USE OF THE PG-7 SERIES ROCKET AS PART OF AN IMPROVISED EXPLOSIVE DEVICE

Abstract

The purpose of the article is a comprehensive analysis of the theoretical provisions and practical problems of using
the PG-7 series shot as a component of an improvised explosive device, providing appropriate recommendations.
Methodology. The reliability of the results and conclusions obtained is provided by general scientific (empirical and
theoretical) and special research methods. So, in particular, theoretical general scientific research methods (analysis,
synthesis, generalization) characterize scientific and information sources on the research topic, clarify the level of
sufficiency of profile information in them for practical use. Using empirical methods (observation, description, etc.)
and special research methods, the parameters are described and the features of the described examples of improvised
explosive devices and their remains at the explosion site are highlighted. The systematic approach to conducting
the study ensured its comprehensive nature and made it possible to combine the individual results of the study (for
different constructive versions of improvised explosive devices) into a single whole. Scientific novelty. The design
features of individual parts and assemblies of atypical improvised explosive devices created on the basis of the
marching and starting powder engines of the PG-7 series and the 82-mm mortar mine and the POM-2 anti-personnel
mine are indicated, and the most characteristic remains at the site of the explosion of the described modifications to
improvised explosive devices, which will help the identification process and establish the mechanism of the explosion.
Conclusions. A comprehensive description of the two main variants (modifications) of improvised explosive devices
is given, among the components of which are the design of the marching and starting powder engines of the PG-7
series shot, the 82-mm mortar mine and the POM-2 anti-personnel mine. The design features of individual parts and
assemblies of the indicated improvised explosive devices are indicated. It is noted that the design of the examples of
explosive devices illustrated by us is atypical and requires the appropriate knowledge of a forensic expert in order to
avoid providing false (incomplete) conclusions that will affect the process of pre-trial investigation. Typical remains
at the site of the explosion of these modifications of improvised explosive devices, by which they can be identified,
are considered. The remains of the two main types (modifications) of the subject of research are compared, the results
are illustrated. At the same time, it was noted that the remnants of the spent marching and starting powder engines
of the PG-7 series shot are closer to the explosion site than the remnants of an anti-personnel mine flying over a
much greater distance. Recommendations of a practical and applied nature have been formulated that will help to
avoid mistakes, solving the issues of classifying the investigated explosive devices as an integral structure, and not
individual devices (ammunition) in the framework of a forensic explosives examination, and will also be useful not
only to forensic experts of research institutions working on such direction as the study of explosive devices, traces and
circumstances of the explosion, but also to other law enforcement officials when examining the scene of an explosion
caused by the indicated improvised explosive devices, and subsequent pre-trial investigation
