The Royal Italian Army (Italian: Regio Esercito, lit. 'Royal Army') (RE) was the land force of the Kingdom of Italy, established with the proclamation of the Kingdom of Italy. During the 19th century Italy started to unify into one country, and in 1861 Manfredo Fanti signed a decree creating the Army of the Two Sicilies. This newly created army's first task was to defend against the repressive power in southern Italy, exemplified by rulers like Francis II of the Two Sicilies. The Army of the Two Sicilies combated against outlaws and against other armies during this time of unification. After the monarchy ended in 1946, the army changed its name to become the modern Italian Army (Esercito Italiano).

Within the Italian Royal Army were the elite mountain military corporals, the Alpini. The Alpini, which remain in existence today, are the oldest active mountain infantry in the world. Their original mission was to protect and secure Italy's northern mountain border that aligns with France and Austria. This group emerged in World War I when a three-year campaign was fought against the Austro-Hungarian Kaiserjäger and the German Alpenkorps. In World War II, the Alpini fought alongside Axis forces in the Eastern Front as well as the Balkans Campaigns.^[2]
