This self-propelled gun was built with riveted steel plates and a crew of three – driver, loader/radio operator, and tank commander/gunner. The main gun was a derivative of a 75mm L/18 gun, itself a quite modern divisional artillery piece. The gun had a muzzle brake, and there were several observation and aiming systems (binoculars, periscopes and others) for the crew. Only one roof-mounted machine gun was fitted for close defence, though sometimes it was omitted. Initially this was a 6.5 mm Breda but was later upgraded to an 8mm model. A Radio model RF1 CA with interphone was usually fitted.
