Captain of the Spirit of Fire.
Captain James Cutter is a leader steeped in military tradition and discipline, but who balances that tradition with a genuine compassion and interest for those who serve underneath him.
A true hero of the UNSC, Cutter's military career is long and distinguished and he has sacrificed advancement up the ranks in order to remain with his crew and ship. The crew on the Spirit of Fire are more than soldiers to the captain, they are his extended family. Cutter's respect is reciprocated by his troops, who place a great deal of faith in the captain and his decisions.
