General Martok

General Martok comes from a family of commoners who had served the Klingon Empire as soldiers for generations but his father wanted him to be an actual officer. Thanks to Kor, Martok could only serve as a civilian laborer and not a soldier until he earned a battle field commission when his ship was boarded by Romulans. Sadly Martok's father didn't live to see that day.
