“…Also previous studies [14][15][16] focus on planning the maneuvers of autonomous vehicles on roads and avoiding collisions. A more detailed assessment, depending on the speed of road vehicles, based on the analysis of speed of movement, width, angle, and side inclination of roads was described in the work by Bekesiene et al 17 Previous studies [18][19][20] further cover modeling and simulation of movements of forces and equipment on the battlefields of the 21st century, focusing on an urbanized area and the degree of autonomy of unmanned systems. These articles further describe possible uses of autonomous systems on battlefields, including specification of the degree of autonomy and human control in task assignment, specifically in controlling unmanned systems.…”

The article describes the possibilities of using the Maneuver Control System CZ (MCS CZ) in creating a multiple maneuver of a group of cooperating units. It is a tactical information system designed to support the decision-making of commanders in order to effectively deploy their units on the battlefield. The system evaluates the geographical and hydrometeorological battlefield influences as well as the enemy’s situation to calculate the maneuver axes of a unit composed of up to three teams with the same goal. To verify the calculations of mathematical-algorithmic models of the system, two measurements were performed on model situations. In the first of them, a group of three unmanned systems carried out an attack on an identified delivery system of weapons of mass destruction. The second model situation included a hasty attack by three infantry squads on anti-aircraft equipment. In both cases, the resulting group of maneuvers used the fastest and safe axes of advance, spatially synchronized according to tactical principles. In both cases, the enemy’s weapon systems were quickly attacked and destroyed immediately after their identification from three directions. The commander’s decision-making process was largely replaced by the MCS CZ calculations in model situations, which significantly shortened its duration.

“…Levels of hair steroid hormones: cortisol, cortisone, and the dehydroepiandrosterone steroid hormone (DHEA); Negative binomial regression was used to overcome a limiting property of the Poisson distribution, where λ equals both the mean and variance [47]. The negative binomial regression model is based on the distribution of a Poisson-gamma mixture distribution and allows the modeling of Poisson heterogeneity using a gamma distribution [48]. In this study, the negative binomial regression model was built using the same input variables as in the Poisson regression model.…”

Compulsory basic military training is characterized not only by being challenging but also by being stressful. Assuming a high frequency of perceived stress events as a negative outcome of training, this article provides evidence on how the perceived frequency of stressful situations is affected by three types of factors: (i) biological stress response variables measured by hair steroid hormone levels, (ii) personality traits measured using the Big Five personality test, and (iii) group cohesion measures in military squads. A total of 112 conscripts in 11 squads participated in the research at the beginning (T1), in the middle (T2), and at the end (T3) of compulsory basic military training. Hair steroid hormone levels (cortisol, cortisone, and dehydroepiandrosterone (DHEA)) levels were measured by liquid mass spectrometry; other data were collected using self-report questionnaires. The results of the Poisson regression analysis indicated that hair steroid hormone cortisol had a statistically significantly impact and could increase the perceived frequency of stressful situations by up to 1.317 (e0.275, T2) times. The concentrations of other hormones (cortisone = 1.157, e0.146, T3 and DHEA = 1.020, e0.020, T3) also had a statistically significant effect. Other factors had a decreasing effect on the frequency. Extraversion was significant with an effect of 0.907 (e−0.098, T2) and 0.847 (e−0.166, T3), while task cohesion had an effect of 0.946 (e−0.056) and norm cohesion of 0.954 (e−0.047). The research indicates that the three groups of factors affect the perceived frequency of stressful situations during compulsory basic military training, but their impacts are considerably different.
