Clone Commander, also known as clone trooper commander, was a rank in the Grand Army of the Republic held by clone trooper officers who led regiments of 2,304 troopers. The sixteen clone commanders in each corps were in turn commanded by their respective Jedi General. Clone Commanders in standard Phase I armor wore clone trooper armor featuring four yellow circles on the left chestplate as well as a stripe of yellow down the length of each arm, vertically up the middle of the helmet and laterally around the visor.
Advanced Recon Commandos who served as commanders were known as Clone ARC Commanders. Clone trooper pilots could also serve as commanders. During the Clone Wars, Clone Commanders served under Jedi Generals and, like the rest of their clone brethren, fought against the Confederacy of Independent Systems. Near the end of the war, all clones were ordered by Supreme Chancellor Sheev Palpatine to betray and kill their Jedi officers.
