Terran intelligence

The Terran Federal Republic has an extensive network of intelligence agencies, comprising over two dozen Federal Administrations. These include ministerial and independent agencies. The majority of Terran intelligence administrations are part of the Directorate of Security and Intelligence, the principal Federal intelligence community. Some agencies classify their data, notably the number of employees, however estimates by the Galactic Beholder place the total number of employees at 6 million and the budget at 4,5 trillion Sols.
Terran intelligence was initially aimed at controlling the Terran population, especially during the First Commonwealth era. From the 22nd century to the First Contact War, the intelligence network shifted towards a role of controlling administrative services. During the First Contact War and the Era of Isolation, it became imperative to spy on aliens and prevent any leaks towards foreign states. The surveillance of the newly-founded dominions also became a priority. In the years immediately preceding the Terran involvement in the Great War and during military operations, the intelligence agencies shifted to accomodate for a great number of military special operations and the espionnage of enemy military targets. Since the end of the Great War, the intelligence network has had to adapt to make all of these tasks possible and effective. This led to a sharp increase in the intelligence budget throughout the 2650s, despite the end of the war. Today, the main opponents of Terran intelligence are the foreign services of the Mirdesh Confederacy, Surben Republic and Ur-Han: the Confederacy Security Directorate, the National Office of External Operations and the Royal Intelligence Authority Lay respectively.
