Military security based on EU and NATO alliances, cooperation, and Poland's strategic role in the east.

Military security presentsregulated legal standards, in which each country of the European Union, along with other allied treaties, responds in the event of its own or allied threats.

An example of such actions is the NATO Alliance Area and the EU concerning the lands located on the Eastern border of the Republic of Poland. Each alliance, treaty, and legally signed document must include and describe the security of the region of already signed alliances, but every Ally must remember that each country, that is, the region of a given state, without appropriate state safeguards will not be an effective mechanism entering into any Treaty and Alliance. Only joint regional actions in a given state will allow for quick and effective action when it comes to joint economic, economic, military actions, and armament processes. Joint communication systems, similar mechanisms, and production devices will enable effective cooperation. In the example presented below regarding Poland, I define an important element which is the military security of a given allied region, which is its State. Poland has the biggest problem, which arises because it is both a NATO Ally and an EU member and also a country that borders other countries and other Allied treaties, such as the Russian Federation and allies of aggressive war supports related to UKRAINE.

Military securityin a scientific perspective, is defined as the state and process in which a state ensures the protection of its vital interests, such as sovereignty, independence, and territorial integrity, against military threats. It is a fundamental component of national security, focusing on the state's ability to counter the use of armed force or the threat of its use by other actors on the international stage.

Experts in the field of security sciences emphasize the dual nature of this definition:

• In a static perspective (as a state):Military security means the absence of direct military threats to the state, which translates into a sense of certainty and peace in the defense dimension. It is a state in which the state's defense potential and existing alliances effectively deter potential aggressors.
• In a dynamic perspective (as a process):It is a continuous action of the state and its specialized institutions (primarily the armed forces), aimed at identifying, preventing, deterring, and responding to military threats. This process includes strategic planning, the development of defense capabilities, modernization of the army, maintaining military alliances, and conducting military operations.

A key condition for discussing threats in the context of military security is not only directing it against the state's key interests but also the potential or actual use of armed forces.

Key Elements of Military Security

Scientific analysis allows us to identify several key elements that make up military security:

• Armed Forces:They are the central instrument of the state for ensuring military security. Their number, equipment, training, morale, and command abilities are decisive.
• Defense Potential:It includes not only the armed forces but also the defense industry, strategic infrastructure, economic resources, and the mobilization potential of the state.
• Alliances and International Cooperation:Membership in military alliances (such as NATO) and cooperation with other states significantly strengthen defense potential and deterrence capability.
• Defense Strategy and Doctrine:A clearly defined concept of the use of armed forces and the entire potential of the state in response to identified threats.

Military security has historically been the oldest and one of the most important dimensions of state security, although contemporary perspectives emphasize its close connection with other sectors such as political, economic, or social security.[1]

military security of the European Union in the context of alliances and an explanation of the obligations of member states.

EU military security and alliance commitments is a complex area of research that focuses primarily on the interpretation and potential application of the mutual defense clause, enshrined inArticle 42(7) of the Treaty on European Union (TEU). It is the legal foundation that regulates what member states must do when one of them falls victim to armed aggression.

Main Scientific and Research Topics

In the scientific and strategic discourse regarding EU defense, several main research areas are distinguished that analyze the challenges and real capabilities of the Union.

1. Mutual Defense Clause (Art. 42.7 TFEU) and Article 5 of NATO

This is a fundamental comparative topic. Research focuses on the differences and similarities between the EU's clause and the famous Article 5 of the Washington Treaty.

• Nature of the obligation: Article 5 of NATO is perceived as more automatic ("an attack on one is an attack on all"). Article 42.7 TFEU obliges states to provide "assistance and support usingall means available to them"[2]. Analysts debate what exactly this formula means and what the threshold for its activation is.
• Role of neutral states: Unlike NATO, the EU has members with neutral status (e.g., Austria, Ireland, Malta). Research analyzes how these states can fulfill their obligations without violating their neutrality policy (e.g., through humanitarian, financial, logistical assistance, rather than necessarily military).
• First use: The only case so far of invoking Art. 42.7 is analyzed – by France after the terrorist attacks in Paris in 2015. It was a precedent that showed the flexibility of the clause; France requested bilateral support for external operations (e.g., in Syria and Africa), rather than for the collective defense of EU territory.[3].

2. Strategic Autonomy of the European Union

This is one of the hottest topics in European security studies. The pursuit ofstrategic autonomy means the EU's ability to act independently in the security sphere, without relying on external allies, mainly the USA.

• Military capabilities: Research focuses on real deficiencies in European armed forces (e.g., in strategic transport, satellite reconnaissance, air refueling). Initiatives such asPESCO (Permanent Structured Cooperation) andthe European Defense Fund (EDF) aim to fill these gaps[4].
• Political will: Scholars analyze whether there is a coherent political will among the 27 member states to build autonomy or whether it is mainly a French project that other capitals approach with caution, preferring NATO guarantees.
• Strategic Compass: This is a key EU document that outlines the directions for the development of security and defense policy until 2030. Academic analyses assess its real impact on building coherent armed forces, including the plan to create EU rapid response forces (up to 5000 soldiers)[5].

3. Division of Labor and Relations between the EU and NATO

For most EU members who are also NATO members, a key issue is avoiding duplication of tasks and resources.

• Complementarity vs. rivalry: The prevailing academic thesis assumes that NATO remains the foundation ofcollective defense (territorial defense), while the EU specializes incrisis management (stabilization, training, civilian missions outside the EU).
• Impact of the war in Ukraine: Russian aggression has reinforced NATO's role as the main guarantor of military security in Europe. At the same time, it stimulates the EU to strengthen its own defense industry and support mechanisms, which is the subject of intensive research.

What Must Member States Do in Case of an Attack on an Ally?

The obligations of member states in the event of armed aggression on the territory of one of them are defined by the aforementionedArticle 42(7) TFEU.

Step 1: Request from the attacked state

The state that has been a victim of aggression must formally request assistance from the other EU members, invoking Art. 42.7.

Step 2: Obligation to provide assistance and support

The remaining member states have a legal obligation to respond. However, it is crucial to formulate that they must do so "using all means available to them."

Step 3: Sovereign decision on the form of assistance

In practice, each state sovereignly decides what assistance it will provide. There is no mechanism that automatically sends troops under the EU flag. The form of support can include:

• Military assistance: Sending troops, equipment, ammunition, providing airspace.
• Logistical support: Assistance in transport, supply, medical care.
• Financial assistance: Direct budget support for the attacked state.
• Intelligence support: Sharing intelligence data.
• Political and diplomatic actions: Imposing sanctions on the aggressor, actions in the UN forum.

Important NATO context: For states that are simultaneously members of the EU and NATO, armed attack would very likely first triggerArticle 5 of NATO.. It is considered a stronger guarantee of security due to the unequivocal military commitment of the United States and better-practiced collective defense procedures. The EU clause is treated as complementary and reinforcing European solidarity.[6]

The defense of Poland, as a member state and also the eastern region of the European Union, is based on a multidimensional system that combines allied guarantees with mechanisms of economic, industrial, and intelligence cooperation. The foundation is European solidarity, which, although often viewed through a political and economic lens, also has a strong security component.

For Poland, as a border country of the EU, these mechanisms complement and reinforce the guarantees stemming from NATO membership. EU support manifests itself through joint funding of defense projects, building interoperability of the defense industry, and institutionalized exchange of key information.

Economic Alliance for Defense

Economic solidarity in the EU directly translates into the defense capabilities of member states. The Union utilizes its budget and financial instruments to strengthen the European technological and industrial base of the defense sector, which also benefits Poland.

The main mechanisms are:

• European Defense Fund (EDF): This is a key program with a budget of nearly 8 billion euros for the years 2021-2027, aimed at supporting cross-border cooperation of enterprises in research and development of defense technologies. Poland actively participates in projects funded by the EDF. For Polish defense companies and research centers, this is an opportunity to secure funding for innovations, technology transfer, and integration into European supply chains.[7].
• European Peace Facility (EPF): Although this is an off-budget instrument, it allows the EU to finance the operational costs of military missions and provide military equipment to partner countries. The unprecedented use of the EPF to support Ukraine has shown that the Union can mobilize significant financial resources to defend common security interests, which has direct implications for Poland as a frontline state.[8].
• Military Mobility: This initiative, financially supported by the "Connecting Europe" (CEF) instrument, aims to adapt civilian infrastructure (bridges, roads, railways) to the needs of rapid troop and equipment transfers within the EU. For Poland, as a transit country for allied forces, these investments are of fundamental strategic importance, shortening response times in crisis situations.[9].

Arms Support and Industrial Cooperation

The Union aims for the armed forces of member states to be more interoperable and capable of joint action. Poland is an active participant in these processes.

• Mutual Defense Clause (Art. 42.7 TEU): This is the EU equivalent of NATO Article 5. It states that "if any Member State is the victim of armed aggression on its territory, the other Member States are obliged to provide assistance and support using all means available to them"[10]. Although the form of assistance is a sovereign decision of each state, this clause creates a legal obligation of solidarity, which strengthens Poland's defensive position.
• Permanent Structured Cooperation (PESCO): Poland participates in several projects within PESCO aimed at the joint development of specific military capabilities. Examples include projects in cyber defense, land unmanned systems, military medicine, or military mobility. Participation in PESCO allows for the harmonization of equipment and doctrinal requirements with other EU armies, which is crucial for the effectiveness of joint operations.[11].
• European Defense Agency (EDA): It serves as a cooperation platform, supporting member states in identifying needs, developing capabilities, and conducting joint arms programs. For Poland, it is a forum for exchanging experiences and initiating research and development projects.

Joint Exchange of Information and Analysis

Effective defense requires proactive knowledge of threats. The European Union has developed structures that allow member states, including Poland, to exchange key intelligence and analytical information.

• EU Intelligence Analysis Center (EU INTCEN)Operating within the framework of the European External Action Service (EEAS), INTCEN creates strategic analyses based on intelligence data provided by the member states' services. Poland, as an active contributor, gains access to a broader picture of the situation, combining perspectives and sources from across Europe. This allows for better assessment of threats, such as hybrid or terrorist ones.[12].
• The EU Hybrid Fusion CellAlso within the EEAS structures, this cell analyzes hybrid threats such as disinformation, cyberattacks, and the instrumentalization of migration. For Poland, which is a target of such actions, access to EU analyses and early warning mechanisms is extremely valuable.
• Cooperation in CybersecurityThrough the ENISA agency and the network of Computer Security Incident Response Teams (CSIRT), the EU coordinates responses to cyberattacks. The NIS2 Directive imposes reporting obligations on key sectors of the economy and raises the overall level of resilience, which is a form of collective security in the digital dimension.

In summary, Poland's defense within the EU is a system of interconnected vessels, where military strength is reinforced by economic solidarity, industrial cooperation, and integrated information exchange, creating an additional layer of security that complements NATO.

EU Border Defense: Poland and the Defense Industry in the Service of Common Security

In the face of growing threats on the eastern flank of the European Union, Poland plays a key role in securing its borders, intensively engaging its defense industry in this task and tightening cooperation with EU and NATO allies. These actions include both national investments in defense infrastructure and participation in multilateral military initiatives and development projects, which translates into a real strengthening of the defensive potential of the entire region.

"Eastern Shield" and the Baltic Defense Line: Regional Integration of Defense Systems

A flagship example of Poland's engagement is the national program"Eastern Shield". It involves the construction of a comprehensive system of fortifications, barriers, and advanced monitoring systems along the border with Belarus and Russia. This project, for which the Polish government plans to allocate significant funds, aims not only to physically hinder border crossing but also to provide the Polish Armed Forces with favorable conditions for defense.

A key element of the "Eastern Shield" is its plannedintegration with the "Baltic Defense Line", a joint initiative of Lithuania, Latvia, and Estonia. This cooperation aims to create a coherent and interoperable defense system across the region. One specific example of this cooperation is Lithuania's purchase of Polish portable anti-aircraft missile systems (PPZR)"Piorun". This modern equipment, produced by the Polish defense industry, enhances Lithuania's air defense capabilities while facilitating the cooperation of the armed forces of both countries.

Cooperation within NATO and the EU: Interoperability and Joint Missions

Poland actively participates in joint missions and defense initiatives within NATO, which directly translates to the security of the EU borders. The Polish military contingent, equipped with F-16 fighter jets,F-16, regularly carries out missions underNATO Baltic Air Policing, protecting the airspace of the Baltic states that do not have their own combat aviation. The permanent presence of Polish soldiers and equipment on the eastern flank of the Alliance, as well as the location of key NATO command structures in Poland (including the Multinational Corps Northeast Command in Szczecin), significantly raises the level of interoperability and the ability to respond jointly in a crisis situation.

In response to the migration crisis triggered by the Belarusian regime, Poland launched operation codenamed"RENGAW". As part of this operation, advanced military equipment was deployed to the border, including wheeled armored personnel carriers"Rosomak", self-propelled mortars"Rak", and unmanned aerial systems"Bayraktar". These actions, although conducted under national command, are part of a broader strategy to protect the external border of the EU and take place with the political and logistical support of allies.

The Role of Frontex and the Polish Industry.

The European Border and Coast Guard Agency (Frontex), based in Warsaw, plays a central role in coordinating activities at the EU's external borders. The Polish Border Guard is one of the key partners of the Agency, regularly participating in joint operations and delegating its officers. Although the direct use of products from the Polish defense industry in Frontex operations is not widely documented in publicly available reports, Polish companies in the defense and technology sectors are developing systems that meet the Agency's needs. Examples include surveillance systems (including drones) and perimeter systems, which are crucial for effective monitoring and protection of borders.

Challenges and Perspectives

Despite increasing engagement and investment, cooperation in the defense industry within the EU faces challenges. Debates at the EU level, such as the proposal requiring that 70% of components in EU-funded projects come from member states, indicate differences in interests and protectionist tendencies among some countries. For Poland, whose defense industry is still integrating into global supply chains, such regulations could pose a barrier to development.

Nevertheless, the strategic necessity to strengthen the eastern flank, along with the growing awareness of common threats, stimulates further tightening of cooperation. Initiatives such as "Eastern Shield" and its connection to the defense of the Baltic states, supported by NATO engagement, show that Poland and its defense industry are, and will remain, a key element in the European Union's border defense system.[13]

Selected scientific sources and reports from which confirmed information can be obtained:

1. Centre for Eastern Studies (OSW) - regularly publishes analyses and reports on military cooperation on NATO's eastern flank, including on the interoperability of Poland's and the Baltic states' air defense systems. OSW reports indicate an increasing synchronization of military exercises and a drive for integration of defense capabilities.
2. Polish Institute of International Affairs (PISM) - provides analyses on EU security and defense policy. PISM publications discuss hybrid operations at the border with Belarus and Russia, as well as Poland's role in shaping the EU's response to these threats.
3. National Security Bureau (BBN) - publishes strategic documents and quarterly "National Security" journals, which analyze the role of the Polish Armed Forces and the Polish defense industry in the state security system and within the North Atlantic Alliance.
4. Official communications from the Ministry of National Defense of Poland - official information about the "Eastern Shield" program, cooperation with Lithuania (including the purchase of the "Piorun" MANPADS), and participation in NATO missions such as Baltic Air Policing.
5. Documents and reports from the European Union and Frontex - contain information about joint border operations, the budget for border protection, and strategic directions for the development of the European Border and Coast Guard.

Poland's defense is a multilayered system, where military strength is reinforced by economic solidarity, industrial cooperation, and intelligence sharing within the EU, serving as a complementary safeguard to the guarantees provided by NATO. Without these efforts, Poland's multilayered system would have to cope with many problems and threats in a different way.
