Protectors were soldiers and guards that worked in the Adeptus Mechanicus.
They were genetically engineered and augmented Humans that wore red robes and bronze masks that showed green mechanical eyes. Members of the Protectors typically carried weapon staves and served as the personal guards within a techpriest's forge. They were noted to smell of spoilt, decayed meat and oils.
