Munitions Propellants Residue Deposition Rates On Military Training Ranges

Abstract

AbstractTraining with live munitions is an integral component of preparing the modern military for warfare. Energetic compounds, such as propellants and explosives, are consumed during the use of these munitions. These compounds are never fully consumed, however, and the deposition and accumulation of energetic residue on training ranges is the result. This paper summarizes 10 years of research into propellant deposition rates for common military munitions used in the USA and Canada. Research indicates that the firing of howitzers and tanks leave very little residue, the firing of mortars can result in moderate deposition of propellant residue, small‐arms firing positions have the potential for significant residue accumulation, and training with shoulder‐fired rockets and 40 mm machine guns can result in dangerous quantities of unburned propellants. Residue rates vary widely for the weapon systems tested, from 10−6 % for large rocket systems to over 70 % for shoulder‐fired rockets.
