Sierra-8 "Sundowners"






Designation: Sierra-8

Codename: Sundowners

Garrison/HQ: Site-002

Role: Protection of Authority assets; Homicide, Vice, Anomaly, Cartage and Special Investigations.

Motto: "Non Poterunt" (They Cannot Prevail)

Established: 19th December, 1918

Description: MST Sierra-8 is an investigative task force assigned to protecting Authority assets from internal and external threats. MST Sierra-8 investigators are procured through exchange programs with various law enforcement agencies throughout the world, as well as hiring private investigators. However, purpose-training investigators through apprenticeships is also possible.

MST SIerra-8 Investigators are assigned to one of the various departments, namely the Homicide, Vice, Anomaly and the Cartage department. Agreements with various governments have been made to seamlessly integrate the investigators with the pertinent country's police department and/or other investigative agencies if they are taking a public case. Investigators may take on a case from a different department if they are competent in the field or has received a direct order from the Task Force Commander. MST Sierra-8 Investigators mainly work on their own and would usually take over cases from any police department or investigation agencies if they so wish. However, joint operations may be initiated with permission from the Task Force Commander.

When receiving a case, MST Sierra-8 investigators may be complemented with Crime Scene Unit (CSU) comprised of ASF personnel that has received Forensics education and training. The need for a coroner may be fulfilled by any available surgeon with relevant qualifications from the nearest site.

MST Sierra-8 was established as a counter-attack to the rising threats sourcing from the newly formed American Continental Syndicate. Initially, the Authority suffered little-to-no damage from the actions of the Syndicate in its infancy. However, in 1917, several attacks to the Authority's assets across the United States were carried out with similar modus operandi on each instance. The Board of Global Directors unanimously agreed to establish MST Sierra-8 in 19/12/1918.
