The fundamental purpose of the nuclear forces that remain is political: to preserve peace and prevent coercion. The Alliance has taken far-reaching steps to adapt its overall policy and defence posture to the new security environment. NATO?s nuclear strategy and force posture were among the first areas to be reviewed. The Alliance?s 1999 Strategic Concept set forth the essential principles for the role and characteristics of NATO?s Nuclear Forces. This article provides an account of the most significant changes to NATO?s nuclear policy. As a first major step of relaxation, the readiness posture of dual-capable aircraft was greatly reduced, in 2002, the readiness requirements for these aircraft were further reduced and are now being measured in months. The author also writes about problems discussed at informal meeting of NATO defence ministers at Taormina, Italy, 2006.

The article deals with selected international treaties, current agreements and international cooperation initiatives in the field of non-proliferation of nuclear and chemical weapons, in which the Czech Republic is represented through specific bodies or ministries. There is also a general description of the view and the specific military approach. The involvement of the MoD and the Czech Armed Forces in NATO structures enables to influence the strategic decision-making in the area of CBRN and thus support the current trends concerning forensic analysis, sampling of CBRN samples and response to new trends in the field of WMD elimination.

This paper examines the role of strategic communication in military operations, with a focus on its impact during the first year of the Russian-Ukrainian war. Using a process-tracing methodology, the study explores whether Ukrainian strategic communication was decisive in resisting Russian attacks. Our findings indicate that strategic communication functioned as a central component of Ukraine’s defence. Effective messaging mobilized broad support from diverse actors, including state entities with no regional stakes and non-state contributors such as civilians, volunteer fighters, and organizations, driven by motivations beyond self-interest. Ukraine’s resilience stemmed not from a deceptive Russian strategy (i.e., a lack of genuine intent to engage in a full-scale war), but from its bold counter-offensive, bolstered by international aid - support amplified and sustained by the strategic communication efforts that shaped global perceptions and secured critical assistance.

This concept has been preparing since the early 2009. In short, the North Atlantic Treaty Organisation must be increasingly prepared to intervene far beyond its borders. In the coming decade, NATO will have four central inter-related military missions. The first requirement is to "deter, prevent and defend" against aggression, so as to ensure the political independence and territorial integrity of NATO member states. The report insists on the need to send out military missions beyond the treaty area "when required to prevent an attack on the treaty area or to protect the legal rights and other vital interests of Alliance members". Any expeditionary mission must be based on the principles of the UN charter. Another key item is to cooperate better with those partners, and others worldwide, in order to tackle the new threats posed by cyber attacks, piracy, arms proliferation and energy supply insecurity and climate change. However, in order to achieve the new goals, NATO "must halt the precipitous decline in national defence spending", and to introduce reforms to make spending more efficient.

All-inclusive attitude of NATO forces assumes that conflict can't be solved only by military means. This shift from purely soldierly level to political brought around numbers of Alliance activities at Strategical and Operational Commands. The common denominator was the philosophy of complex approach in operational thinking, planning, and implementing NATO activities. As a result the operational SACEUR's directive GOP was substituted by its revised successor-the so-called Comprehensive Operations Planning Directive (COPD). It is going to be introduced in 2011 and will influence groups and military persons at all levels of warfare, dealing with operational planning and operational art for art's sake. The article familiarizes readers with this directive (COPD) as a tool for comprehensive approach to operations. The COPD offers more deliberate and inclusive planning procedures that allow for both military and non-military actors broader understanding of operational environment and better cooperation in their common effort.

The article focuses on information and psychological operations as a challenge for the security and defence establishments of NATO member states. A conceptualisation of the terms 'information operations' and 'psychological operations' is discussed in the contexts of reshaping the war-and-peace dichotomy, and of resilience and deterrence. It is suggested that these terms suffer from a normative approach to the paradigm of war and peace, and to the use of non-military means. This may lead to the greater vulnerability of security and defence systems in confrontation with an adversary. Also, special attention is paid to the vulnerabilities of security and armed forces, being overlooked in concepts of resilience.

The NATO's New Strategic Concept is only starting point to open discussion on a wide range of security problems. At the beginning there is a description of Czech home politics, attitudes of Czech political parties toward NATO alliance. The author explores the history of NATO's identity crisis. In recent years, different security optics of the members splintered NATO. The US wants an expeditionary alliance with a global reach, the Western Europeans hold to a vision of a regional club of liberal democracies, the Central Europeans have a wish so that Washington would stand by them when they will find themselves pressured by Russia. NATO is divided on how to reform its decision-making processes and how to fund and resource its home and away missions. In Afghanistan, the Alliance faces the most difficult operational challenge to date, with a real possibility of strategic failure. The overarching problem is how to define the core business of NATO: cyber defence, energy security, WMD proliferation, stability and reconstruction missions, out-of-area missions, territorial security, enlargement, partnership-building. The discussion over the New Strategic Concept needs to reorder the question how to define NATO's appropriate roles and go from there.

Recent developments in security environment in the last two years re-opened crucial European debates such as the reform of the NATO architecture to address resurgent Russia to the East and as finding common European solution to migratory pressures that test both national capabilities and European solidarity. Even through the Visegrád countries do not always share common interests, the V4 manifests that it can play indispensable role in reaction to these developments. However, V4 still lacks actually proactive regional approach that would accommodate polish interests in order to keep informal leader Poland invested in this cooperation format. Polish elections mean one more challenging test for the V4 to coordinate positions before the crucial NATO Warsaw summit. Should this endeavor be unsuccessful, Poland could look to other formats that mirror its interests and threat perception more closely meaning that V4 would take a back seat with regard to NATO agenda. The task for the Czech V4 presidency is to produce practical results in ongoing ambitious project in defence cooperation so that is demonstrates the cooperation's 'added value.'

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 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.

This article presents a formal economic framework for assessing the sustainability of prolonged attritional warfare. Using the ongoing Russian invasion of Ukraine as a case study, the paper models the interaction between military production and consumption (losses) to evaluate the limits of state endurance under sustained conflict. The core of the analysis is a differential function of the war economy, defined as the net capacity to sustain operations over time, which is the difference between production and losses. This function is embedded within a theoretical construct that distinguishes between sustainable and unsustainable operational regimes, marked by critical thresholds of system exhaustion. Through a combination of regression analysis and symbolic modelling, the paper demonstrates how Russia’s current attritional strategy may be approaching a structural breaking point. The findings offer a conceptual and empirical basis for evaluating wartime industrial resilience and may inform strategic policy and conflict forecasting.

Accurate meteorological data is crucial for precise artillery fire, yet its availability can be compromised in combat conditions. This study investigates the impact of limited meteorological information on artillery accuracy and explores potential mitigation strategies. By analysing upperair data from a single weather station, we simulated various scenarios of reduced meteorological support. Our findings highlight the significance of meteorological factors on artillery performance and the potential consequences of inadequate data. We developed a foundational framework for offline artillery support products, emphasizing the need for robust methods to estimate atmospheric conditions in data-scarce environments. Future research will focus on incorporating advanced modelling techniques and additional data sources to enhance the accuracy and applicability of these products.

This article deals with one of the approaches to command - Mission Command - which can be seen as a dominant command philosophy in NATO nations and especially in the United States. This approach is considered as a very important in terms of possible responses to the challenges having impact on current and future security environment. Respective parts of this article describe the military causes and related historical consequences based on which the mentioned command philosophy had been constructed. The relevant parts describe basic principles of Auftragstaktik, developed and implemented by Prussian and later on by German military leaders which aim is to emphasize centralized intent and dispersed execution through disciplined initiative.

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.

This article aims to highlight the most important changes within the transatlantic defense relations. The central argument is that NATO is gaining a conditional nature, transforming collective defense into a form of transactional defense. The study utilizes Paul Kennedy's notion of "imperial overstretch" to explain the strategic context of the transatlantic defense relations. After this, the analysis highlights how the transatlantic defense relations gained a transactional character that is resonating to this American "imperial overstretch". The second part of the study focuses on the latest developments concerning the US military presence in Europe and highlights their transactional character, thus enabling the emergence of transactional defense within NATO.

Changing security environment and the need to address conventional and especially asymmetric threats and risks, wherever they occur, establish clear requirements on the development of national capabilities. Armed forces are required to be fully deployable and sustainable in operations in austere conditions for an extended period of time. In NATO-led operations currently participate many nations of different sizes, force structures, equipment, training and capabilities. The only way to reach operational goals while achieving economies of scale is a mutual cooperation of all involved participants. Basic key prerequisite for such cooperation is interoperability.

The paper is focused on research of military operations planning with the purpose of defining an efficient decision-making model at the tactical level for brigade-level offensive operation. Suggested model applies methods of multi-criteria decision-making – DIBR II (Defining Interrelationships Between Ranked Criteria II) and EDAS (Evaluation based on Distance from Average Solution) in order to decrease subjectivity while evaluating and ranking criteria, but also to select the most optimal course of action (COA). DIBR II method is used for the evaluation and determination of criteria coefficients, while the EDAS method enables choice between the most optimal COA. Application of simple and effective methods of multi - criteria decision - making accelerates the planning process and enables commanding officer to make optimal troop employment decision in a given operation.

After the year 1990 a total of 120 wars have taken place. The most appealing were those initiated by the USA, in which other friendly states´ve participated as well. No country has the right to invade its neighbour or over-run and annex another. There were many discussions in the world over the legacy of imposed interventions, under which conditions they are true and just. The study covers two dissimilar attitudes: the first one against Hussein's expansionist policy in 1991 and warfare after 9/11 2001. The legitimacy rests upon Resolutions of the United Nations Security Council that allow any nation to remove the aggressor by force. The author also mentions a series of wars, fought throughout the former Yugoslavia from 1991 to 1995, and then again from 1998 until 1999/2001.

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 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 holistically assesses the US application of security-development nexus (SDN) through the most known example of SDN in practice - provincial reconstruction teams (PRTs) - to elucidate what lessons learned can be drawn from there. The PRT's unique small footprint approach aimed to skip combat phases and focus on development in Panjshir. The research detected fourteen lessons learned from PRT's Panjshir wrongdoings and relatively successful initiatives. Lessons learned include defining mission objectives, early identification of instability sources, unified funding, emphasis on security sector reform, cultural awareness, empowering locals, and continuity in leadership and mission. PRT Panjshir's approach is debated, emphasizing managing, not fully resolving, complex conditions. Depending on contextual factors and learned lessons, the model's duplicability in future conflicts remains uncertain.

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.

This article deals with the use of constructive simulation software in the planning process of military engineer staff personnel. The possibilities regarding the implementation of MASA SWORD simulation software are demonstrated on specific data from the Engineer Support Management Course, with overlapping applications to other specialized military troops. Three scenarios were used for the simulations, which were practiced and verified during the course’s  exercise. Each scenario was evaluated in silico within the simulation environment, incorporating analytical and graphical outputs. Utilizing the MASA SWORD analytical module, each scenario underwent comparative analysis using statistical tests to assess the fulfilment or failure of the assigned task. The findings emphasize the promising role of constructive simulation in enhancing military personnel training and planning process on tactical level.

In the light of neorealist theory, the Eastern enlargement of NATO satisfies basic feature of expansion: 9 former countries of the Warsaw Pact become members of NATO. USA as a Sea power reinforced its superiority at the detriment of the RF as a continental power. The annexation of Crimea, as a Russian answer, had intensified security fears of post - Soviet countries and of Poland and enlarged the space for external balancing of the USA. Author warns that a confrontational structure had become typical for the area or the Western part of the Post - Soviet space. It increases the number of military incidents, and, even, the threat of a direct military confrontation including a Russian use of tactical nuclear arms, being inspired by the Rogers plan from 1980´s.

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 article deals with the issue of methodological approach to scenario development. This paper describes the methods and techniques used in scenarios development both in civilian sphere and within NATO and the EU, with an emphasis on their role in the military capability development process of the armed forces. The article defines the usual scenario construction process and describes the location and differences of generic and specific planning situations. In addition, the principles necessary to create quality scenarios are described here. The conclusion of the article deals with proposals focused on the elaboration of a methodology for scenario building in the Czech Armed Forces as part of the project "Strategic Alternatives to the Construction and Development of the Czech Armed Forces", which is being elaborated at the Center for Security and Military and Strategic Studies of the University of Defense in Brno.

This paper deals with the issue of logistics planning – one of the seven planning domains of defence planning in the Ministry of Defence Department of the Slovak Republic. In the framework of the descriptive research problem, the author was looking for an answer to the question: How is logistics planned in the defence planning system at the departmental level? The article contains the results of theoretical and empirical research carried out on the given issue. The author explains the main theoretical background of the research issue, describesin more detail the methodology of logistics planning in the conditions of the department as well as current knowledge and experience from practice, points out the most significant problems in the field and proposes their possible solutions.

The process of procuring military equipment, technology, material, and associated services (VM) is frequently shrouded in concerns about cost-effectiveness and, in some instances, even becomes the focus of law enforcement investigations. This often leads to delays in strategic investments and exposes involved individuals to the risk of criminal charges. Additionally, there is a notable lack of capacity to impartially evaluate the overall investment's efficacy. Consequently, the "Znalec" (Expert Witness) project was initiated as a part of the defense research program. Its objective is to explore the feasibility of establishing an expert institute that could impartially assess the value of the military procurements, set a standard for evaluating these assets, and outline a training program for relevant experts. This paper specifically addresses the first objective of the project, proposing a legal framework for the expert institute based on an extensive systems analysis.

Participation of experts form NATO member and partner countries in security situation development trends together with related military implications is meanwhile the newest mean of member states engagement onto NATO Defence Planning. In one hand this possibility is a way to gain findings from national experts and in other hand an opportunity enabling countries to enlarge knowledge and experience of national participants in order to development of similar activities at national level. Moreover there is an opportunity to present activities of nations´ institutions working in the similar field as well as national findings linked to security trends and defence planning. The author concludes that the Czech Republic has not yet formulated its own defence planning process, and suggests the possible effects of this condition
