#michael stanforth

Stanforth lead the UNSC through the battle of Sigma Octanus IV, giving humanity a rare victory. However, the Covenant would find the location of Reach during the battle, forcing Stanforth to pursue them there. He would participate in Reach's defenses, ordering Operation: RED FLAG, a last-ditch effort to curb the Covenant invasion. He would hold the line at Reach, though he would eventually perish after his ship was destroyed.

A sidebar about this guy's messy lore:

His name is what?

Evidentially no one could agree on a name or birth date for him, which appear differently throughout the extended universe and lead to incongruous results (such as becoming a full admiral by age 17 and getting demoted four grades with no obvious reason).
