Blue Team personally spearheaded the defense of Earth in late 2552, early 2553. Most of the defeats of the Covenant were made by Blue Team personally. Heading military operations all across the Galaxy against the Covenant over the entire war, they knew the Covenants' weaknesses and knew how to expertly exploit them. Their abilities led to the conclusive defeat of the Covenant, Flood, and enemy Human forces in 2553. The survivors were deemed heroes of Humanity, and the dead were even more so for giving their lives so that billions others may live.
