The data on the initial testing stage of clothing, shoes, and combat equipment in the Research Testing Center of Military Medicine and Military Medical Equipmentthe replacement of the Research Sanitary Institute of the Red Army. A brief historical information about the hygienic research of materials for clothing and clothing itself in Russia was provided. The fundamental study basis of clothing and footwear conducted by F.G. Krotkov were the works of many of his predecessors scientists of the Military Medical Academy and heads of the oldest hygiene department in Russia (Professors A.P. Dobroslavin, V.A. Levashev, P.E. Kalmykov, N.F. Galanin et al.). Additionally, three research directions were formed as the clothing doctrine gradually developed. The first was concerned about the materials research for clothing creation, second was the study of the created clothing with the help of devices in the laboratory, and the third was the study of the functional state of the human body in the evaluated clothes. The role of F.G. Krotkothe first head of the hygienic department of the said institute in the formation of requirements for clothing and footwear of military personnel. F.G. Krotkov conducted a hygienic assessment of hats adopted in the Red Army in 1931; in 1932, he examined the fabrics of military uniforms; in 1935, hygienic requirements for the mountain troops uniforms were developed with his direct participation; and in 1936 ski units. A hygienic assessment of the uniform of military personnel was carried out in the shortest possible time in 1941 under his leadership. The hygienic requirements for clothing and footwear were formulated by F.G. Krotkov based on the results of these experimental studies. The relevance of the developed requirements for clothing and footwear in the present time is noted.

The article discusses modern approaches to anthropometric research. The article presents the current trends in the physical development of young people of military age in the context of epochal variability (secular trend). It has been established that the normative documents regulating anthropometric research need significant processing in accordance with the realities of the time. At the same time, new technologies for studying anthropometric indicators have appeared in recent years, which, with the help of digital visualization, make it possible to perform not only an assessment of linear and projected body sizes in a short time, but also to build computer models of the human body. To solve these problems, it is proposed to use the Bodiscanner 3D Bio Kinect device and its subsequent adaptation for conducting anthropometric studies in the interests of the Ministry of Defense of the Russian Federation.

Currently, as part of combat equipment, body armor is the main tool designed for individual protection of a persons torso from bullets, shrapnel and steel arms. Since March 1, 2019, GOST 34286-2017 has been introduced as a national standard of the Russian Federation, in which one of the assessed indicators of the resistance of armored clothing to the effects of means of destruction is the indicator of the reserve effect of the striking element when the protective structure is not penetrated, which should not exceed the value taken as the maximum permissible in the prescribed manner. In this case, the pre-armor effect of a striking element in case of non-penetration of the protective structure is assessed only after the completion of the development of a sample of armored clothing by the corresponding accredited organization. The existing methods for determining the permissibility of the reserve impact indicator when the protective structure is not penetrated can in principle be divided into medical, biological and technical, and technical. In the Russian Federation, the method using large laboratory animals, pigs weighing 8090 kg, is mainly used to determine the level of the reserve impact in terms of the severity of the reserve contusion injury. While in NATO countries, human corpses, individual tissues and organs, as well as parts of carcasses of large animals are used to determine the same parameter. However, at present, both in our country and abroad, there is no single methodological approach to assessing the impact of armor when testing protective products. As a result of targeted research, it is necessary to scientifically substantiate the principles of modeling this effect when the body armor is not penetrated with the subsequent processing of standard methods of state testing of body armor. The tests must be based on a method that allows obtaining parameters expressed in digital values and correlated with the results of experiments on biological objects. It is this numerical parameter that should be taken as a criterion for assessing the permissibility of the level of shock impact when testing promising personal body armor (bibliography: 21 refs).

The paper presents the intermediate results of an experimental study of three samples of chitosan-based local hemostatic agent in a model of intense intra-abdominal bleeding in an average-sized experimental animal (a Soviet Chinchilla rabbit) with a standard wound on the parenchymal organ (liver) in combination with external compression of the abdominal area to achieve hemostasis in the acute phase of the experiment. At the first stage, nine experimental groups and one control group, with three biological objects each, were involved (n = 30). The composition and properties of laboratory preparations of hemostatics were different from the concentration of the main component. To select the optimal sample of a local hemostatic agent with the least local irritant effect on the organs and structures of the abdominal cavity, three experimental groups with three animals each were formed at the second stage, without modeling blood loss (n = 9) with follow-up from 24 to 72 h. The studied drugs have high hemostatic activity in the model of intense intra-abdominal bleeding with follow-up periods from several hours to 3 days. Moreover, intraperitoneal administration of hemostatic agent samples does not lead to a pronounced local irritant effect. However, during the first 180 min of the experiment, only one fatal outcome was recorded in a group of animals with 15% chitosan in the studied drug because of a technical error in modeling the source of bleeding. External compression of the abdominal area demonstrated its effectiveness as an auxiliary technique for temporary control of the intra-abdominal source of bleeding in the experimental model. The objectification of the obtained results was achieved through a control sectional study and laboratory screening of peripheral blood indicators of experimental animals at different stages of the experiment. To further evaluate the hemostatic activity of chitosan-based drugs, creating an experimental model using a large experimental animal is necessary.
