Maintenance and repair (M&R) of military equipment are crucial for operational readiness. The article highlights challenges faced by military forces, particularly in the US, with significant equipment non-operable due to inefficient M&R. It emphasizes modernizing M&R through Predictive Maintenance (PM) and 3D Printing (AM). PM employs AI and data analytics for real-time monitoring and foreseeing malfunctions, signifying a strategic shift in M&R. AM significantly curtails downtime by enabling on-demand spare parts production, presenting a solution to traditional military M&R challenges. The article also underscores the economic advantages and potential for operational efficiency improvements through these technologies. However, it points out hurdles in implementing PM and AM, including high initial costs, lack of trained personnel, and the threat of counterfeit production in AM.

Military spending is a widely discussed topic, especially in the current geopolitical landscape. Expenditures on "equipment" play a pivotal role in total defense spending.. However, the nature of the equipment expenditures is cumulative. Thus, when trying to estimate the capability of a state we should consider a longer period, not just one year. The aim of this article is, therefore, to offer (i) an exploratory analysis of the cumulative equipment expenditures of NATO countries between 2014-2023 and (ii) to verify - by using OLS multivariate regression - the extent to which the GDP per capita primarily drives these expenditures (adjusted per soldier), the share of defense spending from the GDP, or by the fraction of defense spending that goes specifically to equipment. The results show that the GDP per capita is by far the most powerful predictor.

The article presents more than ten years of experience in testing the abilities of pilots during flight control on flight simulators. A hypothesis is stated about the possibilities of finding common features in flight control, the basic mathematical apparatus for evaluation is presented, the flight simulators used and, of course, the achieved results are presented. 110 pilots have already been tested and a total of 2360 missions - test flights - have been simulated. Subsequent mathematical analysis provided approximately 40,000 results suitable for further statistical processing. This amount of data obtained from realistically simulated flights provides a prerequisite for defining applicable conclusions to the proposed mortgages. For the needs of subsequent certification, a proposal for the pile measurement methodology was also prepared, which summarizes both the theoretical approach to pile testing and the procedure for carrying out tests on individual simulators. Part of the proposed methodology includes an overview of the software created to facilitate the recording of data from individual missions, as well as software for own analysis of the measured data from the missions.

The selection of optimal weapon systems is crucial for national defense. Traditional empirical methods struggle to address the complexities of modern warfare. This article explores the potential of constructive simulation for informed decision-making in this domain. Simulating tactical operations with complex variables, such as terrain, enemy actions, and system interoperability, provides valuable insights into weapon effectiveness. This enables the optimization of acquisitions in line with strategic goals. Design simulation allows for the exploration of factors difficult to test comparison of armament configurations, analysis of enemy tactics, and optimization of unit composition and deployment, saving costs and time. Simulation enables the safe exploration of even high-risk scenarios.

The article deals with the issue of the cognitive pyramid and the possible use of intelligence analysis in the context of gaining the understanding and wisdom of users of information using this pyramid. The cognitive pyramid is used to define the terms date, information, knowledge, understanding and wisdom that make up the various levels of the pyramid. The paper attempts to discuss concepts in different models of the pyramid. It briefly describes intelligence in the context of the use of intelligence by means of a cognitive pyramid. Intelligence is a special kind of knowledge. This article also seeks to explore how intelligence creation can be explained using a cognitive analytical pyramid model.

The article deals with the artillery manual gunnery in accordance with the modernization of the czech artillery. The article describes the results of research aimed at innovating manual (alternative) methods of determining the firing data so that they are applicable on the contemporary battlefield and are compatible with the nature of the data used by artillery within the NATO. The issue of the article is aimed primarily at determining the firing data by the use of meteorological techniques, while presenting the outputs of a comparative analysis of procedures used in the czech artillery with the procedures applied by the US army. The main contribution of the article is a critical evaluation of the approaches of both armies and a proposal for innovation of existing procedures so that the most beneficial requirements are applied and negatives are eliminated.

This article describes the basic terms used in prognostics (future studies, forecasting the future, prognosis, prediction, expert) and introduces selected prognostic methods and techniques which could be applied in security area (brainstorming, focus group, trend extrapolation, Delphi method, scenarios etc.). The basic classifications and prognosis typologies are mentioned as well. Particular phases of prognosis making are described too. For the Czech security community the prognosis making has an important potential whose outcomes (of particular surveys) should be manifest in following years. This text has only tried to outline selected methods and techniques for their potential application.

The general trend of weight gain, decreasing physical fitness and health complications in the general population is also reflected in the recruitment of new candidates. Their physical readiness is expected to be high. The aim of this study was to verify whether or not the physical condition of the soldiers entering the army during the 2000-2017 test of physical fitness actually deteriorated or not. The results for the assessed period in the monitored parameters indicate that some components of physical fitness are copying the general trend and showing a slight deterioration. Yet, in general, it can not be said that the fitness of new soldiers is declining, as some of its components show a slight increase.

The article deals with economical aspects of operation of the military vehicles designated for the transport of persons in the competence of the defence department. In the beginning of the article basic concepts are defined, types of vehicles, and current structure of fleet of the sector. In addition, all passenger vehicles and buses exceeds the national average age in 2015. A more detailed analysis showed that the MoD makes the procurement of new vehicles in cost-effective way, and the structure of these purchases began to predominate significantly cars with diesel engines in the last ten years. However, the lack of monitoring of the total costs of operating vehicle use all cars unevenly, and fleet renewal is realized in low volumes. Although the data in the article are reported to and including 2015, evaluated the development and evolution of this trend persists until today.

This article aims at building a bridge upon a gap, which separates academic sphere and intelligence community in the issue of predictive methodology. The author tries to accomplish this objective by presenting intelligence predictive methods based on open-source literature research. First, the question of uncertainty and probability in prediction is introduced (Cynefin template). Then follows basic introduction to predictive methods in civil and military intelligences, so that the reader might grasp the fundamentals of early warning systems. The academics and above all journalists should know the risks and perils in forming intelligence forecasts, estimates, foresight and warning scenarios, e.g. the so-called Black Swan scenario, the author explains potentials failures of the Delphi method. This study ought to be regarded as an introductory to predictive intelligence concurrently done by governmental agencies for purposes of national security and defence.

The main goal of this article is to depict the issue of intelligence information sharing within the so called principle "need to share" and highlight the differences of this current trend, which was to replace the "need to know" principle. The first chapter in reference to current global threats depicts the extent of the present national and international interrest in the intelligence field which is followed by the issue of "need to share" principle. The aim of the following chapter is briefly analyse the sfaring of intelligence information within NATO and the EU. This chapter also includes the possible sharing of SIGINT information obtained by national tactical element embedded in Task force during current day operations. The final part evaluates the intelligence information sharing and outlines certain prediction of future development in this field.

The article presents six more or less structured analytical methods that are or could be employed in intelligence analysis. This type of analysis, one part of the intelligence cycle, is understood as "the process of evaluating data for reliability, validity, and relevance; integrating and analysing it; converting the product of this effort into a meaningful whole, which includes assessment of events and implications of the information collected". The set of presented methods includes: link analysis, opportunity analysis, analogy, linchpin analysis, analysis of competing hypothesis and alternative scenarios. The study doesn't stop with presenting those methods; it also explains which type of reasoning (inductive, deductive or abductive) is used when working with each particular method. In broad terms, the article tries to shed light on intelligence analysis and its specifics. The reader should obtain better understanding their usefulness in the daily work of intelligence analyst.

The authoress surveys recent research into how people acquire languages and considers its relevance for language teaching. She describes the most important studies and ideas about language acquisition. The method mentioned above is element. If we compare it with other language skills, i.e. reading, writing, speaking, it is above all listening that is used most. But to acquire sufficient proficiency, learners must cover a long way. Language teaches should do it for students the most pleasant as possible. Listening in language classrooms is being assessed, according to levels of students' understanding contents. The authoress familiarizes readers with several ways of teaching by principles that are in fact interactive approaches to learning foreign languages. We may use forecasts, news, listen radios, watch films in target language, be in touch with native speakers. It is reccomended to write down new word power, according to set context.
