TheOTO Mod. 42 is an incendiary anti-tankhand grenade supplied to theRoyal Italian Army duringWorld War II.
The Italian Royal Army had entered the war without an anti-tank bomb of national production. Only in 1942, two models were built: theBreda Mod. 42 and the OTO Mod. 42.
The fuze consist of a normalOTO Mod. 35 hand grenade that is internally threaded and screwed to an aluminum handle which connects to the body bomb. The body is a glass container loaded with flamethrower liquid and gasoline, which shattered upon impact or at the moment of activation of the detonator. The project comes from handmade explosives built on the field by soldiers joining a normal OTO Mod. 35 with bottles filled with flammable liquid.
Soldiers were trained to hit the air vents of the tank's engine, in order to make penetrate the incendiary liquid before ignition.
