The Gundam Sandrock was created at the L4 colony cluster, using the resources of the wealthy Winner family. This powerful, heavily-armored Gundam is designed for hand-to-hand combat, and is particularly well-suited to desert conditions. Its main weapons are the curved, heat-radiating blades of its heat shotels; the Sandrock is strong enough to wield one of these huge blades with a single hand, or strike simultaneously with both. The Sandrock can mount its backpack, shield, and both heat shotels on its forearm to perform a deadly pincer attack called the "cross crusher."
