Regimental commander, or clone regimental commander, represented the third-highest military rank achievable by a clone trooper commander within the Galactic Republic's Grand Army. Tasked with leading regiments of clone troopers in conjunction with a Jedi Commander, these clone regimental commanders were identifiable by the yellow designs present on their Phase I clone trooper armor during the initial stages of the Clone Wars fought against the Confederacy of Independent Systems. As outlined in the Grand Army's Order of Battle, clone regimental commanders answered to senior clone commanders, while clone battalion commanders reported to regimental commanders. One example of a clone regimental commander was CRC-09/571.
The rank of clone regimental commander was initially introduced in Shatterpoint, a novel authored by Matthew Stover and released in 2003.
