Abstract
A method and compact portable system for excavating a two-soldier fighting position is disclosed in which the method includes using a material-retention type auger to bore a plurality of spaced hollow recesses to a desired depth, placing prepared explosive charges in each bored recess, detonating the explosive charges using a remotely operable detonation device to loosen the soil in the defined pattern, removing the loosened soil, and finalizing the interior walls of the structure. The system is compact and lightweight designed to be stored within a confined carrying pack volume and features a bucket-type, hollow auger system including handle extensions capable of being quickly assembled to bore clean holes in the earth, a plurality of explosive charges, the explosive charges being stored in canisters of a size to fit into the hollow auger bit and holes bored by the auger, means for connecting to and remotely detonating the binary charges in each of the canisters.
