James Cutter
From Halopedia, the Halo wiki
Template:Human Character Infobox
Cutter is a UNSC Naval ship captain [1]. He may play a prominent part in the upcoming Ensemble Studios game Halo Wars to an unknown degree.
Battle of Harvest
Cutter was the commanding officer of the UNSC Spirit of Fire during the ships first battles against the Covenant at the Battle of Harvest from 2524-2531.
Because "captain" is a generic term for the commanding officer of a ship, Cutter may be almost any rank, ranging from lieutenant to admiral. It is likely, though, that he is either a Commander, or Captain, the actual naval rank.
