H-84: Creating Mouseholes

Previous: H-83: Breach Locations

H-84. Mouse-holes provide a safe means of moving between rooms and floors. C4 plastic explosive can be used to create mouse-holes when lesser means of mechanical reduction fail. Because C4 comes packaged with an adhesive backing or can be emplaced using pressure-sensitive tape, it is ideal for this purpose. When using C4 to blow a mouse-hole in a lath and plaster wall, one block or a strip of blocks should be placed on the wall from neck-to-knee height. Charges should be primed with detonating cord or modernized demolition initiator (MDI) to obtain simultaneous detonation blowing a hole large enough for a man to fit through.
