Katarn - class commando armor " Katarn " - class commando armor was armor used by clone commandos during the Clone Wars . It was named after the predatory animal from Kashyyyk . It weighed 20 kilograms and could cost up to 100 , 000 credits on the black market . This armor was more expensive and provided better protection than standard clone armor , due to the special composition and novel chemical properties of its armor plates , along with the inclusion of deflector shields . It was also designed for easy bacta injection via handheld dispensers . Katarn Armor was often highly customized by the clone commandos who wore it . History . Mark II " Katarn " armor , issued circa four months after the Battle of Geonosis , was reinforced against Verpine shatter guns and EMP weaponry , following recommendations made by Omega Squad after their tour on Qiilura .
