The MS-06JC is a minor modified version of the MS-06J Zaku II Ground Type, which was the main machine of Zeon's Earth Attack Forces during the One Year War. Like the J-Type, it also does not have any apogee motor on its legs. It has a focus on ground battles in hot and humid wetlands, and has undergone waterproofing and changes to the legs to improve running performance on soft terrain. Furthermore, the cockpit hatch opening and closing mechanism was improved to be simpler, and a winch-type wire was hung from the upward-opening chest panel to simplify the pilot's entry and exit.
The Zaku II JC-Type was the main mobile suit deployed by the Principality of Zeon in the Southeast Asian front and fought many intense battles against the mobile suits of the Earth Federation Forces' Kojima Battalion stationed in the area.
