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.

History
In 2558 Crimson is deployed in a joint UNSC military operation on Requiem alongside Fireteams Castle, Majestic, Domino, and Ivy. Spartan Jared Miller is personally assigned to Crimson as their mission handler. Crimson is 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 is also given the objective to destroy four power cores acting as short-range wireless transceivers. Whilst completing their objective, Fireteam Crimson fend off multiple enemy reinforcements, including Ghosts and Wraiths. After mopping up whatever Covenant forces are left in the area, Miller sends a Pelican dropship for extraction. Commander Sarah Palmer congratulates them on their mission success, noting that they have completed their objectives before anyone else has.

Later, Commander Palmer sends Fireteam Crimson to capture a Covenant-held power station on Requiem after UNSC Marines fail to do so. They're tasked with eliminating all Covenant forces within the area. After Crimson clears out the immediate area, Miller detects strong energy readings coming from underground. He concludes that the Covenant are siphoning large amounts of energy from a nearby Forerunner structure. Miller finds the origin of the energy source and directs Crimson to it. Spartan Robert Dalton comes online and readies an orbital-strike from the Infinity to destroy the target. After eliminating all hostile threats, Crimson designates the energy source for target acquisition. The target is destroyed by Infinity, and Fireteam Crimson is extracted from the area.

Fireteams Crimson and Majestic are sent north of the UNSC's area of operations in Requiem in order to shut down Forerunner power generators. Both teams are sent to their individual locations to complete their objectives. Upon insertion, both Crimson and Majestic have their long-range communications jammed by Forerunner jamming devices. After deactivating their respective devices, their mission continues. The mission is the first time Crimson engaged Promethean forces, facing multiple waves of Promethean Crawlers and Promethean Watchers. The area is quickly swarmed with crawlers and watchers as Crimson fights to disable the arrays powering the Forerunner structure. Initiated by Palmer, the mission turns into a competition both fireteams trying to complete their mission objectives first. Majestic temporarily takes the lead, but Crimson eventually beats Majestic. As Fireteam Crimson clears out the remaining Promethean forces, Robert Dalton arrives in a Pelican dropship for Crimson's extraction.
