Description: The nature of the physical loads experienced by soldiers of various armies in the process of making foot marches, from antiquity to the Second World War, is analyzed. It is shown that even after full motorization of the ground forces, servicemen undergo heavy physical loads during both the exercises and the fulfillment of the combat mission, and the crews of armoured vehicles operate under extreme conditions. As a result of the impact of excessive loads, psychophysiological and neuropsychic disorders can develop in members of extreme professions. To solve this problem and reduce the negative consequences of the above factors, a set of measures, including pharmacological nature ones, should be carried out. The method of choosing the optimal type of adaptogen providing high operability of operators is suggested, provided that unfavorable external factors influence them. The methodology includes the consistent application of methods of cluster analysis, pattern recognition, rank correlation and multicriteria optimization. The application of cluster analysis makes it possible to group the available research results into homogeneous groups. To classify the results of testing new adaptogens, a polynomial decision rule with a relay right-hand side is used. The choice of the optimal adaptogen is carried out by means of a multicriterion optimization procedure using a linear convolution of the criteria. The approach adopted in the work, by changing the weights of particular criteria, allows us to choose the type of adaptogen taking into account the special features of the task assigned to the combat vehicle crew.
