The New Battlefield: Cognitive/Semantic Warfare

Neuroweapons in Cognitive Warfare
When the Battlefield Is the Human Mind

In the evolving landscape of global conflict, traditional weapons are being replaced by more insidious and invisible tools. Among the most dangerous are neuroweapons — technologies and psychological strategies designed to directly manipulate, disrupt, or degrade human cognition, emotion, perception, and memory.

While cyberattacks target infrastructure, neuroweapons target the brain itself — the final frontier of warfare. These tools are not theoretical. They are being researched, tested, and in some cases deployed today under the broader umbrella of cognitive warfare.

If we fail to act now, these silent weapons will undermine societies from within, subverting free will, collapsing trust, and destroying the very faculties that make democracy and human dignity possible.

These tools may not kill but they can unmake a person, fracture a society, or erase shared reality.

Why Neuroweapons Are a Threat to Humanity

They Bypass the Body and Go Straight for the Self 
Unlike kinetic weapons, neuroweapons attack the core of identity: belief, memory, decision-making, and emotional balance. Victims may not even know they’ve been targeted until they’ve changed.
They Are Hard to Attribute and Easy to Deny
Neuroweapons leave no craters or scars. Their effects can be dismissed as mental illness, stress, or coincidence. This plausible deniability makes them the perfect tool for covert repression and political warfare.
They Can Be Used by Non-State Actors and ‘Black Sheep’ Insiders
It doesn’t take a state military to carry out neurowarfare. Rogue scientists, private intelligence contractors, criminal networks, or embedded actors in medical or tech systems can use them to target whistleblowers, activists, or civilians.
They Create Irreversible Damage to Minds and Institutions
Neuroweapons not only harm individuals; they erode public trust, delegitimize institutions, and degrade mental health at scale — leading to increased suicides, societal division, and economic collapse.

DARPA GARD: From Illusion of Defense to Semantic Weaponry – A New Era of Cyber Warfare

GARD — Guaranteeing AI Robustness against Deception. The deeper I plunged into its intricacies, the clearer it became: this narrative transcends mere defense, venturing into the creation of an entirely new, unprecedented class of weaponry. The catalyst for this discourse stems from the official DARPA document HR001119S0026 and the analytical brief “GARD: The Science of Deception from DARPA”, which collectively paint a picture worthy of a dystopian thriller. The unsettling truth is, this isn’t fiction; it’s unfolding in our reality, right now.

We have grown accustomed to placing immense trust in artificial intelligence. It orchestrates our financial markets, assists in medical diagnoses, pilots aircraft, and safeguards national borders. But what if this intelligence can be manipulated to perceive what is absent? Or, conversely, to disregard an overt threat? The GARD program is not merely another research endeavor. It is Pandora’s Box, unleashing an era of semantic warfare, where the battleground is the machine’s very perception of reality.

This journey began with what are known as adversarial examples — minute, humanimperceptible alterations within a digital image (e.g., in a few pixels) that provoke neural networks into making egregious classification errors. A quintessential illustration: a “STOP” sign, subjected to such an attack, is misidentified as an “80 km/h Speed Limit” sign. This is no longer a benign vulnerability; it poses a direct and severe threat to safety, particularly for autonomous vehicles.

However, DARPA, through its GARD program, propelled this concept far beyond its initial scope. The focus dramatically shifted from the purely digital domain to the tangible world. The official program announcement explicitly details attacks on physical objects, such as “placing stickers on a road sign”. This fundamentally reshapes the strategic landscape. Now, an adversary need not compromise code or gain access to a neural network’s internal architecture. It suffices to manipulate the very physical reality that the machine “observes.”

Assessing “Cognitive Warfare”

Defining Cognitive Warfare

In Cognitive Warfare, the message is the munition, and the target is the mind of either specific individuals (e.g., elites, influencers, policymakers) or the collective population of a democratic state. Distorting what these individuals think is a precursor to how they think, and thus how they behave.

Early advocates such as the French officer, Francois du Cluzel, defined Cognitive Warfare as “the art of using technologies to alter the cognition of human targets, most often without their knowledge and consent.”[8] This early conception stressed Cognitive Warfare as an offensive form of cyber conflict; however, he recognized that countermeasures and preventive measures were required. Du Cluzel differentiated psychological operations from cognitive operations, but it is unclear whether the distinction is valid or of value. For du Cluzel, psychological warfare attempts to change what the target audience thinks, but Cognitive Warfare aims at shaping how they reason and their resultant behavior. This distinction lies at the heart of why human cognition is the central objective.

Cognitive War is the application of targeted and tailored messages and nonviolent methods used against civilian and military decision-makers or the general population of a target state to gain a positional advantage in the cognitive domain or gain desired political, military, and informational outcomes.

While Cognitive Warfare is not new, there are a number of novel technologies that significantly enhance the reach and efficacy of activities that target the way decision-makers and individuals think about a crisis situation. Some have seen this as social media-based influence operations.[9] These technologies can be combined to “assess, access, and affect the cognitive space.”[10] While our competitors think in terms of systems and confronting and deceiving us, Western militaries orient on hardware, maneuver platforms, and kinetic operations.
