The clone commanders, especially those trained to be ARC commanders by ARC trooper Alpha-17, were always an anomaly in the Republic clone army, what with their greater independent thought and creativity than the average clone trooper. Commander Gree, however, stood out more than the average commander. He possessed a keen interest in alien species and cultures, for more than one reason. He personally enjoyed learning about them for his own intellectual interests, but he also used his knowledge to learn new lessons about military strategy, and to help his unit, the 41st Elite Corps, forge alliances with local alien populations.
