The Combat Engineer Battalion represented a battalion comprised of clone troopers within the structure of the Grand Army of the Republic.

Within the 38th Armored Division, heavy artillery troopers belonging to the Combat Engineer Battalion displayed distinctive white armor adorned with brown fleurs-de-lis. Their helmets featured three broad brown stripes across the top. This visual distinction set them apart from other members of the 38th, who bore comparable markings, albeit in a muted mustard hue.
Clone combat engineers formed this specialized component of the 38th Armored Division. Their expertise lay in managing heavy artillery assets, including Self-Propelled Heavy Artillery-Turbolaser (SPHA-T) walkers and Republic Artillery Guns.
