 The Federation also used special soldiers called "Mutoids" who were humans that had undergone a special conditioning to make them absolutely obedient to their handlers and part of the conditioning involved the removal of all memory of their past lives.They functioned as pilots, technicians, bodyguards and shock troopers.Mutoids appeared to be mostly female and wore the same uniform as troopers except for a characteristic black skullcap on their heads which possibly housed cybernetic components and may have been directly attached to their bodies as part of their conditioning.
