The Italian Royal Army was reformed in 1861 and lasted until 1946. The Royal Army started with the unification of Italy (Risorgimento) and the formation of the Kingdom of Italy (Regno d’Italia). It ended with the dissolution of the monarchy. The Royal Army was preceded by the individual armies of the various independent Italian states and was followed by the Italian Army (Esercito Italiano) of the Italian Republic (Repubblica Italiana).
During the first years of World War II, Italy had only small light and medium tanks (L3/35, L6/40, M11/39, M13/40, and M15/42) tanks. When Italy declared war in 1940, Italy’s armored divisions were still composed of hundreds of L3 tankettes. These vehicles were hardly on par with the Allied tanks available in 1939 and were seriously out-classed by 1942. Better Italian tanks were produced but they were generally only available in limited numbers. Italian tanks typically suffered from poor main armaments and thin, bolted-on armour.
It was not until summer of 1943 that the Italians developed a heavier tank (the P40). However, while the P40 was in the same class as the contemporary M4 Sherman, only five were ready for combat before Italy signed the armistice that same year. The Germans acquired and used the few P40s which were produced.
To supplement the deficiencies of the main armaments on most tanks, the Italian Army made use of self-propelled guns like the Semovente 75/18 and the Semovente 75/34. The Italians also fielded some reliable armoured cars like the AB 41.
While Semovente 75/18s were available in some numbers in North Africa, the more potent Semovente 75/34s, Semovente da 75/46s, Semovente 90/53s, Semovente 105/25s, and Semovente 149/40 were available in limited numbers or not at all prior to the armistice. Like the P40, the Germans acquired the few better quality self-propelled guns manufactured prior to the armistice and even continued to manufacture some after the armistice.
The main infantry weapons were Carcano rifles, Beretta M1934 and M1935 pistols, Bodeo M1889 revolvers, Breda 30 light machine guns, Breda M37 and Fiat–Revelli Modello 1935 heavy machine guns, and Beretta Model 38 submachine guns. Second line units frequently made use of captured equipment such as Lebel Model 1886 rifles and, for colonial troops, Schwarzlose MG M.07/12s and Steyr-Mannlicher M1895 rifles, provided by Austria as war reparations after World War I
