Nurse Model

The Nurse model is a bit open to derision in places, specifically places that don't know any better.
  They'll figure it out when they've eaten a bullet and it's smashed in half of their internals, and they're seconds away from the last of their fluids leaking out onto the floor.
  Nurse Models have, and are able to expand upon, an expansive suite of diagnostic and self-repair tools for both themselves and others. Not only that, they also have built-in stores of nanites to do repairs both internal and external.
  Of course, this means that they are meant for the care and maintenance of Ms exclusively, but it's not uncommon for Nurse Models to have extensive knowledge of organic systems as well, making them perfect all around medics.
