Ukraine is currently at the epicenter of radical changes taking place in the way modern wars are fought. However, much of the world is still busy preparing for the wars of yesterday. European armies are only combat-ready on paper, while the invincibility of the United States military is based largely on past victories.
The current state of affairs is far from unprecedented. In early 1940, Polish officers tried to warn their French counterparts about Nazi Germany’s new blitzkrieg tactics but were ignored. France surrendered soon after. There is still time to adapt to the transformations that are now underway, but the clock is ticking.
One of the key lessons from the war in Ukraine is the evolving role of soldiers. People are now the most expensive, vulnerable, and difficult resource to replace on the battlefield. Meanwhile, many of the core weapons systems that dominated military doctrines in the late twentieth and early twenty-first centuries are becoming less relevant. Tanks, artillery, and other traditional systems are simply too expensive and are unsuited to the challenges created by newer technologies.
Unmanned systems of all kinds have emerged since 2022 as a fundamental element of modern military doctrine. This is radically changing everything from the structure of armies to the role of the individual soldier. Remotely controlled equipment no longer needs a large crew to support it, while individual models are becoming more compact and maneuverable. As a result, the power of unmanned weapons systems is increasing exponentially, while production is expanding to industrial scale and becoming significantly cheaper.
More and more soldiers now serve as unmanned systems operators. Those who remain in more traditional roles perform tasks such as special operations, guard duties, or logistical functions. The war being waged by Ukraine has demonstrated that the modern battlefield features a kill zone up to 25 miles deep and spanning the entire front line. This zone is controlled by drones that destroy any infantry or equipment. Combat operations are increasingly conducted by drone operators located deep in the rear or in underground bunkers.
In these conditions of drone dominance over the battlefield, any attempts to stage major breakthroughs are doomed to failure. Instead of tank columns and artillery duels, offensive operations require maximum dispersal of forces and the greatest possible camouflage. The main task of troops is to gradually shift the kill zone deeper into the enemy’s rear.
Success depends upon the ability to rapidly produce large quantities of inexpensive combat drones and continually update their control systems. Initial tactics involving single drones and individual targets are already becoming a thing of a past. Instead, operators can now use artificial intelligence to control entire fleets featuring large numbers of drones deployed simultaneously. This approach allows a single soldier to manage kilometers of front line space rather than just a few hundred meters. The result is a reduction in the need for mass mobilization and an emphasis on the professionalism and technical skills of each operator manning the front.
Combat operations now boil down to two main scenarios: Either the collapse of an enemy who is not prepared for the new intensity of combat, or a positional struggle in the style of World War I. In a protracted positional war, it is crucial to ensure control over the kill zone and maintain sufficient supplies while depriving the enemy of similar capabilities. The protection of logistics networks and the infliction of maximum damage on the enemy’s rear areas is of decisive importance.
First and foremost, this means cutting off ground supply routes. To protect logistics, armies must develop fleets of maneuverable transport drones that are not dependent on road quality and can navigate minefields. Meanwhile, to ensure the steady supply of ammunition and spare parts to underground storage points along the front lines, a mobile air defense system featuring interceptor drones is necessary.
At the strategic level, key targets are now weapons factories, logistics centers, and command posts, which are often hidden deep in the rear or located inside underground bunkers close to the front lines. Destroying these high-value targets requires guided missiles or other air strike capabilities. Military planners are therefore faced with the challenge of moving away from expensive manned aircraft toward reusable strategic drones.
Testing of fully-fledged unmanned aircraft is already underway. The transition toward unmanned aviation will open up the mass deployment of guided aerial bombs, which are significantly cheaper than missiles. In addition, strategic drones will themselves be able to act as “aircraft carriers” for kamikaze drones.
The same principles apply equally to the maritime theater of operations. Ukrainian Sea Baby naval drones have already proven themselves by destroying numerous warships from Russia’s Black Sea Fleet and carrying out attacks on Russia’s shadow fleet of oil tankers.

To ensure their future national security, states must focus on the mass production of unmanned systems and their components. China currently accounts for the lion’s share of component parts. This is a challenge for any country that seeks to play a role in global affairs. China must be deprived of the strategic advantages it enjoys due to its status as the leading producer of components for unmanned systems.
Many NATO generals appear to think that recent technological advances are making war cheaper and creating a more level military playing field. This is a mistake. In reality, any reduction in the cost of weapons is more than offset by the need for increased quantities.
It is also important to stress that unmanned technologies alone are not enough. Another key factor is an army’s access to reliable digital communications similar to Starlink. Without this capability, it is impossible to coordinate combat operations, collect data, and maintain connections between individual units and command structures. It is no coincidence that China is already investing billions to address this issue.
The transformation currently underway in the military sphere also increases the role of cyber warfare. Disruption to logistics, power outages, and communications breakdowns can all provide the enemy with the opportunity to advance. A hacked cyber system can expose vital defenses or dramatically reduce the possibility of recovery.
Looking ahead, technological innovation in the military must be recognized as a national priority when allocating defense budgets. This applies to everything from unmanned systems to the development of artificial intelligence.
The most important revolution must take place within the minds of today’s military generals. A comprehensive rethink of existing military doctrines is currently needed. Armies must be completely re-equipped. It is time for the top brass to acknowledge that they should either change or give way to a new generation of military strategists.
Ukraine’s experience since 2022 has confirmed that in order to be successful in modern warfare, armies should model themselves on technological giants like Amazon and SpaceX. They must embrace flexible thinking and be capable of competing in terms of implementing new innovations.
In an era of accelerated military change, all countries face a simple choice of adapting or accepting the inevitability of defeat. The winners will be those who embrace the lessons from the technological revolution currently underway on the battlefields of Ukraine.
