Inside Britain’s cyber battlefield of the future as AI reshapes fighting

Dawn had just broken over California’s Mojave desert but the heat was gathering and turning the distant mountains into a trembling blur. Dust clung to boots, weapons and vehicles. The air smelled of diesel, scorched earth and hot metal. Then a British soldier stepped from a concealed position with a small controller in his hands. Above him, almost invisible, an unmanned aircraft circled. On a screen below, enemy positions appeared as moving dots and live images. Coordinates were passed. Targets were confirmed. Seconds later, munitions fell behind hostile lines in ground too dangerous for any soldier to reach. Sirens signalled a direct hit and casualties. Survivors dropped to their knees, tightening tourniquets around wounded comrades and carrying out emergency treatment in the dust. Before they had finished, driverless trucks and desert buggies were surging across the battlefield carrying water, ammunition, equipment and reinforcements. No drivers. No pilots. No shouted orders carried down a trench. The Mirror joined British and allied troops at the US Army’s National Training Centre at Fort Irwin to witness the wars to come – in which artificial intelligence will watch from above, sift intelligence, guide vehicles and determine where and when troops strike. The machines may not yet be in command, but they are becoming the eyes, ears and nervous system of the battlefield. This was Project Convergence-Capstone 6 (PC-C6) involving the Five Eyes alliance of Britain, the United States, Canada, Australia and New Zealand. In temperatures up to 49C, soldiers tested how they would fight an enemy armed with drones, cyber weapons, signal jammers and AI systems. The familiar image of troops advancing behind tanks while commanders study paper maps is being overtaken by something faster, more connected and potentially more deadly. A drone can spot a target beyond the horizon. AI can examine streams of video, intercepted signals and battlefield data in moments. A commander can launch a strike before an enemy realises it has been found. The aim is to compress decisions that take hours into seconds. Yet senior officers insist that the machines are not being allowed to choose who lives and dies. None of the gear being tested was fully autonomous, according to Colonel Jim Howard, commander of the British Army’s Experimentation and Trials Group. He told the Mirror: “You allow AI to do the science, and the human to do the art. You’re not looking at replacing people, you are augmenting and accelerating people, and giving them the tools to be faster and better, and more lethal.” The machine finds patterns, processes data and points towards danger. The human makes the judgment and gives the order. But the balance is shifting. A soldier may still pull the trigger, yet AI could increasingly determine what they see. Col. Howard said that if an enemy can be located and struck before British soldiers are exposed, fewer lives are placed in danger. But there is another threat. Every drone, sensor, vehicle and communication system depends on software. An enemy that can hack or jam that network could blind an entire force, stop its vehicles or feed commanders false information. A modern army could become almost powerless if their digital web is torn apart. British teams, therefore, attacked their own gear, trying to disrupt signals. Col. Howard said: “All capabilities went through electronic warfare attack and jamming, to see how resilient they are. Some are able to shrug it off – there’s some very clever tech.” At Fort Irwin, up to 60 pieces of gear were pushed through the dust and heat, including acoustic sensors, aerial drones and unmanned ground vehicles. Col. Howard said: “There are technologies in that tent you could buy tomorrow. Others are more emergent and are going to require a bit more work,” British troops were inserted into a US corps-level operation and required to connect their equipment with systems used by all five allied nations. Brigadier Karen Peek, the UK task force commander for PC-C6, said no country could face the emerging threat alone: “It is more complex than ever, and technology is evolving at a rapid rate. Making sure that we train as we would fight is really important.” Fighting an enemy they cannot see or hear, armies that cannot communicate or move quickly enough may be destroyed before they know what is happening. Yet Brig. Peek said the most important achievement was not found inside any tech: “This exercise is about way more; it’s about people, and building that trust. The allies are learning, adapting, innovating, and we are much more ready now for future challenges.” The soldiers remain at the centre of the fight. They still carry the weapons and make the final decisions. But all around them, largely unseen, AI is already beginning to dominate the battlefield.
