Clone heavy assault trooper
The clone heavy assault troopers, also referenced as clone heavy troopers, and also anti-air clone troopers, functioned as specialists in heavy weaponry within the Grand Army of the Republic throughout the duration of the Clone Wars.
Description

The troopers known as clone heavy assault were heavy weapon specialist who specialized in the operation of mobile emplacement armaments. Frequently, clone heavy troopers were equipped with Merr-Sonn PLX-1 portable missile launchers, DC-15S, V-1 thermal detonators, HX2 antipersonnel mines, in addition to other equipment typically associated with ARC troopers. The heavy troopers took on the responsibilities of anti-vehicle, anti-airborne, and anti-armor defense for the Grand Army of the Republic.

A comparable unit existed in the form of the clone heavy gunner.
Certain Commanders, such as Commander Bacara, were outfitted with clone heavy trooper armor, including features like cheek plating and Kamas.
