The Class-III cyberarm is a commercial prosthetic used by many civilians in the Koprulu Sector. Developed by Rel-X Inc., this cyberarm is made to be a cheaper alternative that military grade ones used by the Dominion. Mainly for commercial use instead of military purposes, the Class-III lacks armor plating and powered armor level strength enhancement. However, they have been known to be modified to conceal various small arms by black-market technicians. Some of the most popular modifications range from retractable blades, micro-lasers, small arms, and even explosive charges within the forearm component (Beast Wars: Rattrap).
