Arm Slave - History

History

The Arm Slave is a development of the Reagan Administration Strategic Defense Initiative's research in the 1980s into powered exoskeletal suits to increase the ground soldier's combat capability. Called the XM3, the first powered suit was nothing more than a powered exoskeleton sized around 2 meters tall. This proved to be of low combat effectiveness as it offered little advantage in protection in exchange for its limited mobility. This early prototype was hampered by the lack of a suitable power source that did not burden the unit past its useful load.

The designers took an unorthodox approach in the development process at this point. While technology usually is refined to become smaller and more compact, the successor XM4 project took an opposite direction. By increasing the size of the suit from 2 meters standing to around 8 meters, the designers were able to change the power source from an electrical battery system to internal combustion engines. With the advances in material sciences and engineering at the time, the tremendous increase in power-to-weight ratio of diesel engines and the artificial muscles constructed from electroactive polymers (EAPs) (later refined and called Muscle Packages) made the XM4 a viable weapons platform with a sizable payload. By increasing the payload of the powered armor, and expanding the capabilities of the unit by various electronic warfare packages and options the first generation, and inaugural Arm Slave was introduced to the world as the M4.

One of the most notable aspects of the development of the Arm Slave is the curiously short development span. It took only three years from start of the XM3 project to the resulting M4, an unheard of development span in weapons technology when equivalent civilian robotics was struggling with bipedal motion. The unnatural advance in technology was attributed to extraterrestrial sources by some publications, and managed to fuel a new generation of conspiracy theorists. Soon, the explosive evolution of the Arm Slave in the battlefield reduced its prominence to just another high tech weapon system, alongside the cruise missile and stealth jet fighters.
