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 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.

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.

On the one hand, Russia is among the countries which often criticize the Western-led military intervention. On the other hand, in the last twenty years, Russia has repeatedly approved using military force by the West against an individual state, endorsed by the United National Security Council. The main purpose of this article is therefore to describe and analyse Russian position towards four Western military interventions 1999-2011. Specifically, the article is focused on two military interventions without UN Security Council mandates (Federal Republic of Yugoslavia in 1999 and Iraq in 2003), the intervention with the expanded UN Security Council resolution (Afghanistan 2001) and the military intervention that was partially approved by the UN Security Council resolutions (Libya 2011).

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 article deals with the problems of current "military engineering" in Czech Army, which arose during drawing up the "Doctrine for land forces operations". The content of this article consists mainly of three parts. The first one has to characterize some doctrine development aspects from the engineer's contributor point of view. Secondly, to adduce requirements for the content of a doctrine which are consequent to NATO main military engineering documents, e.g. MC 0560, AJP-3-12(A) and ATP-52(B). Thirdly, this level has to evoke resourceful discussions on topical military engineering within military community and to contribute to the mutual opinion consensus achievement.

The authors present the results of the research on the Lessons Learned process applied within the Ministry of Defence of the Czech Republic. The main purpose of the article is to introduce the proposal of the process optimization to readers. The paper describes the process in detail, and this description is used to identify procedural shortcomings exploiting the process analysis method in terms of factual and logical accuracy of the process. The following part of the article presents the results of the comparative analysis of the chosen Lessons Learned processes. The result of the comparative analysis allows authors to make in an innovative way suitable recommendations for optimizing the current state of the whole process of Lessons Learned. Based on the analysis of the educational programs, the paper proposes to include the subject of the Lessons Learned process into the learning outcomes, especially from the perspective of competency based approach to education.

This study deals with long-term monitoring of physical fitness of soldiers, namely members of the 31st Radiation, Chemical and Biological Protection Regiment in order to determine whether the annual fitness test has rising trend, or in another words, whether the military service physical training process is fittingly effective. The study was carried out by comparing the assessment of physical fitness each year 2012-2019. The monitored group consisted of 316 professional soldiers, who participated in this assessment regularly, without interruption in the same disciplines.
Due to the managed long-term military physical training process, overall improvement in the strength and endurance disciplines throughout the monitoring period took place.
Based on the acquired data, it may be stated that the annual testing showed rising trend and thus the efficiency of the in-service physical training process proved to be good and appropriate.

Government controls state executives by planning, i.e. a bureaucratic process providing sets of documents. Such plans ought to be feasible in an expecting resource environment. Approach and methods using for working out respective plans are supposed to be conforming to the purpose. In order to be realistic, a financial plan, a budget, should cope with environment of increasing and decreasing prices and exchange rates. This essay, as a case study, deals with the issue of adapting of the short and medium-term planes working out by the Czech MoD for purpose of programming, budgeting and purchasing. The case study shows that generally there is a long-run lack of interest in adapting of such planes to an environment of changing prices and volatile exchange rates.

Authors of the paper present results of research in the area of deployment and operation of multirotors, i.e., autonomous aerial systems with vertical take-off and landing (VTOL) capability. Survey of Czech Army experts' opinions based on the Delphi method points to the significance of MINI VTOL UAS project undertaking - reconnaissance VTOL autonomous aerial system. The conclusion of the analysis is the identification of the primary applications of and requirements for (concept, system, and training) successful deployment of multirotors, with framing of existing issues of technical, acquisition/program and legislative nature, and determination of their importance. The paper also explores experts' views to the acquisition and operation of multirotors in Czech Army to achieve their full operational potential, certainly available in the future battlefield. Inconsistent architecture of information sharing was identified by experts as one of the most important issues with the highest likelihood of solution in the upcoming years.

Biosafety and biodefense (i.e. all countermeasures preventing the spread of biological agents in the environment and population) are on the regular agenda of states and their militaries. Somewhat aside are global catastrophic biological risks (GCBR), which can destroy human society as a biological species. Although a precise definition of what constitutes a global catastrophic biological risk is still being sought, it can be considered the impact of potential global catastrophic risks (GCR) on the social, economic and biological structure of human existence. This implies that GCBRs are a subset of GCRs. It is also open to discussion whether in the case of GCBRs the risk must necessarily be biological agents, from viruses to humans, or whether anthropogenic threats can also be accepted as risk factors, or what the impact must be for a risk to be included under the designation GCBR.

Grey Rhino is a metaphor for security threat, which is unkept irrational for large extent also high probability of harmful effect on a subject of risk owner. Business continuity management system is assessed in a diagram as controlling instrument aimed at operational hazard mitigation of continuity disturbance of affected subject. A ´from Operations´ Value Added - O´VA is established as qualitative dynamic information about productivity of activities. The measures are designed in crisis scenario for quality improvement of subject´s crisis readiness. An indicator of business risk continuity slip is defined. In a connection with war conflict on Ukraine is assessed if it is Grey Rhino manifestation.

The aim of this paper is to contribute to scientific research in the field of examining the shortcomings in the use of strategic communication for armaments. A comprehensive approach that rationalises the political, military, economic and technical decision-making process, as well as appropriate strategic communication with stakeholders, is required for the procurement of military equipment for the armed forces. The paper first analyses the existing shortcomings in the use of strategic communication in support of armaments, and then recommends a model for the adequate use of it. The results of a questionnaire survey and structured interviews with specialists in strategic communication and armaments show a high level of support for the use of strategic communication. However, the selected case studies on the Pandur and BVP modernization projects did not confirm the assumption of an improvement in the ability of the Czech Ministry of Defence to acquire new military equipment.

Chemical, Biological, Radiological and Nuclear (CBRN) weapons still represent a relevant threat despite international treaties and regulations. International projects like the Permanent Structured Cooperation (PESCO) of European Union (EU) appears as a suitable way of the further development when considered both complexity and expensiveness of the countermeasures to the CBRN. In this work, basic principles of PESCO, limitations, opportunities and expected directions of innovations were searched. The final recommendations on PESCO projects in the CBRN field are founded on the reached findings. Recommendations and conclusions on limited PESCO efficacy on one side and opportunity to resolve weakness of the Army of the Czech Republic (AČR) in the CBRN by collaboration in the EU on the other were particularly described in this paper. Without the collaboration, the AČR will hardly reflect the progress on CBRN defense.

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 paper describes a design concept of a lightweight armoured vehicle set "S-LOV-CBRN". The equipment of this set allows its crew to carry out a safe reconnaissance activities in areas with unknown situation under chemical, biological and radiological risks (CBRN reconnaissance), as well as the risk of contact with armed opponents.

The purpose of this paper is to present some particularities of mission command during the conflict in Ukraine. Intended as a  framework of analysis, it describes the ways in which the involved parties manage warfighting from the perspective of practicing mission command as a method to enhance military effectiveness. Using qualitative methods, combining literature review, critical analysis of relevant resources, comparative analysis and indirect observation, the findings are related to aspects of mission command that are critical for enhancing operational and decision-making resilience, through identifying and examining various situations involving Ukrainian and Russian military forces. At the same time, the results of the study highlight some potential ways of innovating the principle

On the introduction, the article focuses on clarifying the place and role of counterinsurgency in current military operations. It also deals with the principles of counterinsurgency and their doctrinal comparison within some advanced armies and the NATO. The aim is to highlight some findings related to principles that should be changed,added in doctrine and incorporated into the training of the ACR troops. The result of the analysis and comparison of individual principles with own experience of the author from the mission in Afghanistan are recommendations given for the troop training in the theatre. The implementation of the proposed measures in preparation of the Czech Army units may improve the effectivenessof counterinsurgency in military operations.

The Armed Forces of BiH were officially unified in 2005 and are composed of two founding armies: the Bosniak-Croat Army of the Federation of Bosnia and Herzegovina and the Bosnian Serb Army of Republika Srpska. Even though the unified armed forces celebrated their 13^th anniversary in December 2018 and are presented as a success story, the political environment in Bosnia and Herzegovina, particularly in Republika Srpska, does not foster a sense of unity in the armed forces. The paper explores the vulnerabilities that the unified armed forces face, particularly in relation to the process of state building in Bosnia and Herzegovina. The text concludes, that the main concerns for the BiH armed forces include the old equipment, the economic problems of the country and budget constraints, politicisation and ethnicisation - while ongoing nationalism and the unsure future of BiH remain the greatest external challenges.

Similar to the Czech Republic, all NATO nations have their own military territorial administrative authorities that both execute tasks of state administration and at the same time fulfil assignments of territory defence. Their overall numbers differ and mostly depend upon the fact whether the country has compulsory military service, alternatively military service is voluntary (professional army). Or as in the case of Greece, the scheme of Military Territorial Authorities is influenced by security situation in neighbouring areas. The author deals with Slovakia, Poland, Germany, Greece, and Spain. Those authorities have basic influence on recruitment, and manning, which is especially important in time of crisis, as the authorities have prepared manning system to increase numbers to prescribed volume.

This article deals with the Czech defence industry and its role in the defense policy of the Czech Republic. The basic goal of the text is a short introduction to abilities of the Czech defence industry and answering the question if and how it is able to fulfil the demand of the Czech defence sector for an armament and a military gear. Basic items needed for a military capability of soldiers on a field and the ability to develop and produce them at the Czech territory is mainly examined.

Based on the content analysis method, this study analyzes the first ever published security strategy of the Israel Defense Forces, which was published in 2015. The main objective of the paper is not only to present the circumstances of its creation and discuss the main objectives of this strategic security document, but also to outline the broader geopolitical context from which it emerged. The authors argue that the document primarily emphasized two areas - the use of force and capacity building of the Israeli military. Among other things, the publication of the strategy was intended to have a deterrent effect. In the conclusion, the authors compare the Gideon Plan and its follow-up, the Tnufa Plan, and point to the considerable importance that consensus among political and military elites has in the implementation of such a document and reflect on what lessons and inspiration can be drawn from this case in our geographic space in the process of formulating or reformulating strategic security documents.

This study deconstructs the concept of active measures through the prism of information influence. It understands it as sophisticated methods of influencing public opinion and political decisions, originally used by the Soviet Union and now adapted to cyberspace by the Russian Federation. In the analysis, the concept is contrasted with the general abstraction of information influence. This helps to better understand the proximity of active measures to similar concepts. We conclude that abstractions of information influence are also valid for conceptual understanding and practical examples of contemporary Russian active measures. Active measures are subsidiary to information influence, serving as tactical means to achieve the latter's strategic goals. Furthermore, the author states that the information environment is the operational theatre for active operations, cyber operations can be its manifestation, information operations support as a key component of a broader information operations strategy, and psychological operations are its critical element.

The article deals with some military consequences of the departure of the United Kingdom of Great Britain and Northern Ireland from the European Union (Brexit). To assess the potential impacts on defence and security of EU, a structured approach involving several methods was used in the analysis, which combines a search of professional publications, factors sensitivity analysis and testing of hypotheses. Based on the analysis, it was evaluated that the departure of the United Kingdom of Great Britain and Northern Ireland from the structures of the European Union will take place without significant impact in the military field and does not pose an immediate threat to the security and defence of EU member states. Nevertheless, in connection with Brexit, there is still a certain risk of negative impacts in this area.

The article concerns the issue of arson attacks in Israel.The issue of terrorism in Israel is quite broad, given that it is a very common phenomenon here and Israel deals with terrorism on a daily basis. The paper therefore focuses on incendiary balloons, a weapon that repeatedly caused fires around the Gaza Strip between 2018-2023. It examines their history, their design, outlines the possibilities of their elimination, the advantages and disadvantages of possible technical solutions, and a reflection on the future of their usage.

Most experts believe that urban operations will gain importance in the future, but even though we have sufficient examples and experience at hand, we still struggle with the development of the necessary skills and capabilities. The resulting gaps are a combination of different tasking and shrinking resources in the past decades, the difficulty of training for and a mere misunderstanding of the urban environment and harmful innovations - we seem to find ourselves always in the beginning. Fighting in isolated "prisms of responsibility" requires flexible task forces with all necessary enablers at hand and well-trained commanders exercising mission command and understanding their role, task, and the purpose of action. Mastering the urban environment on all three levels of movement is a very challenging task and requires focused attention on various aspects, inter-actor interaction and interdisciplinary research and development. The development of a methodology suitable for looking into the hidden aspects and contextualizing them with current activities and future developments is key to capability development.

Current War in Ukraine represents conventional conflict of high intensity unparallel in contemporary European history. Using a qualitative method, authors present character of the war and identify its key specifics through multi-domain optics. A preliminary set of recommendations is derived from these results for the national defense capability of Czech Republic. Authors conclude that both State and the Armed Forces must increase their readiness for the large-scale conflict.

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.
