The 81/14 Model 35 Mortar was an Italian World War II infantry mortar. It was the standard weapon of the Italian Army during the war, of typical Brandt-system construction, but relatively lightweight, with good range and considered very successful. The weapon used two kinds of ammunition, a heavy high-explosive shell weighing 6.86 kg (15.1 lb) and a lighter shell weighing 3.26 kg (7.2 lb) for long distance fire.
