[Science Column] Computation Outpaces Gunfire: How Algorithms Are Redefining the Grammar of Modern Warfare

The grammar of war is changing. We are entering an era where algorithms, not the sound of artillery, determine victory or defeat. Invisible to the human eye, infrared sensors relentlessly track targets, while in the tumultuous sea of electromagnetic fields tangled by jamming and spoofing, unseen coordinates collide.

While wars of the past were decided by the amount of gunpowder and the thickness of armor, the future warfare now witnessed in the Middle East and Eurasia has transformed into a battle over who possesses faster computing chips and whose data can be maintained without interruption and with greater accuracy. The language of the battlefield is no longer the sound of gunfire, but the speed of judgment compressed by algorithms.

The most symbolic scene in this war is not stealth fighters costing billions of won, but the proliferation of low-cost drones, each worth merely hundreds of thousands of won, piloted in first-person view (FPV) as they sweep through enemy lines. In an interview with CBS, former CIA Director David Petraeus remarked that “drones are the heartbeat of the battlefield” in Ukraine-a statement with profound implications. Drones are no longer secondary tools; they have become the very “command-and-control ecosystem” where surveillance, identification, and strikes are integrated in real time.

More importantly, weapons are now being "updated." In the past, once weapons systems left the factory, their performance was fixed hardware. Modern drones, however, evolve on the battlefield in real time. If the enemy neutralizes a drone by jamming a specific frequency, engineers can update the communications algorithm and redeploy it within just a few hours. As the center of gravity in warfare shifts from manufacturing to software engineering, weapons are no longer finished products but continuously evolving “programs.” Now, victory is determined not on the factory floor, but at the developer’s keyboard.

The fiercest battles in modern warfare are now fought in electromagnetic spaces beyond the reach of human senses. Tactics that jam GPS signals or inject fake signals erase maps from the skies, turning precision-guided weapons into “blind arrows.” Yet, science and technology provide alternatives to fill these gaps. Visual odometry-matching terrain from camera images-and inertial navigation systems (INS) allow machines to navigate independently, even without external signals. In skies left open but stripped of coordinates, machines draw their own maps and advance on their own.

At the same time, traditional tactics of “concealment” are also rendered ineffective. High-sensitivity infrared sensors and AI noise reduction technologies can read even minute traces of heat through dust and smoke. Soldiers’ body heat, engine residual warmth, and even the faint warmth of underground bunkers are all reduced to data. The Center for European Policy Analysis (CEPA) describes this as “invisible electromagnetic fields becoming the new terrain.” The battlefield has become as exposed as a transparent aquarium, thanks to advances in semiconductor technologies such as low-noise amplifiers and high-speed image processing chips. Now, “hiding” requires not only physical shielding but also erasing electromagnetic and thermal signatures-a competition of high-level technical prowess.

The neural network of war is now the low Earth orbit (LEO) satellite communications network. Even amidst the ruins where ground base stations are destroyed, drone footage and target coordinates are shared in real time via satellites. By reducing the latency of conventional satellites from hundreds of milliseconds to just tens of milliseconds, pilots on the other side of the globe can control weapons as if they were present on the battlefield-creating a “real-time battlefield.” The decisive factor in victory is no longer the destructive power of gunpowder, but the uninterrupted speed of data transmission.

With the addition of AI-based target recommendation systems, the concept of time in warfare is further compressed. The process that once required commanders to contemplate for tens of minutes over a map is now decided in an instant through sensor fusion and model inference. Israel’s AI systems “Lavender” and “Habsora” exemplify this trend. The Guardian has reported that AI-based target recommendation systems have accelerated the pace of airstrikes far beyond what could be achieved by human review. The problem is that such overwhelming efficiency risks reducing human judgment to a mere act of “simple approval” of the machine’s calculations.

Modern information warfare has become even more sophisticated with the advent of generative AI. Deepfake speeches, manipulated images of battlefield situations, and automated bot accounts now sway not only enemy states but international public opinion as a whole. This goes beyond mere distortion of information, reaching the level of “cognitive warfare,” where belief and fear are artificially engineered. War now extends beyond the advance of tanks to a struggle over how to corrupt the very emotional structure of the opponent.

All these technological advances ultimately rest on semiconductors. From the control chips inside drones to the server-grade GPUs powering AI computations, every act of war is executed atop silicon chips. The outcome of future wars will hinge not on the amount of gunpowder, but on the accuracy and survival of data. The core of missile interception systems also depends on computational power that can calculate incoming trajectories faster than humans ever could.

Science and technology have made war more precise and efficient, but at the same time have thrust humanity into unprecedented moral dilemmas. Algorithms calculate only for efficiency and remain silent on the tragedies their results may cause. As technology surpasses human judgment in speed, what final bastion must we defend on the battlefield?

Ultimately, what matters more than the performance of the chip is the ethical will of humans to continually question and scrutinize the decisions made by those chips. We are now witnessing the age of cold algorithms operating behind the sounds of gunfire and explosions. While the language shaping the form of war has already become scientific and technological, the ultimate responsibility to control its tragedy still rests with humanity. Now, more than ever, the wisdom and sense of responsibility of humanity are desperately needed to ensure that technological progress does not only serve to increase the efficiency of killing, and to vigilantly oversee this “algorithmic war.”
