The Sandrock was constructed by Instructor H in the L4 colonies under the financial support of the Winner family. Designed for operations on land, especially in a desert environment, it has high combat capabilities and excels in melee combat with its strong armor that is more robust than other Gundams’. In addition, it has advanced communication and information analysis systems as it was designed as a commander unit and tasked to be the core of the command system for the Maganac Corps and the five Gundams. Lastly, a sub-camera that functions in sandstorms is installed on the forehead.
The XXXG-0SR Gundam Sandrock (aka Sandrock or Gundam Zero-Four) is a mobile suit featured in the anime series Mobile Suit Gundam Wing and is piloted by Quatre Raberba Winner.
