A clone heavy trooper
The clone heavy troopers were heavy weapons specialists, Advanced Recon Commandos in the Grand Army of the Republic during the Clone Wars, albeit of unknown relation to ARC heavy gunners. Some Commanders, such as Commander Bacara, were equipped with clone heavy trooper armor such as the cheek plating, and Kamas.
The heavy weapons commandos carried Merr-Sonn PLX-1 missile launchers, blaster pistols, V-1 thermal detonators, HX2 antipersonnel mines and other ARC trooper equipment. The heavy troopers handled the anti-vehicle and anti-armor duties of the Grand Army of the Republic. They should not be confused with the clone heavy gunner
