Note: This story is set in an alternate universe. It is set right after the rookies arrive at Blood Gulch. Church isn't killed by Caboose, and Sheila isn't destroyed. Tex has not come to the aid of Blue Team.

Location: Unknown

A peace had finally been brokered between Red and Blue, and it was about time. The Covenant were at Earth's doorstep and the petty civil war had to end. Unfortunately, compromises had to made on both sides. It had taken two weeks of negotiating but an agreement had been made. Humanity would be united against the Covenant, but not Red and Blue. It had been part of the deal put in by Earth's representative. In return for not wiping out Red and Blue Command, Earth had forced the two Commands into a helpless situation. While men stationed at Command were given pardons, Earth demanded that all frontline units were guilty of treason, and had to be destroyed. Not even the wounds of civil war would remain when the Covenant arrived, all of Red and Blue would be dead. The two generals had no choice to accept, or it was their necks.

And so the Purge of Red and Blue began. The sacrifice that had to be made for humanity's survival had begun. And at the head of the operation, Earth's most trusted soldier, Masterchief.

Location: 2km West of Battle Creek

The Pelican was moving closer to its rendezvous with Red Base at Battle Creek, and Masterchief was reviewing intel one last time. It seemed that both sides had thrown their mentally unstable platoons into a single enclosed space to see what happened. The results had not been pretty. Isolated from society it seemed that both sides that turned the protection of their flag into a religion, and so fervent were they on defending the flag, that little seemed to kill them. But Masterchief had already solved that problem.

It was dark as the Pelican hovered above Red Base as Masterchief and Alpha Team, the best spec ops kill team in the corps jumped out. The eleven of them moved towards the entrance where a red clad soldier stood. Masterchief stepped forward and called out,

"Glory to the flag"

The red soldier responded in like before leading them into the base.

"I am forbidden to pass into this hallowed chamber." the soldier said as he stopped outside a room in the centre of the complex, "It is the Housing and Altar for the flag, long may its flapiness continue."

Masterchief gave his men the signal to spread out, and within seconds they were gone, spreading across the base locating any other soldiers present.

Inside the Chamber of the Flag stood a lone soldier, draped in a robe that seemed to have been made from thinly beaten red armour. Masterchief approached him before announcing himself.

"I bring news from Red Command," he said, "they have…"

"You bring news from the Motherland" uttered the red priest of sorts, "truly a prophet has come to lead us out of the darkness and to bring the flag forward for all to behold."

"Not quite," Masterchief was getting annoyed with all this religion. This entire civil war was being fought over a bloody flag! "I bring news that the war is over."

And with that he pulled up the flag from the hallowed altar, despite the priests gasp, and broke it with his knee. The priest fell to the ground clutching his heart, as did all other Red troops across the complex. It was like a part of their soul had been ripped out.

"How could you? Blasphemy! BLASPHE…" His cries were silenced by Masterchief's pistol, as the finished the old man in one shot to the head. He spoke into his helmet radio to Alpha Team.

"Their flag is no more, begin the operation."

The members of Alpha team pulled out their weapons before going to work on the collapsed red soldiers. Bullets to the head and as clean as possible had been Masterchief's orders. And with the flag destroyed, there was no chance of them returning from the grave again.

It taken only minutes to go in and out of the base, and as Alpha Team slipped out of Red Base and began the short walk over to Blue Base, Masterchief wondered that if this was as good as it would get. The Covenant were standing on their doorstep and hi job was go finish off two armies of untrained louts. He hoped there'd be some challenge during this mission, but judging by the difficulty of the zealots at Red Base, this mission wouldn't take very long at all.
