MI numbers

From Wikipedia, the free encyclopedia

For the television series, see Mission: Impossible.

During the Second World War, British secret services were divided into numbered sections referred to as Military Intelligence, department number X: this was shortened to MIX. MI5 (officially the Security Service) and MI6 (officially the Secret Intelligence Service) are often still referred to using these names by members of the general public and the media.[1] [2]

The numbers were as follows:

• MI1: Code-breaking (see GCHQ)
• MI2: Russia and Scandinavia
• MI3: Eastern Europe
• MI4: Aerial Reconnaissance
• MI5: Domestic intelligence (now Security Service)
• MI6: Foreign intelligence (now Secret Intelligence Service)
• MI7: Propaganda
• MI8: Military Communication Interception (see GCHQ)
• MI9: Undercover operations, POW escape
• MI10: Weapons analysis
• MI11: Field security police
• MI12: Military censorship
• MI13: Reconnaissance
• MI14 and MI15: German specialists
• MI16: Scientific Intelligence
• MI17: Military Intelligence "Head Office"
