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.

An important part of NATO's deterrence and defence role is its military presence in the eastern part of the Alliance's territory, represented by the Bucharest Nine (B9). The ability of this group to fulfil its strategic mission depends on the condition of the military equipment at its disposal. The number of pieces of military equipment and their combat capability are determined by the investment in military equipment. In the context of the pledge to spend at least 20 % of total defence expenditure on military equipment, it appears that between 2004 and 2022 there is a steep increase of defence investment gap, followed by a partial absorption of the investment gap after 2014. The investment gap is reflected in the volume and condition of military equipment. Rising spending in recent years is positively reflected in the increasing volume of acquisitions for new military equipment in all B9 countries. However, due to the delay, these investments are and will only be reflected in defence capabilities in the future.

The paper deals with the Czech artillery application equipment for enabling more efficient execution of classical ways of some measures in case of malfunction of the field artillery automated fire control system. The first part of the paper includes an analysis of Czech artillery current software and the introduction of two developed software. This two developed software are under finishing works and they should partly eliminate the poor Czech artillery software equipment. On the basis of the synthesis of author's experiences followed from the development of two new programs PVNPG-14 and ArtyCalc there are defined key principles in the paper, that should be applied in the future development of new software for the Czech artillery.

This article focuses on the identification of key factors of material resources in the field of equipment, armaments and military vehicles within the Czech state needed for effective mobilization. The primary goal is to answer the question of whether the Army of the Czech Republic still has adequate supplies of these key resources and whether it has the ability to increase these resources in crisis situations without significant dependence on foreign imports. The above analysis revealed mostly sufficient stocks, but at the same time significant limitations were identified in some categories, especially in their technical and moral quality (obsolescence, respectively), especially in most types of military vehicles. The issue of dependence on foreign imports concerning raw materials then changes considerably, from the minimum (combat dress) to the almost maximum (ballistic helmet) level.

This study explores the main challenges faced by leaders within the multinational military operations process. Based on the aspects addressed in the literature review, the questionnaire survey method will be applied to a representative sample of military personnel who had participated in various multinational activities, as tactical leaders. The findings reveal that the most significant challenges perceived by leaders include linguistic barriers, command and control (C2) issues, and differences in training, endowment, and doctrine, with planning identified as the most challenging operational phase. Statistical analysis further indicates that experienced leaders perceive these challenges more acutely, and the study outlines key solutions proposed by respondents, such as developing language skills, enhancing interoperability, and fostering adaptability as essential traits for overcoming difficulties in multinational  military operations.

The article holistically analyses current strategies for the use and development of nuclear forces of the USA and Russia and analytically reflects their mutual doctrinal interactions. It deals with the conditions under which the U.S. and Russia may opt for using their nuclear weapons and reflects also related issues of modernization and development of their actual nuclear forces. The author argues that both superpowers did not manage to abandon the Cold War logic or avoid erroneous, distorted or exaggerated assumptions about the intentions of the other side. The text concludes with a summary of possible changes and adaptations of the American nuclear strategy under the Biden administration as part of the assumed strategy update expected for 2022.

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.

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 work deals with the issue of engineer information, which is necessary for the planning of water crossing, and which can facilitate and speed up the proces of operation planning with the assistance of the staff members of engineer specialization. At present (2019) there is no application software development of engineer support tasks (hereinafter APV ŽEN) within the engineer command and control subsystem AČR, which would take into account the problem of water crossing by troops. The aim of the article is: to analyze the gathering of engineer information for water crossing and to describe it on a specific example of the Morava river, to identify the possibilities of water crossing by forces of AČR, to propose a map base for APV ŽEN, which will be supplemented by engineer information from Povodí s.p. and Motorway and Highway Directorate (hereinafter ŘSD) and to define measures that will support the availability of engineer information in water crossing.

The guarantee of national defense and the fulfillment of commitments to Allies is highly dependent on its financial source security. The economic recession, which began in 2008 in the USA, negatively affected public budgets. This recession was one of the causes of the reduction of planned defense spendings in the Czech Republic. This reduction caused the postponement of acquisitions, which were to be implemented both with regard to commitments to coalition partners and with regard to maintaining their own defense capabilities. Nowadays, current internal debt is still increasing due to neglecting inflation of military equipment, which is higher than inflation of ordinary goods. Currently, the defense ability is also affected by the pandemic of Covid-19, which caused a slowdown in GDP growth and public spending growth. For this reason, it has been several times postponed the commitment to achieve a rate of 2% of military expenditure of GDP by 2024 and the current plan to achieve it in 2027 is also endangered.

The assessment of force ratios and battle casualties is a crucial aspect of the military decision-making process. This article evaluates three different tools used by the Army of the Czech Republic at the tactical level: a calculator based on Lanchester's laws, a module within the Battle Information System, and a constructive simulation system. The results indicate that while all tools produce similar outputs, the constructive simulation system offers more accurate estimates of combat losses for both equipment and personnel. Additionally, this system enhances the ability of commanders and staff to adapt to changing scenarios during planning. The primary conclusion is that the constructive simulation system provides a practical and flexible solution for supporting the military decision-making process at the brigade and battalion levels.

The article describes attributes will influence character of modern warfighting and presents the basic approach to prepare commanders and leaders of "new generation". The operational environment describes determinants and characteristic of today's and future warfighting. Technological development as booster, change the tools and the procedures but not the nature of war. Level of training and leadership quality multiplies combat power. The key findings and recommendations support fundamental idea of ability to lead and manage hybrid systems in volatile multi-dimensional environment, using various tools and sources, appropriate to specific environment and specific tactical level mission, stressed in last chapter as result of this study. The article´s aim is support discussion, which directions we will adapt currently ongoing or newly creating study programs, preparing new generation of warriors - leaders.

The article deals with the formation of artillery in the Czechoslovak legions in Russia. Using information drawn from contemporary sources and books from the 1930s, it presents the basic milestones that were at the birth of this important part of the Czechoslovak legions.

This article presents the first systematic analysis of cognitive resilience education within the Czech Ministry of Defence, which is growing in importance in the context of contemporary hybrid threats. Through methodological triangulation (document analysis, questionnaires, interviews), the research maps the coverage of relevant topics across all levels of formal military education. The SWOT analysis reveals both existing foundations for cognitive resilience development and the absence of a systematic approach to this issue. The results highlight three main challenges for transforming the educational system: systematisation of the approach, personnel resources, and infrastructure modernisation. The study establishes an empirical basis for strategic recommendations to strengthen military personnel resilience against information and psychological operations.

The language training within the Ministry of Defence [MoD] of the Czech Republic is primarily focused on English. However, in accordance with the Concept of Personnel Training for the Needs of the MoD, the MoD provides language training in other foreign languages as well. The language teaching is the responsibility of the Language Centre of the University of Defence Brno [CJV UO] and includes English, French, German and Russian. The aim of this article is to compare the activities of the CJV UO with similar language centres in the defence departments of Germany, Austria and France and to present the teaching of French, German and Russian within the MoD through examples of good practice. In the context of the current geopolitical situation, the teaching of French, German and Russian becomes more important, and the CJV UO responds flexibly to the demands of the MoD regarding the provision of the teaching of these languages including professional language and electronic teaching support.

The civil war in Myanmar has been going on for more than seven decades. After the military coup in February 2021, it has undergone significant structural changes and gained new momentum. The causes of the conflict lie in the inability of different ethnic and political groups to find a way to coexist within a single state entity and the autonomisation of the military. The main actors in the war in Myanmar today are the military junta and its supporters, the democratic opposition and ethnic organisations. After the coup, the strength of the resistance movement and its operational capabilities are growing. However, this growth has its limits, given the continued disunity of opposition forces, the technical superiority of the Myanmar army and the strengthening of its numbers through compulsory conscription.

The article deals with the possibility of using simulation technologies in the training of students of the University of Defence in tactical training and seeks to answer the question whether the use of these means brings demonstrable effectiveness by means of an experiment. First-year students in a Field Training course were randomly divided into 42 sections of approximately equal numbers and then assigned to 3 categories based on their use of live and virtual simulation. All groups were assigned points for a specific tactical activity during the final exercise. The total scores of all groups were subjected to a subsequent statistical investigation using a one-factor analysis of variance on the data to examine whether there were statistically significant differences between the groups. Although students' use of modern simulation technology had a perceived positive effect on improving the quality of training, there was no evidence of statistically significant differences between the groups studied using statistical methods. However, the results of the experiment do show to some extent that some differences do exist between the groups and therefore leaves some opportunity to conduct similar, or more extensive research, in an effort to promote the attractiveness of the training process to military school students.

The article deals with the evaluation of current possibilities of medical support capabilities in the area of Chemical, Biological, Radiological and Nuclear Defence. The evaluation of national strategic documents shows that the area of providing care in the event of chemical and biological hazards is significantly more developed than in the area of radiation, while the security threats associated with radiation are constantly growing. Analysis of NATO standardization documents in the field of medical support and relevant Czech doctrinal documents was carried out, based on which the diagnostics and triage of irradiated persons, called biological dosimetry, was identified as a potential capability. Using the capability planning methodology and based on the evaluation of the functional areas, a conceptual approach to the development of biological dosimetry capabilities was defined. The presented recommendations also include a proposal for the organizational structure of the Czech Armed Forces biodosimetric network.

The article deals with the possibilities of protecting the outer perimeter of static military facilities using ground-based unmanned systems that can complement the already existing protective elements. The conclusions reached and theoretical assumptions were experimentally verified in the field during the protection of a small base, using UGS Taros Furbo and Tactical Decision Support System calculations. The protection routes calculated by the system were then practically implemented by dismounted patrols and autonomous UGS Taros Furbo, focusing on terrain traversability and time of overcoming. The main objective of the paper is to present to the military public the current possibilities of deploying UGS Taros Furbo in the protection of static military facilities such as command posts or bases. Their use can significantly reduce the requirements for the deployment of dismounted patrols to protect the outer perimeter.

The article follows the author's comparative analysis of American and Russian nuclear doctrines and armaments from the fall of 2021. It presents the current nuclear strategy of the United States of America based on a content analysis of three specific areas of the updated version of the Nuclear Posture Review. Applying interpretive analysis and a rich secondary sources apparatus, the author also reflects on his 2021-formulated assumptions and expectations about the further development of American nuclear strategy under President Joe Biden. The author analyzes the influence of the presidential administration's ideological and political ambitions together with the decisive geopolitical events of 2022 and concludes that mainly due to the second factor, the current shape of American nuclear strategy has not undergone any revolutionary changes and continues to maintain a long-standing continuity and consensus about its basic principles.

The article deals with the basic characteristics and tactical-technical requirements for the tactical unmanned aerial system (TUAS), which is planned to be implemented in the Czech Armed Forces in the upcoming years. Based on the results of the comparison of the Czech Armed Forces requirements with the parameters corresponding to the TUAS, the Hermes 900 and Heron systems of Israeli production appear to be the most suitable variants. Both aircrafts can represent a comprehensive solution in this area. They both have a long tradition of production, research and development and of course, they both meet the requirements for TUAS within NATO and the European traffic operations accreditation. However, the decisive selection parameter, apart from security risks and compatibility, is also the purchase price. The main goal of the article is to bring a view of the issue from a broader context and to find a possible way-out together with an evaluation of the advantages and disadvantages of each of the proposed variants.

IoT devices (sensors, drones, cameras) are gaining more and more emphasis on military operations. The application of IoT elements in the military environment increases situational awareness and supports the acquisition and maintenance of information superiority. The information they provide about the enemy, the area of operations, and the location and status of our soldiers and assets can contribute to the successful execution of operations at the tactical, operational and strategic levels. However, they can also pose serious threats if their vulnerabilities allow the data they collected to leak or they provide access to the info-communication networks used for the enemy. In this article, the author examined the vulnerabilities of these IoT devices using keyword analysis. After drawing conclusions from the analysis of the relevant literature, he compared the results with the general-purpose IoT threats and attacks typical of today, like distributed denial of service attacks, security, software, security and privacy issues.

The paper evaluates the level of cooperation between the Ministry of Defence and the NATO Support and Procurement Agency (NSPA) in the field of procurement of military equipment. In the practical part, the results of the research on the level of participation of Czech-based suppliers in NSPA activities between 2018 and 2022 are presented. Pareto analysis comparing the participation of the Czech and international companies in contracts implemented by NSPA in terms of their subject, quantity and financial value is used. Qualitative case studies from three different areas illustrate in which NSPA projects the Czech Republic has already been involved in and which benefits and risks are associated with this cooperation for the MoD. Positives and drawbacks in the process of acquiring military equipment in-house and opportunities and threats that may arise from the acquisition of military equipment through the NSPA are summarised in the form of the SWOT analysis. Finally, recommendations are presented on how to improve the cooperation between the MoD and the NSPA in the field of acquisition.

The aim of the paper is to determine the extent of the use of strategic and decision-making analysis methods and the specifics and barriers of their practical application in the process of creating conceptual documents in the Ministry of Defense of the Czech Republic. In the qualitative research, a semi-structured questionnaire was created for the purpose of data collection and submitted to eighteen creators of the department's conceptual documents. The obtained data were evaluated by open coding according to the grounded theory, one of the methods of systematizing qualitative data. The results show that the methods are used, but informally or in a modified form - adapted to the specifics of the department. Barriers to the use of methods, are primarily the varying level of competence of the creators, the inappropriateness of certain methods for certain types of documents, time pressure or the preference for an intuitive approach. The ideal strategy seems to be a combination of the intuitive and rational approach.

The article deals with the some legal aspects of Western military aid to Ukraine. The first part briefly analyzes the Russian Federation's attack on Ukraine from a "just war" perspective. The following part is devoted to individual perspectives of different branches of international law on military aid to Ukraine - the law of neutrality, ius ad bellum, ius in bello, issues of co-belligerency and state responsibility for complicity in internationally illegal actions. The conclusion summarizes the findings and gives an answer to the question why Western aid to Ukraine mostly does not violate the norms of international law.

Infantry company urban operations training experience shows that effective training requires interaction of doctrine with equipment and structure of units. NATO standards must be further developed at the national level to match the technology and organization of own units. Training requires elaboration of training manuals that contain specific tactical exercises for standardized training facilities. Experienced training instructors should focus on the preparation of organic units. Transferring experience from instructors directly to organic units is more efficient than preparing individuals in professional courses.

The article addresses the issue of the emergence of new technologies and their impact on the capabilities of the Czech Armed Forces (CAF). A summary of the recommendations is presented. In particular, there is a need for a conceptual approach to the integration of new systems in order to avoid spontaneous purchasing, which could be very logistically demanding. The very rapid development in the field of unmanned autonomous systems using elements of artificial intelligence offers opportunities to use them in support of the tasks of CAF. Due to the breadth of this issue, the scope is limited to the area of the Special Forces, which introduce these new sophisticated means into use throughout the Ministry of Defence of the Czech Republic.

The article deals with the preparation of the Active Reserve of Czech Armed Forces, territorial forces in detail. It compares them to the equivalent of the active reserves of the Polish army, namely the Territorial Defense troops. A comparison of the development and preparation of these forces points to the necessity of solving or updating the system of calling up reserves of the Czech Armed Forces, their training, arming and equipping.
