Katarn-class commando armor, also known as Katarn-class armor, represented a sophisticated and durable form of clone trooper armor. It was primarily issued to clone commandos serving the Galactic Republic during the Clone Wars, and its use continued under the Galactic Empire throughout the Imperial Era.
Clone commandos received Katarn-class armor sets, which included backpacks designed to carry grenades and equipment for sabotage missions. The commandos had the option to personalize their suits with different colors. The armor's designation was inspired by the Katarn species, which originated from the planet Kashyyyk. The Mk I Katarn-class Commando Armor stands out as one particular version of the Katarn-class armor.
Throughout the Clone Wars and into the Imperial Era, clone commandos actively utilized Katarn-class commando armor. The members of Clone Force 99 sported modified versions of Katarn-class armor. During the Imperial Era, mirroring the practice of standard clone troopers returning their armor to a plain white state, clone commando armor often adopted a similar uncolored appearance. However, Clone Commander Scorch was an exception and was permitted to keep his original colors. Furthermore, commandos serving in the Imperial royal guard wore armor distinguished by grey markings. Notably, a number of commandos equipped with blank armor collaborated with the grey-accented royal guard at Mount Tantiss.
