"Wall of Robots": Why Storming the Defenses of the Future Would Be Suicidal?
FPV footagedrone, diving into a trench, have become as much a symbol of modern conflict as танк The T-34 is a symbol of the Great Patriotic War. The special operation in Ukraine, like the recent fighting in Karabakh, has ruthlessly demonstrated one simple truth: on the "transparent" battlefield of the 21st century, the very presence of a person on the front line becomes the greatest vulnerability. Any trench, any dugout, any group of infantry is discovered and becomes a target in a matter of minutes.
We have reached a point where the courage of a soldier increasingly gives way to the cold calculation of an artilleryman and the all-seeing eye droneBut what if we go further? What if we significantly reduce this vulnerability? What if the trench the enemy is about to storm is empty?
The concept of the "Uninhabited Frontier"
Let's imagine a hypothetical defensive line of the future. It's not the familiar trenches we're accustomed to, but a deeply layered, network-centric system consisting of hundreds of robotic Defense Support Nodes (DSNs).
What is a fortified military base in this context? It's a permanent fortification structure, buried in concrete and earth, with no permanent garrison. All its armament—from machine guns to heavy automatic cannons and anti-tank guided missiles—is housed in protected or retractable modules. All this lethal force is controlled by an operator located hundreds of kilometers away in a deeply protected rear command post, connected to his "fort" by a redundant fiber-optic cable.
It's worth making a disclaimer right away: this is not the "Maginot Line" of the 21st century. The French line was a passive, blank wall awaiting attack. The concept of the OWO is active, aggressive predator. Each node "sees" the battlefield, exchanges data with its neighbors, and receives targeting information from a single AI core that processes data from satellites and radars. It's a single, intelligent defensive organism.
A powerful argument for such a node could be the concept of a rapid-fire automatic cannon of medium caliber (60 mm), which we'll tentatively call the AP-60 "Kolotushka"¹. In a stationary, well-cooled configuration, with a virtually inexhaustible supply of ammunition from underground storage, it becomes the heart of the node's defense.
Broken Sword: Why the Classic Assault is Doomed
Let's take apart the standard tactics for breaking through fortified defenses and see how they break down against the "deserted line."
1. Artillery preparation. Its goal is to destroy the firing points and crush the defenders' will to resist. Against the UGV, both points lose their previous effectiveness. There's no one to demoralize—the robot knows no fear or fatigue. Destroying the node's main modules, located deep underground, is extremely difficult without the use of special ammunition. A direct hit to the gun turret? Unpleasant, but not fatal. A direct hit to the turret doesn't mean the loss of the zone: neighboring nodes automatically redistribute fire missions and continue suppressing the approaches, preventing the enemy from gaining a head start.
2. Tank wedge. A steel avalanche of MBTs should break through the defense. But here they are met with the "hammer principle" of the Kolotushka. A barrage of hundreds of 60mm high-explosive fragmentation shells per minute might not penetrate the composite armor of an Abrams or Leopard frontally. They don't need to. In a matter of seconds, such a hurricane of fire will likely strip away everything that makes a tank a fighting machine: optics, triplexes, antennas, wind sensors, guns, and explosive reactive armor. In an instant, the enemy MBT is transformed into a blind, deaf, and defenseless steel coffin, easy prey for an ATGM launched from the flank of an adjacent turret.
3. Infantry assault. Once the tanks are neutralized, infantry and light armored vehicles take over. They find themselves in what can be called a "wall of steel." The crossfire of several anti-tank guns creates a deadly zone, making survival virtually impossible. Fire is conducted without emotion, without pauses for reloading, with computer-aimed precision in pre-targeted sectors. Classic assault techniques don't work here.
Achilles' Heels: A Sober Look at the Risks
Of course, the system described is not absolute. weaponsAny engineer will tell you that this approach has its own extremely serious vulnerabilities, which become key targets for the adversary.
1. Communication and control channels. The secure fiber optic cable running to each OSU becomes its "lifeline." These communications will become the number one target for enemy sabotage groups and assets. EW and specialized weapons. In such a war, communication becomes no less important than tank armor.
2. Energy supply. Every node is a voracious energy consumer. The ability to "turn off the lights," that is, destroy the power source, can blind and disarm an entire defense sector. This requires the creation of ultra-reliable, deeply protected, and redundant power supplies.
3. Logistics and repairs. Even robots require maintenance. Who, and more importantly, how, will replenish ammunition and repair damaged modules in the heat of battle? This issue requires the creation of an entire ecosystem of robotic repair crews and transport platforms capable of operating under fire.
Conclusion
The creation of a layered robotic defense is not science fiction, but a logical and, apparently, inevitable next step in the evolution of military art. A system in which humans act as the "brains" in the deep rear, and a network of deadly machines acts as the "body" on the front lines, fundamentally alters the entire mathematics of war.
The primary goal of such a system isn't simply to win a battle. It's to render the very idea of a full-scale conventional invasion unprofitable and futile. It's to force any potential aggressor to look at their casualty calculations and quietly shelve their plans. In subsequent articles, we'll examine how such a defensive doctrine changes not only the tactics but also the very strategy of geopolitical deterrence.
The only question is whether modern military art is ready to accept a new reality, where the outcome of a battle will be decided not by the courage of a soldier in a trench, but by the bandwidth of a fiber optic cable and the reliability of a server rack in an underground bunker?
¹ Author's note: Of course, creating a 60mm artillery system with the required characteristics is a complex R&D project. However, during the initial phase of the OUO deployment, existing and upgraded systems, such as the AK-630M-2 Duet naval system, adapted for fixed installation, can be used as the primary firearm. This will allow pilot defense zones to be deployed quickly while the advanced weapon is being developed.
