The cannone da 65/17 modello 13 was an artillery piece developed by Italy for use with its mountain and infantry units. The designation means 65 mm calibre gun, barrel length 17 calibres, which entered service in 1913. The designation is often shortened to cannone da 65/17.
The Cannone da 75/27 modello 11 was a French-designed field gun produced in Italy prior to World War I. It was introduced in 1912, designed by Joseph-Albert Deport. It was taken into service by Italy for use with its Alpine and cavalry troops going into World War I, and was built there in large numbers. The gun was designed with two notable features. It was the first artillery piece to introduce the split trail, as well as the last to utilize its novel dual-recoil system. The former became a very popular feature on artillery pieces through to the modern day. The later, while functional, did not get repeated. The dual-recoil system consisted of a small tubular recoil under the barrel which in turn traveled in a traditional rectangular cradle. This lessened heat transfer from the gun barrel to the recoil mechanism effectively, but was not necessary for the added complexity.
The Cannone da 47/32 mod. 1935 was an Italian artillery piece that saw service during World War II. It was originally designed by Austrian firm Böhler, and produced in Italy under license.

The Cannone da 149/35 A was a heavy gun which served with Italy during World War I and World War II. It was already an old-fashioned weapon when introduced around 1900. It lacked a recoil system of any kind and could not traverse. The gun recoiled up two ramps placed behind the wheels and had to be re-laid after every shot. Wheel plates were added to absorb more recoil energy and to help the gun cross soft ground. Despite these serious drawbacks, being cheap and easy to manufacture, the gun was produced in large numbers and saw extensive use during World War I. Some 895 were still in Italian service in June 1940 and saw use in World War II in Italy and North Africa, as well for coastal defense in France and the Balkans. Weapons captured by the Germans after the Italian surrender in 1943 seem to have been scrapped or ignored as there is no record of them in German service.
