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.
A lightweight design, the 65 mm gun was designed for use in difficult terrain and extreme weather conditions. The barrel had a 17 calibre length, and was designed for firing low-trajectory shots. The carriage was likewise simple in nature, consisting of a single trailing arm and solid-rim spoked wheels for horse draft. The weapon could be broken-down into five loads for transport. A simple folding gun shield was also provided in 1935.
The 65 mm gun was first accepted into service with Italian mountain troops in 1913, and it served with them throughout World War I. Replacements arrived in the 1920s and the gun was transferred to the regular infantry. It was well liked by the infantry due to its minimal weight and high reliability in adverse conditions. Despite its light calibre, it served through World War II with Italian forces as a close support weapon. It was effective also mounted on truck, in North Africa, as anti-tank artillery.
