Sol Intelligence Service

Forming the external branch of the UN intelligence community, the Sol Intelligence Service (SIS) is the interstellar intelligence agency of the United Nations responsible for information and intelligence gathering away from Earth, using methods such as human intelligence and cyberintelligence to do so. It is rumored that the SIS possesses a paramilitary wing of specialist NAVSOC operators for conducting raids and operations against enemies of the state.

Operating at a much higher level of discretion and secrecy than Earth-based agencies such as the CIA and MI6, a majority of the SIS's activities remain classified and unbeknownst to the public eye, operating with little oversight and freedom to do whatever they want, above the boundaries of morality.

Founded in 2080 amidst rising tensions between the Earth and Mars governments, the SIS played a key role in the UN's victory during the Martian Revolution. The SIS remained a top secret organisation and was not revealed to the public until 2092, two years after the war's end. Today it operates in primarily the same capacity, being responsible for hunting down any splinter groups as well as emplacing an espionage network across the solar system and beyond.

Leaked memos reveal that the SIS, faithful to its planetary analogues, have participated in controversial practices such as torture and drug-induced interrogation for conspirators inside the agency's custody. Despite a UN official statement in 2109 saying these methods will come to an end, it is unknown today if they have delivered.

With the leaked memos and other controversies, the SIS has an extremely low reputation in the eye of the public. For an agent to openly admit that they're a member of the SIS would be career-ending at best and at worst - as in some cases on Mars - Get them killed.
