this is the Power-Arm. A civilian use GA used for various tasks such as heavy lifting, production line assembly, construction, minor security modifications are not uncommon for wealthier buyers. Its an earlier military model that was outmoded with the invention of a bio-humanoid mechanical frame for GAs which made this robotic frame much less efficient, more expensive to maintain, and consistently perform less proficiently compared to the newer frames. But the body movement control system is unique to this style of GA. Think Landmates from Appleseed.
