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.
