Corporal Carter was a Confederate military prison guard at Raydin III's Military Correctional Facility-R-156 during the Guild Wars. In 2488 he was subordinate to Bellamy, a sergeant who used his superior position to bully prisoners.
Bellamy especially hated convict Tychus Findlay and punished him by forcing him to pull a mine cart. In revenge, Findlay murdered Bellamy and blamed another prisoner. Carter was fooled, and had that prisoner slowly executed. However, he still forced Findlay to pull the cart that day.
