The Italian Military Information Service (Italian: Servizio Informazioni Militare, or SIM)[1] was the military intelligence organization for the Royal Army (Regio Esercito)[2] of the Kingdom of Italy (Regno d'Italia) from 1900 until 1946, and of the Italian Republic until 1949. The SIM was Fascist dictator Benito Mussolini's equivalent to the German Abwehr.
