Auror (MACUSA)

Like the British Ministry of Magic and several other wizarding governing bodies, the Magical Congress of the United States of America, but unlike their British counterparts, rather than being "dark wizard catchers", they seem to serve MACUSA in a more generic manner, responding to large-scale threats to the security of wizarding America whatever. Also, unlike the British Aurors, rather than limiting themselves to capture dark witches and wizards, they seem to serve both as an equivalent to the British Auror, and as their work with the Major Investigation Department indicate, also fills the role of the Magical Law Enforcement Squad, arriving at the crime scene to see justice done even when there is no evidence of Dark Magic yet risk of endangering wizarding secrecy. They seem noticeably more militant than British Aurors and will not hesitate to use lethal force if ordered to do so, being swift and ruthlessly efficient.
