Scarlet Team was formed in 2540, with the creation of the Spartan II Class III program. Scarlet was noted very early on for being very specialized, with the children seperated into sects before training even began. In 2548, the Spartans of Scarlet were augumented, and they lost two of their number, Spartans 367 and 333. However, Scarlet remained strong, and graduated on time with the rest of the Spartans. After graduation, the all of the Spartans were given SPI Armor due to cost concerns. In 2552, after the battle of Troy II, Spartan 312 went rogue, and the two closest squads, Gold Team and Scarlet team were called in to eliminate him. However, despite being insane, 312 was clever and he lured Scarlet team out and killed them.
