The heavy weapons clone trooper was a type of clone trooper that was used to provide anti-vehicle support to standard infantry. They also had better armor than normal clones. When positioned well, they could take out many enemies, but were less mobile than other clones.
They were present in many units, including the 41st Elite Corps, 87th Sentinel Corps, 91st Mobile Reconnaissance Corps, 104th Battalion, 181st Armor Division, 212th Attack Battalion, 327th Star Corps, 501st Legion, 332nd Division/Company, and the Coruscant Guard.
Heavy weapons clone troopers used both Phase I and Phase II clone trooper armor. Most armor also had visors on the helmets. Some clones that wore Phase I clone trooper armor had blue markings on their armor, similar to a Clone Lieutenant. Heavy weapons clone troopers utilized either DC-15A blaster rifles, DC-15LEs, and Z-6 rotary blaster cannons.
