He had a medal of valor and was wounded three times in the battle of Rork's Rift.
During the Guild Wars he was given the task (along with the taller Sergeant Orin) of determining whether Old Family heir Ark Bennet had been kidnapped and pressed into the military under the name Ryk Kydd.
He and Orin met "Kydd" shortly after the Battle of KIC-36, a poorly-chosen moment as Kydd's platoon had lost half its membership there. Corly called Kydd by his real name, Ark Bennet, but Kydd didn't fall for it. When he "invited" Kydd to a talk, the platoon's commander, Sergeant Tychus Findlay, intervened. Kydd defused the tension and Corly and Orin took him to the command center.
While there they questioned him on a claim he had made previously, when he told Major Lionel Macaby that he was really Ark Bennet. Kydd didn't deny this, but said he had lied. Corly admitted that Kydd didn't resemble Bennet much, but his retinal scan was a perfect match. Kydd insisted on remaining with the Confederate Marine Corps, however. They agreed to allow Kydd to remain in his new life.
