RC-1138

Republic Commando 1138 or Delta-38 was an elite clone commando in the Army of the Republic during the Clone Wars. He was nicknamed "Boss" by his fellow clones and was the commander of Delta Squad.

Because of his role as commander, Boss received the heightened independence and advanced training available only to clones that were designated to be squad, battalion or legion commanders. On Kamino, Boss was separated from his clone brethren to train in a special class, where he developed into a strong and capable leader. The Kaminoan cloners ensured Boss was allowed to develop extra intelligence and a capacity for tactical thinking, in addition to the ability to coordinate and work alongside a four-clone commando unit.
