Virtual Reality (VR) is an amazing tool in the field of interaction, simulation, and entertainment between humans and computers. This technology is often used for recreational purposes in combination with physical activities. The main objective of this study was to compare intermittent training with continuous training on the shooting range. The first part of the article presents the essence of virtual reality and the possibilities that arise from its use. Then the created virtual environment, in which the shooter is located, and the way the study has been carried out are presented. The attempts of the participants were shown and evaluated. The realistic physics of movement and environment interactions have been designed into this map. The main aspects of the modelled and programmed shooting range were presented and their use has been described. The following section describes the research process and the analysis of the results of the test carried out on eight participants who had not previously been exposed to virtual reality. The test subjects were divided into two groups, one intermittent training and the other continuous training. The results of these groups were compared to assess which forms of training in a virtual reality environment were more beneficial.

During shooting operations in garrison shooting ranges, a phenomenon of random deflection of the bullet flight path was noticed which may cause secondary reflections from accidentally hit technical and ballistic shooting range elements and the ground of the actual plane of the shooting range (ricochets posing a threat to people and property within the shooting range and safety zones). Minimisation of this phenomenon must be considered during the design and operation of the shooting ranges. In 2020-2022 the Military Institute of Armament Technology (Zielonka, Poland) carried out tests with the aim of determining the impact of the shooting target or military target material or design (hereinafter referred to as the targets) on the risk of occurrence of modifications of bullet trajectory that cause the bullets to leave the shooting zone. The paper presents example results of these tests that show, but are not limited to, that the reasons to modify the direction of the bullet path after target penetration and any ricochets include: target material (flat or corrugated sheet metal, cardboard, plywood, etc.), target wooden legs, and even metal elements fixing the legs to the target. On the basis of the test it was shown that the metal targets prohibited on intermediate lines may cause significant deflections of the bullet flight path after penetration and dangerous ricochets. Due to the reason presented above, the metal targets are placed on the last line of targets before the main bullet trap only where the technical and ballistic parameters of the bullet trap ensure that any ricochets are captured. It was stated that the contact targets used on intermediate target lines and provided with wooden legs may cause bullet trajectory changes comparable to or even greater than in the case of the prohibited metal targets. To this end it is advisable to establish legal framework covering the ballistic inspection of the target materials to be used in garrison shooting ranges.

Podczas prowadzenia strzelań na strzelnicach garnizonowych zaobserwowano zjawisko losowego odchylania toru lotu pocisków, które może powodować wtórne odbicia od przypadkowo trafionych elementów techniczno-balistycznych strzelnicy oraz gruntu płaszczyzny rzeczywistej strzelnicy (rykoszety stanowiące zagrożenie dla ludzi i mienia na strzelnicy i w strefach ochronnych). Projektowanie i eksploatacja strzelnic musi uwzględniać minimalizację tego zjawiska. W latach 2019÷2022 przeprowadzono w Wojskowym Instytucie Technicznym Uzbrojenia badania, których celem było ustalenie wpływu materiału i konstrukcji tarcz lub figur bojowych (dalej nazwanych tarczą) na zagrożenie wystąpienia zmian trajektorii pocisków, skutkujących opuszczeniem przez pociski strefy strzelań. W artykule przedstawiono przykładowe wyniki tych badań, które pokazują m.in., że przyczynami zmiany kierunku lotu pocisku po przebiciu tarczy i ewentualnego powstawania rykoszetów są: materiał, z którego wykonano tarcze (blacha płaska lub falista, tektura, sklejka, itp.), nogi drewniane tarczy, a nawet metalowe elementy mocujące nogi do tarczy. Na podstawie przeprowadzonych badań wykazano, że zakazane do stosowania na pośrednich liniach celów tarcze metalowe mogą powodować znaczne odchylenia toru lotu pocisku po przebiciu oraz niebezpieczne rykoszety. Z tego powodu tarcze metalowe ustawiane są wyłącznie na ostatniej linii celów przed kulochwytem głównym, gdzie parametry techniczno-balistyczne kulochwytu zapewniają wychwycenie ewentualnych rykoszetów. Stwierdzono, że stosowane na pośrednich liniach celów tarcze kontaktowe, posiadające nogi drewniane, mogą powodować zmiany trajektorii pocisków porównywalne lub nawet większe niż w przypadku zakazanych tarcz metalowych. Z tego powodu wskazane jest stworzenie ram prawnych dla kontroli balistycznej materiałów, z których wykonywane są tarcze przeznaczone do stosowania na strzelnicach garnizonowych.

The intensive development of sport shooting and the significant increase in the number of people using sport and recreational shooting ranges also increases the risk of hearing damage to shooters, due to exposure to impulse noise from the shots of firearms. This article discusses the methodology for assessing shooters’ exposure to noise and identifies and extensively discusses possible ways to minimise this exposure. It then describes a research experiment carried out to measure and calculate the effectiveness of noise reduction by means of acoustic silencers when shooting with typical weapons in the most popular sporting and hunting calibres. The experiment also included firing tests with subsonic ammunition. On this basis, conclusions were drawn regarding the possibility of reducing impulse noise during shooting and the possibility of eliminating the risk of hearing damage.
