Fireteam Crimson

"I need a fireteam I can depend on and, until you prove otherwise, you’re it."

- Sarah Palmer

Fireteam Crimson is a team of SPARTAN-IV supersoldiers. Crimson was assigned to the during the ship's second expedition to the Forerunner shield world Requiem in February 2558. Operating on Requiem, Crimson is frequently assigned on ground missions in which they combat the shield world's resident Promethean constructs and the Covenant remnant.

In 2558 Crimson was deployed in a joint UNSC military operation on Requiem alongside Fireteams Castle, Majestic, Domino, and Ivy. Spartan Jared Miller was personally assigned to Crimson as their mission handler. Crimson was dropped behind-enemy-lines to assist marines in neutralizing Covenant forces in the area. In an attempt to stop the 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 Pelican dropship for extraction. Commander Sarah Palmer congratulated them on their mission success.

Fireteam Crimson was sent to capture a Covenant-held power station on Requiem, Sniper Alley. They were tasked with eliminating all Covenant forces within the area. Miller concluded that the Covenant were siphoning large amounts of energy from a nearby Forerunner structure. 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. 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. 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 Crawlers and Promethean Watchers 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.

Next Crimson was sent to the 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 Knights arrived in the area. Crimson beat off the foes while Miller opened the door allowing Crimson to escape on Dalton's Pelican. Crimson was then sent into a Covenant dig site at The Cauldron, a Forerunner area. The Covenant resistance was strong, leading Palmer to wonder what they were guarding. Crimson fough their way to a mysterious artifact guarded by Promethean Knights. After fighting them off, Crimson recoverd the Artifact, boarded the Pelican, and brought it back on Infinity.

Later Crimson was sent in to The Gate, a location that UNSC Marines had failed to take from the 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. . The aforementioned science team hid behind a forcefield when the 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 the Covenant and rescued her and her team.

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 Phantoms arrived carrying Sangheili Warriors and Sangheili Zealots. Crimson destroyed the Phantoms and Sangheili and were evacuated. 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 pods, but Crimson eliminated the Covenant and the turrets and continued with their mission. 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.

Hunting A Terrorist
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. Crimson was then sent to Galileo Base, a science facility on Requiem under heavy attack by Covenant forces. They managed to beat back the Covenant and drive them away from Galileo Base. Next Crimson arrived at Two Giants, a canyon with two Beam emitters, to assist Spartan squad Mountain. Beating off Covenant forces Crimson retrieved the marines and activated Forerunner technology in the towers. The Covenant responded by sending an entire fleet of foes from a CRS-class light cruiser. Palmer dropped in several Mantis mech suits which Crimson used to beat back the fleet while the cruiser was destroyed. Vol was once again located, this time re-taking the Gate location with his Covenant forces. Crimson neutralized him and several Covenant and Promethean warriors.

Chasing Jul 'Mdama
Soon after, Crimson was then sent to disable a Covenant communications array at the site the 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. UNSC Infinity found data possibly leading to Jul 'Mdama's location. The data placed 'Mdama at the Two Giants location where a tower had been retaken by Covenant forces. Activating Forerunner technology, a portal opened and Crimson stepped through. They emerged in the Fortress location and re-established communications primarily with the AI Roland. After fighting off enemy forces Crimson steped through another portal, chasing 'Mdama. 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. However, the Covenant attacked Galileo Base with the intent of recovering the gift. Crimson beat them back and activated the base's defense systems, holding back the Covenant but Prometheans translocated in the base. Crimson fought them off and left Fireteam Majestic to take the gift to Infinity.

On Crimson's next deployment, they were sent to the Gate to investigate Dr. Leslie Boyd's power fluctuations back at 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 power generators. 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. At the Refuge the science base came under attack by Prometheans, which were driven off by Crimson. A battlecruiser 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. Crimson arrived at Forward Base Magma to defend power generators from Covenant forces. After doing so, Roland found Gabriel Thorne's IFF tag in the area, and found it alone with signs of a struggle. Crimson was dropped off in an area with Covenant forces 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 the Covenant. Phantoms and Banshees then converged on Crimson's position, along with a single light cruiser.

Captured
Fireteam Crimson was eventually 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. 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 Shade turrets. Miller decided Crimson must hijack a Phantom to escape, however after entering the next area a Marine squad known as 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.
