Swedish Military Intelligence and Security Service

Military Intelligence and Security Service (Militära underrättelse- och säkerhetstjänsten), MUST, is a division of the Swedish Armed Forces Central Command. It is the main foreign intelligence agency in Sweden and as such is responsible for providing intelligence to both the Government of Sweden and the Supreme Commander of the Swedish Armed Forces. It is also the Military Security Service which means that it is managing the security for vital divisions and agencies of the Swedish Armed Forces.

MUST consists of three departments, Underrättelsekontoret UNDK (Intelligence Office), Säkerhetskontoret SÄKK (Security Office) and Kontoret för Särskild Inhämtning KSI (Office for Special Collection).
 * UNDK's task is to acquire relevant information which can be used as basis when the Central Command and Ministry of Defence makes decisions, and aids deployed Swedish military units.
 * SÄKK's task is to work with signal protection, investigating persons and information protection.
 * KSI's task is to conduct espionage by HUMINT. Little is known about KSI, as it is only mentioned once in Swedish law.

MUST also co-operates with other defence intelligence agencies, such as the Swedish National Defence Radio Establishment (FRA), the Swedish Defence Research Agency (FOI) and the Swedish Defence Materiel Administration (FMV). In contrast to common belief FRA, the Swedish National Defence Radio Establishment, is not a part of MUST but a civil agency.

Current Director of MUST is Major General Gunnar Karlson. Even though MUST is technically a part of the military, a majority of the staff is civilian.
