The Changing Security Paradigm in the Israel-Iran Conflict: The Concept of the New Battlefield and Multi-Layered Defence

The concept of the battlefield has undergone transformations throughout human history, parallel to the nature of war and technological capabilities. From ancient times to the present day, the battlefield has evolved from a mere geographical space into a multi-layered arena of struggle with political, economic, technological and psychological dimensions.

The Battlefield in Ancient Times: A Place of Physical Contact

Ancient wars were limited to physical areas where armies faced each other in open fields and tactical manoeuvres and hand-to-hand combat took place. For example:

• Greek and Roman armies preferred to engage the enemy on flat terrain.
• Geographical features (hills, rivers, forests) were factors that determined the tactics of war.
• Logistical factors, such as proximity to water sources and the security of supply routes, were influential in the choice of battlefield.

The Middle Ages and the Modern Era: Castles and Siege Warfare

In the Middle Ages, wars were mostly defensive in nature and took place around castles. During this period, the battlefield was no longer just open terrain, but took on a much more static structure consisting of walls, moats and passages.

• Siege warfare became widespread.
• Logistics became decisive in supplying castles and sustaining sieges.
• During this period, cities were part of the battlefield as both economic and strategic centres.

The Modern Age and Post-Industrial Revolution: Mobile Fronts

In the 18th and 19th centuries, with the spread of firearms and the development of transportation infrastructure such as railways, the battlefield began to be defined as mobile front lines:

• The Napoleonic Wars were fought across vast territories with high mobility.
• Clausewitz viewed the battlefield as a theatre of struggle involving not only land but also ‘all the physical and moral resources of the state.’
• Railways, telegraphs and steam power expanded the battlefield and brought logistics to the fore.

20th Century: Total War and Multidimensional Fronts

With the First and Second World Wars, the battlefield took on the form of total war, in which not only soldiers but also the entire society and infrastructure became targets:

• Air strikes turned cities into direct battlefields.
• Economic targets (factories, ports, energy lines) became integrated with military targets.
• Logistics became central to the sustainability of war.

21st Century: Hybrid Wars and the Erosion of Borders

The battlefield has historically been defined as a concept limited to physical geography. However, in the 21st century, this concept has evolved into a multidimensional structure with the spread of technological developments and hybrid warfare techniques. Historically, the battlefield has transformed from a narrow geographical space to a global, multi-layered and dynamic terrain in parallel with technological and strategic evolution. The battlefield is no longer just the front line; it is now the airspace, cyberspace, media environments, energy lines and even supply chains.

Today, the battlefield has completely transcended the classic definition of the front line:

• Cyber attacks have shifted the battlefield to the digital realm by targeting information infrastructure.
• Drones and artificial intelligence-based systems enable actors outside traditional armies to be effective.
• Psychological warfare, media manipulation and economic sanctions have also become tools of war, making the battlefield both invisible and multidimensional.

The Expanding Definition of the Battlefield

In traditional warfare, logistics aimed only to secure the supply lines of military units, whereas in modern warfare, logistics has become a broad security domain that also encompasses information, communication and energy flows. In this context, the battlefield should be defined in terms of

• Physical (land, air, sea),
• Digital (cyberspace, communication infrastructure),
• Socio-political (public support, perception management) dimensions.

The Battlefield Dimension of the Israel-Iran Conflict

The geopolitical tension between Israel and Iran goes beyond conventional warfare and is being conducted through asymmetric and hybrid warfare strategies. In this context:

Iran's long-range missile capabilities and Israel's technological air defence systems (Iron Dome, David's Sling) are shifting this conflict to the level of ‘high-tech asymmetric warfare.’

In the 21st century, the concept of the battlefield is no longer limited to physical fronts; it has become a multi-layered arena of struggle that extends to digital, economic, psychological and socio-political dimensions.

This expanding war environment has forced us to redefine the concept of security and develop multidisciplinary strategies.

Security is now considered not only in terms of military superiority, but also in terms of data protection, supply chain security, perception management and the protection of energy infrastructure.

Characteristics of the New Generation Battlefield

The new generation battlefield can be defined in five basic dimensions:

· Physical Domains: Land, air and sea elements

· Cyberspace: Information systems, communication infrastructure, digital attacks

· Space: Satellites, GPS systems, satellite communications

· Economic Front: Energy lines, trade routes, financial systems

· Psychological/Socio-political Domain: Media, public perception, disinformation

New Dimensions of Security

Cyber Security: One of the most vulnerable fronts of modern warfare is the cyber domain.

· Critical infrastructure (energy, finance, transportation) of states is under threat of cyber attacks.

· Cyber security strategies are now a fundamental part of the defence industry.

· Cyber deterrence and attack detection have become priority dimensions of security.

Supply Chain Security: Global production dependency can cause significant vulnerabilities in times of war.

· The supply of critical components for military and civilian systems may be targeted.

· Alternative supply routes, domestic production and storage strategies have gained importance.

Energy Security: Energy infrastructure is a strategic target in modern warfare.

· Oil pipelines, power plants and LNG terminals are at direct risk of attack.

· The security of energy resources affects both military and economic security.

Information Security and Perception Management: Public perception has reached a level that will determine the success of war.

· Disinformation, propaganda, and social media operations are targeting internal stability.

· Media and digital platforms are both tools and battlefields in modern warfare.

Case Study: The Russia-Ukraine War and Security Dynamics

The Russia-Ukraine war, which began in 2022, has vividly demonstrated the scope of new-generation security:

· Russia's attempts to disrupt Ukraine's communication infrastructure through cyberattacks

· The widespread use of drones and UAVs

· Supply chain disruptions and Western energy sanctions

· A global perception war waged through media and social platforms

Multi-Layered Defense Approaches

Security can no longer be ensured through a hierarchical structure and a holistic approach; integrated and flexible security strategies are required in the new generation battlefield. The scope of the new defense model is as follows:

Conclusion: Security is being redefined

In the new generation battlefield, security no longer encompasses only the protection of weapons on the front lines, but also the protection of algorithms, satellite systems, public opinion, and logistics lines. Ensuring security is possible through interdisciplinary cooperation, technological investment, intelligence coordination, and social resilience. In this new paradigm, logistics and information security will be the backbone of future national defence strategies.
