The Italian Army in Russia (Armata Italiana in Russia, or ARMIR) was an army-sized unit of the Italian Royal Army (Regio Esercito Italiano) which fought on the Eastern Front during World War II. The ARMIR was also known as the 8th Italian Army and initially had 235,000 soldiers.
In July 1942, the ARMIR was created when Italian dictator Benito Mussolini decided to scale up the Italian effort in the Soviet Union. The existing Italian Expeditionary Corps in Russia (Corpo di Spedizione Italiano in Russia, or CSIR) was expanded to become the ARMIR. Unlike the "mobile" CSIR which it replaced, the ARMIR was primarily an infantry army. A good portion of the ARMIR was made up of mountain troops (Alpini). While in many ways the mountain troops added greatly to the capabilities of the ARMIR, in other ways these elite mountain fighters were ill-suited to the vast, flat expanses of southern Russia.
Like the CSIR, the ARMIR included an Aviation Command (Comando Aereo) with a limited number of fighters, bombers, and transport aircraft. This command was part of the Regia Aeronautica (lit. "Royal Air Force") and was also known as the Corpo Aereo Spedizione in Russia ("Air Expeditionary Corps in Russia").
The ARMIR was subordinated to German Army Group B (Heeresgruppe B) commanded by General Maximilian von Weichs. In February 1943, after its near destruction during the Battle of Stalingrad, Mussolini disbanded what was left of the Italian 8th Army and the surviving Italian troops were unceremoniously brought home from Russia.
Mussolini sent seven new divisions to Russia for a total of ten divisions. Four new infantry divisions were sent: the 2 Infantry Division Sforzesca, the 3 Infantry Division Ravenna, the 5 Infantry Division Cosseria, and the 156 Infantry Division Vicenza. In addition to the infantry divisions, three new mountain divisions made up of Alpini were sent: the 2 Alpine Division Tridentina, the 3 Alpine Division Julia, and the 4 Alpine Division Cuneense. These new divisions were added to the 52 Motorised Division Torino, 9 Motorised Division Pasubio and 3 Cavalry Division Amedeo Duca d'Aosta which were already in Russia as part of the CSIR.
