APPLICATION YM-IV YM-IV is an anti-personnel jumping mine with a cylindrical cast-iron case and removable fuze mounted on the top. The removable fuze will be activated by pressure force about (7-15) kg and traction force about (4-8) kg. When the fuze is activated, the detonator fires the propelling charge and the mine body is projected about 50 cm into the air. The inner traction fuze fixed to the bottom of body fires the detonator and the booster. When the body is exploded, the metal fragments are scattered in all directions.
