/Science Mountain|S109 Science Mountain]]</ref>

Upon being deployed at "Lockup," Crimson stormed the facility and defeated 'Mdama's Covenant guards.<ref>''Spartan Ops'', [[Key/Revenge|S109 Revenge]]</ref> However, Covenant and Promethean reinforcements soon showed up, forcing them not only to fend for themselves, but also assist the Marine squad that had accompanied them. After repelling the attackers, Crimson found a grav lift that led them to the top of the structure. There they discovered that 'Mdama's Covenant had previously (and unsuccessfully) tried to force a captured Marine squad to activate a Forerunner device. Crimson defeated a final counterattack by Covenant forces, then activated the device themselves.<ref name="The Hammer">''Spartan Ops'', [[Key/The Hammer|S109 The Hammer]]</ref> The device revealed holographic map of Requiem similar to the one [[Fireteam Majestic]] had found on [[Gek 'Lhar]] earlier.<ref name="Expendable">''Spartan Ops'', [[Expendable|S108 Expendable]]</ref> Roland determined they could use this map to find a way to free ''Infinity'' from Requiem.{{Ref/Reuse|The Hammer}}

During the final phase of the [[Requiem Campaign]], Fireteam Crimson was dispatched to locate and disable one of two [[Requiem slipspace artifacts|Forerunner artifacts]] on Requiem that were binding ''Infinity'' to Requiem. Their task was made all the more urgent when Jul 'Mdama sent Requiem on a course with the sun.<ref name="Exodus">''Spartan Ops'', [[Exodus (Spartan Ops)|S1010 Exodus]]</ref>

Following the coordinates Dr. Glassman had derived from the map, Crimson returned to the dig site. There they discovered that Jul 'Mdama's Covenant itself had been after the artifact, which was buried deep within the mountain. Miller ordered them to recapture the [[Za'zayara-pattern Harvester|Harvester]] they'd previously disabled, and use its [[plasma drill]] to breach the rocks. The Harvester was shielded and air support was needed to disable it. After Crimson destroyed three Forerunner anti-aircraft guns guarding the area, Murphy arrived in a Pelican and disabled the Harvester's shield.  Crimson then boarded the Harvester and eliminated 'Mdama's Covenant crew. They also rescued some captured scientists who 'Mdama's Covenant were forcing to fix the Harvester. Unfortunately, the Harvester's power supply had been destroyed by Crimson during their previous raid. Roland came up with a plan to find a new power source located at "[[Apex]]."<ref>''Spartan Ops'', [[Exodus (Spartan Ops)/Artifact|S1010 Artifact]]</ref>

[[File:Crimson and Majestic Pelicans.jpg|thumb|right|250px|Crimson's and Majestic's Pelicans escaping from Requiem.]]

Due to heavy enemy activity at "Apex," Crimson was unable to go there directly. Instead, they landed at the "[[Warrens]]" and took a back route to Apex through a Covenant base.<ref>''Spartan Ops'', [[Exodus (Spartan Ops)/In One Way|S1010 In One Way]]</ref> Once at "Apex," Crimson joined forces with [[Fireteam Forest]], a Spartan Fireteam that had been trapped on Apex earlier. Crimson and Forest fought their way to a Covenant communications terminal, and, on Roland's orders, activated it.  This summoned a [[Kmiro'sish-pattern Lich|Lich]] to the scene. Roland explained his plan for Crimson to board the Lich and steal its power core. Despite the numerous waves of troops the Lich sent at them, Crimson boarded the ship, eliminated its crew, and stole the engine core.<ref>''Spartan Ops'', [[Exodus (Spartan Ops)/Seize the Power|S1010 Seize the Power]]</ref> They then returned to the "Warrens," where they disabled the power source for the Forerunner AA guns in the area. They then used a salvaged [[Mantis]] to fight their way back outside, where they were picked up by a Pelican.<ref>''Spartan Ops'', [[Exodus (Spartan Ops)/Out the Other|S1010 Out the Other]]</ref>

Crimson recaptured the Harvester and powered it back up using the Lich's engine core. They used the Harvester's plasma drill to carve out an entrance in the rocks, exposing a cave.  Crimson entered the cave and fought their way through numerous Prometheans before finally reaching the artifact, which was housed within a massive Forerunner structure. They deactivated the artifact and escaped as the cavern began to collapse. Near the exit, Crimson encountered one last group of Sangheili. After defeating the Elites, Crimson exited the cave and made it back outside, where Murphy arrived in a Pelican to pick them up.<ref>''Spartan Ops'', [[Exodus (Spartan Ops)/One Last Time|S1010 One Last Time]]</ref>

*Fireteam Crimson are the playable protagonists of ''[[Halo 4]]''<nowiki>'</nowiki>s ''[[Spartan Ops]]'' cooperative campaign. Like [[SPARTAN-B312|Noble Six]] in ''[[Halo: Reach]]'', their appearance, gender, and equipment are determined by the players. Even the size of the team is not established in the game, as ''Spartan Ops'' supports between one and four players per chapter. Presumably Crimson has four members, though, as that is the recommended team composition for ''Spartan Ops'' sessions (as well as the default team size in [[matchmaking]]). Nonetheless, dialog and the ''Fireteam'' designation clearly indicate that Crimson canonically has multiple members.
