  • Patent number: 4776255
    Abstract: A minefield breaching system comprises a projectile which is fired by trapping a round from a rifle or light mortar, and which carries behind it a length of explosive line. The end of the explosive line remote from the projectile is connected to a length of non-explosive line, the free end of which remains at the position of the user of the system. The projectile is in use fired to carry the explosive line over the minefield and the explosive line is then pulled back by means of the non-explosive line to permit an initiation set to be connected to the proximal end of the explosive line.
