Blue Team (Earth-4001)

"You 'Spartans' have put quite a dent in our efforts to liberate the frontier worlds...I didn't believe it until I saw the video. All by the same four-man team. Some said 'Blue Team' was a myth."

- General Graves about Blue Team's activity

Blue Team is a semi-constant unit composed predominantly of Spartan-IIs under the operational command of UNSC Naval Special Warfare Command, generally consisting of around four members. It was led by John-117 for most of its activity during the Human-Covenant War, though after John's involvement in the Battle of Mombasa, the role of leader was taken up by Fred-104.

Blue Team has participated in more than two hundred and twenty military operations since its activation in 2525 against a plethora of foes, including Insurrectionists, the Covenant, and various Forerunner constructs. The team is exceptional even among the Spartan-IIs due to their involvement in many of the most pivotal engagements of both the Insurrection and the Covenant War.

History
The history of Blue Team is the same as its mainstream counterpart up until the end of the Human-Covenant War in 2553.
