Blue Team
From Halopedia, the Halo wiki
Blue team is the usual designation for the Master Cheif's squad. Originally comprised of Spartan 117 John, Spartan Sam, Spartan Kelly, Spartan Linda, and Spartan Fred. After Sam's death on the convenant ship, he was replaced by Spartan Kurt. After that, kurt was presumed dead, when he was taken by Ackerson to train the Spartan III's. It is unknown who takes kurt's place after this.
Blue team is usually comprised of these five members, but has been changed in different occasions. It is the name of the team John is in, for the most part.
