An impact initiated attachment device for attachment to a target, comprises a housing having a front face which abuts against the target in use, one or more fasteners, a drive mechanism for driving the fasteners(s) from a first position within the housing to a second position protruding from the front face of the housing, and a trigger mechanism for triggering activation of the drive mechanism comprising a trigger extending from the front face of the housing. The device is particularly useful in Explosive Ordnance Disposal (EOD) and demolition for attaching one or more disrupters to a target for disposal.

Mine neutralization provides for radio control of a small boat having associated therewith: a projection mounted onto the boat and pointing forward; a primary magnet; a housing holding the primary magnet and joined at the front end of the projection; a fluid-dynamically shaped explosive device detachably attached underneath the boat; at least one secondary magnet affixed to the explosive device; and, a rope or cable tautly connected at its upper end to the primary magnet and at its lower end to the explosive device. The boat journeys near a floating mine to bring about magnetic interaction between the primary magnet and the mine. The primary magnet magnetically attaches to the mine, and a pulling force is exerted on the explosive device. The explosive device detaches from the boat, moves toward the mine, and magnetically attaches (via at least one secondary magnet) to the mine.
