An Expedient Method for Excavation of Foxholes

摘要

A technique involving standard demolitions and a modified entrenching tool is examined as an expedient means of rapidly constructing a foxhole. The basic design was developed in sandy, clayey silt, with limited tests in other materials. It consists of simultaneous detonation of two small charges, total energy yield being 1.5-1b TNT, one charge above the other. Except in rocky soils, which prevent augering and emplacement of the lower charge, the result is a hole suitable for immediate cover and for improvement to meet standard fox-hole criteria. Background and requirements are discussed, along with advantages and disadvantages of this method of construction. It is recommended that this technique be adopted as an expedient, and that additional research and hardware development be conducted as necessary to standardize it. (Author)
