DD was a clone commando that served in the Grand Army of the Republic. The commando was apart of Lambda Squad. DD, like all the commandos, went through vigorous training. During an exercise, one of Lambda's squadmates, RC-8028 or Two-Eight, was killed. It is possible that DD was the replacement for the squad. During the squad's first mission, to the Battle of Geonosis, DD, alongside O-Four and Sev were killed, leaving Sergeant Niner the only survivor.
