Commodore William Vickers

Commodore William "Bill" Vickers was a professor at both the UE Training Academy and, later, the IDF Academy, who taught Orbital Tactical Theory until at least the age of 95. At one point he became distressed when he believed there was a new Swarm invasion, and pulled the fire alarm at the school.

Vickers had fought in the First Swarm War, and had blown up half a dozen Swarm capital ships with his own light cruiser, the ISS Albion, before they destroyed it. He drifted in high-earth orbit in just his space suit for three days before IDF found him.
