摘要
A lightweight man-packable system for breaching in a single application reinforced structure such as steel reinforced concrete (SRC) walls. Embodiments comprise two explosive charge arrays installed in a housing that is abutted against a wall using either studs or prop sticks. One embodiment positions a secondary linear shaped charge (LSC) or self-forming fragment charge (SFF) spaced apart from a primary high explosive (HE) charge that contacts the structure. The HE is detonated to remove concrete in a pattern sufficient to enable a human to transit the resultant opening and the secondary charge cuts the reinforcement shortly thereafter enabling a “clean” breach via a single application of the system. In select embodiments the second array is positioned on a hinged frame to increase stand-off from the first array and moves into place to detonate over the opening immediately after detonation of the first array.
