MI11
Appearance
MI11, or Military Intelligence, Section 11, was a department of the British Directorate of Military Intelligence, part of the War Office.
During the Second World War, MI11 was responsible for field security: protecting British military personnel from enemy agents and "fifth columnists" amongst civilian populations, in theatres of war. As such, MI11 assumed a role formerly assigned to the Field Security Police (which had itself replaced the British Army's Intelligence unit before World War I).
Section 11 was disbanded after World War II.
