Jacob Keyes (Earth-2915)

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

- Admiral Preston Cole

Captain Jacob Keyes (service number 01928-19912-JK) was a commanding officer and one of the most brilliant tacticians in the UNSC 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 UPP, and ability to keep a secret made him an almost natural choice to command the UNSC 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.
