This weapon (see accompanying sketch) is of Boehler design, and was
first introduced in 1935. It has a high rate of fire, and may be fired either on
wheels or from its platform. It may be used as an infantry support gun in
addition to its antitank role. This gun is a standard Italian antitank weapon.
It fires HE or AP ammunition, although the former is very erratic in
performance.
The gun may be transported in any of five ways: by manpower, using
special ropes; drawn by one mule; carried on a truck; drawn behind a truck; or
divided into five packloads.

The disadvantages of the gun are: no protection is provided for the gun
crew; the traverse is limited; and the burst is less effective than that of the
British 2-pounder (40-mm).

The firing group consists of six men; gun captain, layer, gunner, loader,
ammunition handler, and a supernumerary.
The ammunition group is responsible for getting ammunition to the gun position.
