The 65 mm gun was first accepted into service with Italian mountain troops in 1913, and it served with them throughout
World War I. It was used in the
Fiat 2000 heavy tank which saw action in Libya. 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, particularly on captured
Morris CS8 in North Africa, as
anti-tank artillery. Guns captured by the Germans after the Italian defeat were given the designation
6.5 cm GebK 246(i). Some were fielded by the
Ecuadorian Army during the
Ecuadorian–Peruvian War. == See also ==
