Jakob Keyes (Earth-2042)

"Men like him will save this Republic, you know. We need more like Keyes."

- Admiral Petron Cole

Captain Jakob Keyes (service number 01928-19912-JK) was a male Human captain and one of the most brilliant tacticians in the GRSC Navy. He commanded great respect as a highly skilled strategist and inspirational leader to those under his command. His many decorations, thirty-five years of combat experience against the Covenant, Insurrectionists and the Confederacy of Independent Systems combined, and ability to keep a secret made him an almost natural choice to command the Pillar of Autumn and its secret cargo.

He was renowned as a war hero for his development of the Keyes Loop tactic, and leading the Battle of Installation 04.
