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. Possessing a paramilitary wing, SIS works in tandem with the Sol Defence Corps' NAVSOC division for conducting raids and operations against enemies of the state.

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 in 2089. The SIS remained a top secret organisation and was not revealed to the public in 2091, 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.
