Kontoret för särskild inhämtning

Kontoret för särskild inhämtning (KSI), "The Office for Special Collection", is part of the Swedish Military Intelligence and Security Service (MUST, Militära underrättelse- och säkerhetstjänsten) and also one of the most secret parts of the Swedish Armed Forces. The previous name, until the early 1990s, was Sektionen för särskild inhämtning (SSI), "The Section for Special Collection".

The main task of the office is that of liaison with foreign intelligence organizations and, to a lesser degree, espionage through HUMINT.
