Etledyne Organic Synthetics are one of the most cost-effective ways to supply private parties with drone labor. The artificially created bodies are custom tailored for the tasks at hand, and can manage a variety of roles, including waste-disposal, manufacturing, office work, combat, and even housekeeping and child-care duties.
Being cybernetic organisms, they use integrated electronics in concert with their synthetic bodies. Some models use rechargeable batteries while other more independent models actually consume food to convert to energy. Usually these are the military models, where power sources may not be so readily available.
This particular model, the EOS-s is designed for private armies and security. The chitinous armor plating that grows off of the body is equipped with several modular slots where additional equipment like radar, shields, rockets, or extra armor may be placed. However, usually soldiers opt to "dress them up" with their own military's items, (such as the ammo bags and satchels placed on the EOS-s drawn) rather than buy the parts from Etledyne.
