The Petite-Mobile was a small civilian mobile suit used for construction work on the Moon. Because of its use, the suit was much smaller than military machines and due to the open seat cockpit in its torso, wearing spacesuit was required. Despite the machine was not intended for combat, it could be equipped with a small mega particle cannon. A EFF's Petite-Mobile equipped with extra armor and hyper beam gun was seen at the Earth Federation's Torrington base in U.C. 0096.
