After graduating from high school in Baku, Azerbaijan with the "excellent" grades in all subjects (including the Azerbaijani and German languages), in June 1941, Enver Mamedov joined a fighter pilot school. After Hitler's invasion of the USSR in 1941, Enver asked to be sent to the front line, but was instead sent to be trained as a military translator at a GRU school. After seeing some action first as a Sr. Sergeant, later as a Sr. Lieutenant, at the Soviet Union's Caucasus Front, Mammadov was sent to work with the USSR Commissariat for Foreign Affairs, where he was posted to the Soviet embassy in Italy as the press secretary. According to Mammadov himself, he was probably selected to that position because he spoke Italian, in addition to German, English, and French.
