Armament All 120 mm smoothbore mortars. Development: By Simmel Difesa for Italian and other Brandt-pattern 120 mm mortars. Description This is a conventional White Phosphorus (WP) smoke bomb. It has a steel body filled with WP and is closed at the forward end by an adaptor, which incorporates a thin steel tube on the axis of the bomb. This tube is filled with a charge of Composition B and the adaptor is threaded to accept a percussion fuze. The tail end of the body is recessed and threaded to accept the extruded
steel tail unit which comprises a perforated tail tube and 12 fins. The propelling charge consists of a primary cartridge, inserted into the tail tube and four secondary charges fitted around the tail tube in horseshoe containers. The bomb is drop-fired in the usual way. On impact with the target area, the filling of Composition B is detonated, providing sufficient force to break open the shell and distribute the WP around the point of impact. The WP then ignites spontaneously giving a smoke cloud and incendiary effect. Manufacturer Simmel Difesa SpA.
