Military reforms are about developing leaders capable of navigating the intersection of warfare, technology and organisational change
Lt Gen Karanbir Singh Brar Retd
HE debate on military reforms and theatreisation has rightly highlighted an important reality: military transformation cannot be the responsibility of a single individual, institution or appointment. While the creation of the Chief of Defence Staff (CDS) and the efforts toward jointness and theatre commands are significant milestones, they represent only one part of a much larger transformation that the forces must undertake.
The central challenge facing militaries worldwide today is adaptation to a rapidly changing character of warfare. The nature of war may remain constant, but the means through which military power is generated, exercised and sustained are undergoing a profound change. Consequently, military reform must be viewed not only through the lens of structures and command arrangements but also through the lenses of technology, human capital, doctrine and national capability.
The future battlefield is increasingly defined by technologies that transcend traditional service boundaries. Multi-domain operations (MDO), integrated intelligence, surveillance and reconnaissance (ISR), net-centric warfare, sensor-to-shooter architectures, AI-enabled decision support, cyber warfare, electronic warfare, autonomous systems, drones, robotics and space-based capabilities are redefining how military power is applied.
In such an environment, military effectiveness will depend less on the number of platforms a nation possesses and more on how effectively it connects sensors, decision-makers and effectors across all domains.
The decisive military advantage of the future will not come merely from possessing tanks, aircraft, ships or missiles. It will come from achieving decision superiority – the ability to observe, orient, decide and act faster and more accurately than an adversary.
This requires integrated systems, common operational pictures, secure communications, data fusion, AI-enabled analytics and resilient networks. Theaterisation can facilitate such integration, but it cannot create it by itself. A theatre command without integrated data architecture may simply become three services operating under a common headquarters. True transformation demands much more.
If future military capability is tech-driven, then military reforms and technological self-reliance become inseparable. India’s pursuit of Atmanirbharta in defence must therefore extend beyond manufacturing platforms. Indigenous production of equipment is important, but the future battlespace will increasingly be shaped by control over software, algorithms, data, communications, cyber capabilities, sensors, semiconductors, autonomy, and artificial intelligence.
Dependence on external sources for critical technologies may create vulnerabilities far more significant than dependence on traditional military hardware. AI models, data repositories, operating systems, communication networks, cyber tools and digital infrastructure are becoming strategic assets. Technology-driven military reforms therefore require technology-driven Atmanirbharta.
This demands a national effort involving the armed forces, academia, startups, industry, research institutions and policymakers. Defence capability can no longer be viewed solely as the output of military organisations. It is increasingly the product of an entire national innovation ecosystem.
Much of the military leadership architecture of today was designed for the industrial-age military. The challenges of the future are different.
The AI age requires leaders who can operate simultaneously in the physical, informational, cyber, cognitive and technological domains. It requires institutions capable of rapid adaptation. It requires closer integration between military organisations and national innovation ecosystems.
Most importantly, it requires recognition that military reforms extend far beyond headquarters’ reorganisation. Theaterisation, jointness, and organisational restructuring are necessary. But they are only part of the solution.
The larger challenge is creating a force capable of achieving decision dominance in an era characterised by data abundance, algorithmic warfare, autonomous systems, cyber contestation, and persistent surveillance.
The discussion often evokes an important counterpoint – that while technology continues to advance at an unprecedented pace, the enduring principles of warfare remain unchanged. Leadership, judgment, initiative, courage, strategic foresight and operational art will always lie at the heart of military success. The art of war therefore retains its relevance and primacy.
However, the challenge before modern militaries is not one of choosing between the art and the science of war. It is about understanding how the science of war is increasingly shaping the manner in which the art of war is conceived and executed.
Historically, technological change certainly influenced warfare, but its impact on operational decision-making and battlefield outcomes was often limited by the pace of information flow and the relative simplicity of military systems. Today, the relationship has fundamentally changed. Artificial intelligence, integrated ISR networks, cyber warfare, electronic warfare, space-based capabilities, autonomous systems and sensor-to-shooter architectures are no longer peripheral enablers. They increasingly determine how commanders perceive the battlefield, generate situational awareness, make decisions and apply combat power. They are becoming central instruments through which military commanders achieve operational effects.
A commander who lacks technological understanding may struggle to exploit emerging capabilities effectively. Equally, technologists who lack understanding of warfighting realities risk creating solutions in search of problems.
The art of war and the science of war can therefore no longer be viewed as separate domains. Modern operational art is increasingly exercised through technological systems. A commander may still rely on intuition, experience and judgment, but these are now informed by data, algorithms, networks and machine-assisted decision support. The commander remains central, but the tools through which command is exercised are undergoing profound transformation.
The military challenge of our era is therefore not preserving the art of war from technology but incorporating the science of war into it. Those who master both will shape the future battlefield; those who treat them as separate disciplines risk being overtaken by adversaries who understand their convergence. That convergence is the real driver behind the transformation of modern warfare.
Therefore, framing the debate as a choice between the art of war and the science of war is not appropriate. The reality is that modern warfare increasingly demands mastery of both. The challenge is integrating them. It might well now be termed as “art & science of war”.
It naturally leads to the conclusion that future leaders must understand warfighting, technology and transformation simultaneously because the art and science of war are now inseparable.
Organisational reforms or technological infusion does not transform organisations by itself. People do.
The success or failure of military reforms will ultimately depend upon whether the armed forces can develop leaders capable of understanding and integrating operational requirements, technological possibilities, and institutional change.
This may require a new category of military leadership – what may be termed the “three-dimensional officer.” Historically, military leaders were primarily expected to master operations and command. In the future, that will remain essential but no longer sufficient.
Three-dimensional officers, particularly at the two-star and three-star levels where capability development and institutional transformation are shaped, must possess three distinct competencies.
First, they must have a comprehensive understanding of the operational environment across the spectrum of conflict and all domains of warfare. They must be capable of identifying operational challenges and translating them into future capability requirements and warfighting use cases.
Second, they must possess sufficient technological understanding to engage meaningfully with scientists, engineers, startups, academia and industry. They need not become technologists themselves, but they must understand what technology can and cannot do. They must be capable of guiding projects, evaluating outcomes, and ensuring that innovation remains aligned with operational requirements.
Third, they must be able to integrate emerging capabilities into doctrine, operational concepts, force structures, training systems, and war plans. Military innovation is successful only when technology becomes embedded within the way a force fights.
Possessing one or even two of these dimensions is no longer enough. Future military leaders must master all three. The critical question is therefore not whether India possesses talented officers. It undoubtedly does. The more important question is whether our institutional structures, education systems, career pathways, and promotion models are producing enough three-dimensional officers – or whether they continue to reinforce functional and service-specific silos.
Military reforms are therefore not merely about changing structures. They are about transforming capabilities. They are about building technological sovereignty. They are about creating institutions that learn faster than their adversaries. And above all, they are about developing leaders capable of navigating the intersection of warfare, technology and organisational change.
Military reforms are indeed not a one-man act. Nor are they merely an organisational exercise. They are a national endeavour requiring vision, military leadership, technological innovation, industrial capability and a new generation of three-dimensional officers who can convert technological possibilities into operational realities.
That may well be the defining challenge of military transformation in the twenty-first century.
