Wrench
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 had the highest level of mechanical aptitude among his fellow platoon-mates. It was later revealed to Joram that Wrench 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.
