Digger
this clone trooper was part of the platoon dispatched to Pengalan IV, during the early stages of the Clone Wars, to eliminate a Separatist missile facility on the planet. He was given the nickname Mapper by Joram Kithe, who was stranded on the planet with the platoon's survivors after the Separatist sprang a trap. The nickname, given to help Joram communicate with the troopers, was based on the fact that the clone trooper was digging shallow graves for his fallen comrades when Joram regained consciousness. It was later revealed to Joram that Digger and his platoon-mates were actually enhanced clones, having been given additional self-reliance and initiative during their development. These enhanced troops were dispatched with observers like Joram, in order to ensure the production of clone troopers was continued.
