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.
