Yes, the rifleman’s day really is over. Errors abound on many levels of analysis and argumentation on this topic; I’ll respond to some here in stream-of-consciousness fashion.

So here’s the first: “Humans will always need to take and hold ground.”

War is not the taking and holding of ground. It is the organized use of violence to impose political will on the enemy. Taking ground is merely one of the means of war, not an end. We did not need to conquer the Japanese mainland to bring them to their knees in WW2. And where war does involve taking ground, robots are well suited to the task.

Already in Ukraine, near-front casualty evacuations and logistics are primarily conducted via drones, ground is sometimes held by drones, and occasionally assaults are conducted entirely by drone. Where the adversarial element is stronger, the progress in automation is slower but nonetheless inexorable. Drones replacing humans on the front is inevitable - at least, insofar as such a front even exists. It’s not a given in war that taking and holding ground is even necessary to begin with.

In fact, throughout history even large ground campaigns often did not involve direct fighting, and where they did, the object was often not to seize a piece of ground (except in relation to where the enemy army then posted itself). See B.H. Liddell Hart’s work, Strategy: The Indirect Approach. The Byzantine general Belisarius often maneuvered in such a way as to merely threaten the use of force, discouraging his enemy from continuing on campaign. Napoleon sought decisive battles, but with his object to shatter the enemy army and national will, not to seize fortresses or cities.

In naval warfare, we no longer need to come face to face to exchange cannon fire, let alone commence ship boarding. And in an air war, pilots do not board each other’s aircraft or need to capture each other’s runways. What happened at sea and in the sky will transpire on the earth as well. It has merely taken longer, since the earth is a denser, slower-moving fluid than air or water, and therefore provides more opportunity for concealment and cover. As ships and aircraft became over-the-horizon assets strike assets, so shall the individual soldier on land.

A geometric analysis yields much the same parallel. As each side’s basic weaponry begins to eclipse the other’s territory, human maneuver becomes irrational. Assume both you and your enemy have 200km of max effective range, and you want to hit something 50km deep into enemy territory - of course you would balk at orders to proceed to within 50km of the “front” yourself if you could stand off from 150km and achieve similar effects. In fact, as you advance, you increase your exposure to enemy teams superlinearly (every time you advance 10km, you add exposure to a widening circular sector of 10 more km across), assuming the front is perpendicular to your line of advance and the enemy has such 200km teams evenly distributed through their depth. When you advance and are spotted, you light up on the enemy’s digital Common Operating Picture (“COP”, like Ukraine’s Delta system), and every bloodthirsty drone team within range will try their hand at hitting you. There is no point at which you break through the enemy’s line and can begin a turning action - you are simply lost deeper in a sea of distributed drone teams the further you go. (As an aside, we may compare this to the experience that the Mongols faced trying to penetrate into central Europe after sweeping through eastern Europe: every hill all the way to the Atlantic was topped with a small but nearly impenetrable castle bristling with crossbows and its contingent of knights ready to sally out and harry the invader, with ready mutual support from neighboring fortresses - only now, imagine there is no need to sally, and every castle within a couple hundred kilometers can also engage in simultaneous attacks with over-the-horizon crossbows) Under such conditions, the “front” as a linear concentration of direct action forces dissolves into a distributed kill web, the so-called “gray zone” that has been gradually forming in Ukraine and will continue to deepen. What happens when the gray zone is an entire nation, an entire combat theatre, or the entire world?

Another change in land warfare that parallels past change in naval warfare is the increasing dispersion at all echelons. This is not merely due to increased destructive payload deliverable to a given area by a given team, which would drive dispersion from a defensive standpoint (standoff, on the other hand, is indeed driven by defensive considerations, as explained in the previous paragraph). Actually, the small drone team does not by itself deliver more destructive energy upon a target than a legacy infantry fireteam or artillery crew. Rather, dispersion is driven by the evaporation of offensive restrictions: the increased ability to coalesce fires at range, organically or on command, together with their already 1-2 orders of magnitude greater range and enabling technology (sensors, COP, AI, delegated authority, satellite comms, etc.) mean that small independent drone teams naturally disperse widely given pre-existing defensive considerations. This historical trend, seen at least since gunpowder overtook cold steel, is now accelerating in runaway fashion. The logical extension is that the human soldiers that make up drone teams will eventually distribute throughout the entire territory available after considerations of a noncombat nature (for example, jurisdictional or geographic) are accounted for. What room for riflemen or tanks is there in such an amorphous mode of warfare? How in the face of all the above considerations can massed infantry or armor even safely reach a collection point to begin transit to an assault against an ephemeral foe?

Returning to the larger debate, what I must say here is that those betting on the rifleman as opposed to the drone are like those who stood in the way of the aircraft carrier in favor of the battleship. The debate has reached its fever pitch, and like in the prior debate, the evident crescendo is itself a leading indicator that the debate is ended. By the time the issue enters public consciousness, it is already decided. Drones and robotics in general are just the physical instantiation of what’s happening in the information space (AI), and those who think either is all hype or a bubble need simply zoom out further on the graph. Once change goes asymptotic, as it already has, an apparent bubble on a long enough timescale is doomed to be lost in the volatility. Those who already possess accurate signal about the issue may confidently leverage information arbitrage in casting their votes, and only if particularly altruistic will bother about the exhausting task of convincing the stubborn old guard. Similarly, by the time the common man realizes a stock is a good buy, he is already too late, and should have bought in years ago. Similarly, the best time to train to be an AI researcher was a decade ago. It is not an accident, but rather the result of a decades-long strategy that the Chinese now have a stranglehold on drone supply chains.

Another pushback: “The ongoing Iran war is a demonstration of the inability of standoff weaponry to achieve victory.”

It is just the opposite. Even Iran’s limited drone scaling (as compared to Ukraine, Russia, or China) has proven to make them enough of a porcupine that we have had to take a step back. From their perspective, they are waging a very effective campaign with what they have, notwithstanding their foolishness in not preparing more (they could have had hundreds of thousands of long-range drones ready, and could have staged some of these to attack data centers and the power grid in the USA). Iran’s limited war goals would have been even better met if they had dissolved their entire legacy military years ago, and focused entirely on standoff weaponry (ballistics and drones). Even in the event of a US invasion and occupation by outdated grunts, short-range FPV drones could easily inflict enough damage to evaporate US public and political support for military action. We are seeing how even the weakened and dispersed Islamist insurgents and militias are able to inflict heavy losses on Israeli conventional forces with fiber optic FPV drones. With Iran’s geography and large population, if they prepared they could hit occupying forces with tens or even hundreds of thousands of FPV drones daily. And if one believes they would lose anyway, as they probably would, they certainly would not perform better by attempting to fight the US with rifles and tanks.

If we decided that we did need to invade, the most effective means would be with a drone-equipped force. Soldiers may still need to carry firearms to protect themselves when they voluntarily move in proximity to masses of people, as when occupying large cities without displacing or slaughtering the populace. But to respond in kind to hostile military or insurgent elements hitting them from tens of kilometers away, the firearms would be useless. Instead, small and flexible formations with organic sensing (radar, acoustics) would need to rapidly respond in kind by finding, fixing, and finishing the enemy with unmanned systems. They would need their own organic interceptor drones as well, to mitigate damage from the enemy. Eventually, all this will take place beyond the human ability to process in real time, requiring every soldier or at least small team to have organic automated counter-drone defenses, like how the Trophy system works for a tank against incoming projectiles - but this is a topic for another essay.

Another objection: “There’s a counter to every new military technology.”

On some level, sure, but the best-known counters to drones are more of the same, both to intercept the enemy’s drones and to attack him directly. Was there some counter to gunpowder weaponry that allowed the knight to continue his reign over the medieval battlefield? No, the knights are all gone, never to return. Their horses, swords, lances, and armor are all gone. At best “cavalry” continues as a loose analogy, for example in reference to mechanized/armored forces or “air cavalry”. The “infantryman” is likewise doomed to be relegated to history, not as the fundamental unit of combat power carrying his equipment on his back and engaging the enemy in direct fires, but continuing only as an analogy or an anachronism.

The most commonly proposed counters to drones typically involve some form of directed energy. Well, why isn’t such weaponry being used widely? The only forms of directed energy being actually commonly employed on the modern battlefield are simple jamming and spoofing. But their effectiveness (which even at peak was never enough to arrest the development and scaling of robotic warfare) is declining with the advent of drones controlled by fiber optic, satellite, or fully autonomous means. The last of those is a permanent escape hatch against jamming now that Pandora’s box has been opened. As for electronic attack meant to cause physical damage to onboard electronics of the drones, this is rarely ever known to be used, since the discouraging economics related to it are so easy to see playing out (expensive to implement across one’s force, but easy to counter with cheap shielding). As for lasers, they are being employed to a limited extent and do offer a decent solution to defending against one or two drones at a time, but also face economic limitations, and are quite helpless against a drone “swarm” attacking in large numbers from multiple angles simultaneously, which must all be engaged in a very limited range and timespan.

What about some wonder weapon at some secret US lab? We haven’t seen it yet, and I doubt that, if it’s out there, it’s cheap and small enough to equip our entire nation’s military with it in the next couple years. Or perhaps it’s some wonder-weapon of an entirely different category - maybe the NSA or some other agency can push a button and shut off China’s power grid or internet overnight. If such capability exists, it’s an argument against us having a conventional military ready for peer-level warfare at all. We would need neither drones nor rifles if we’re really that far ahead. Of course, AI is regarded on some level as such a cure-all weapon, but it’s not there yet. We’d better maintain a military until some hypothetical future where AI alone is the only weapon a human needs.

Another: “If drones are so decisive, why is Ukraine a stalemate?”

As in the case of the Iran war, this makes the opposite point the skeptic expects. Ukraine should not have been able to survive, much less perhaps begin to even win. Human maneuver on both sides has largely ended, and drone technology and doctrine are still unfolding. The next step is to resume maneuver via drones, as various units (Khartia, Azov, etc.) are experimenting with. The rifleman is dead, so what replaces him? Whoever first understands and scales massed combined intra-drone arms and drone maneuver warfare may actually break the tactical and operational deadlock, if the strategic drone campaign doesn’t end the war first.

A final objection: “The experience of war in Ukraine does not generalize. Combined arms maneuver warfare reigns supreme; therefore drones are just one more tool in that combined force.”

Yes, combined arms maneuver, where possible, should produce cleaner victories than the largely attritional warfare seen in Ukraine today. However, the combining of arms and the maneuvering of those arms can be done entirely by drone. Drones can fill every niche and every domain - reconnaissance, armor, standoff fires, direct fires, sea/air/land/subsurface/space, etc. Why on earth would you expose an infantry company or special operations teams by sending them into enemy territory to conduct an ambush when you could have cheap drones do the same? If a drone can fly hundreds of kilometers, what do you gain by pushing the humans launching them forward by ten or twenty kilometers? Drones are already laying minefields, conducting reconnaissance, sitting on roads in low power mode waiting to ambush, and executing logistical and industrial sabotage at a scale humans could never have hoped to accomplish.

Currently, a Ukrainian “mid-range” drone battalion is responsible for achieving effects at a similar depth, about 30-300km, to that reserved for an army corps (two orders of magnitude more personnel) in legacy US doctrine. But unlike the soldiers controlling HIMARS and other centrally directed systems (often now nearly useless due to ubiquitous GPS denial) that the corps used for such effects, the small Ukrainian drone teams that comprise the mid-range battalion are capable of almost fully independent, decentralized operation.

Small Ukrainian teams consistently stop vastly superior NATO naval and land forces dead in their tracks in exercises, and that’s just today; there’s hardly anything left you can do to further refine a rifle or an artillery shell, but robotics and autonomy are just getting started. Yes, the Ukrainians and Russians are deadlocked in attritional warfare, but an opponent with time to plan and scale in peace would not deliberately leverage robotics to enter such a terrible state of affairs. That is, there is nothing fundamental about drones that leads to an attrition warfare bias.

Limitations like bad weather or different terrain are also at worst speed bumps to drone warfare. In the long run, where they haven’t already, machine sensors will of course exceed human senses, not merely in their fidelity but in their resilience to the elements as well. Machine locomotion will handle rough terrain better than any human. Small machines will squeeze in tighter spaces. Machines that do not sleep will dig out and hold fighting positions at lower energetic cost. Those who point to temporary limitations are like those who point to some current deficiency in AI, such as hallucination or need for cooling and powering large amounts of compute - how many people are even aware that AI is already improving itself? Aware that NVIDIA’s latest and greatest chip was designed by AI? How many actual practitioners, who can now do what they never could have hoped to before, still downplay drones or AI? How many naysayers have looked at actual data and drawn out the trendlines? In 2023 Ukraine conducted roughly a hundred long-range strikes a month; two years later it conducts over seven thousand, at ranges out to two thousand kilometers - a seventy-fold scaling, in wartime. Across Ukrainian, Russian, and Western media there is a new fixation with the potential downfall of Russia almost entirely due to the scaling of these effective long-range strikes against industry.

As mentioned in my previous article, the scale this year across all domains of drone is absolutely staggering: 20-40 million drones employed in total this year by Ukraine and Russia, and China likely producing the equivalent of 100 million drones in components and actual finished units. Each of those nations’ militaries is integrating drones all the way down to the fireteam level, replacing swathes of their military structure as quickly as they can. And of course, direction from senior officials of the Department of War is crystal clear that we need every combat soldier to have access to drones, although they haven’t comprehended yet what kind of scale and requirements (range in particular) that notion implies, or how it will revolutionize doctrine rather than change it incrementally.

EDIT 07 AUG 2026: Based on feedback, I’m seeing that I may have been encouraging a category error by my framing, which is along the lines of: Unmanned military equipment is another monolithic entry in the set of tools including rifle, mortar, tank, aircraft, etc.; and therefore its expanding use is to the exclusion of those aforementioned tools. I understand how such a framing could close off discussion, so let’s try a different approach:

A better mental model encapsulating UXS is to see “unmanned” as an ontological label we can apply across (rather than in addition to) the entire category of legacy military equipment, as well as across legacy formations. An unmanned rifle is a turret or Unmanned Ground Vehicle (UGV). An unmanned mechanized rifle platoon is a UGV platoon. We can have unmanned tanks, artillery, close air support, bombers, fighters, boats, ships, subs, CASEVAC/MEDEVAC, supply trucks, and so forth. Anything a human does in physical space may be done by a robot. We have actually seen legacy platforms, such as old aircraft, retrofitted with servos to remotely operate controls originally designed for humans (which of course is merely a stopgap measure, as it is less efficient than designing a platform to be unmanned from the ground up).

Going unmanned may be viewed on some level as a simple (though powerful) upgrade. If you could make your equipment invisible or indestructible, you would, regardless of whether we are talking about tanks or planes or subs; likewise, if you can make it unmanned, you should, regardless of other labels. On the other hand, once you upgrade the majority of your force to be unmanned, the expected utility of that simple change in aggregate is near limitless.

So when someone says, “we will always need infantry”, an easy answer is, “fine, maybe we will, you’re talking about unmanned infantry.”

Something else worth addressing is this notion that commanders or soldiers need to be near to the action to make sound decisions and employ equipment most effectively. While I certainly believe commanders should forward deploy to experience what their soldiers are, the soldiers themselves that they visit should be always minimizing risk by staying as far from the enemy as possible now that we are in the unmanned era. The arguments on this topic usually revolve around sensors and comms. With respect to sensors, machine sensors are already vastly superior to human senses, and machine intelligence is already vastly superior to humans at sifting through enormous quantities of sensor data. Humans can’t see any better in a blizzard than a weatherproofed sensor can (and even such well-made sensors still cost far less than a human soldier, can be deployed 24/7 at greater scale, and are only getting cheaper and better).

As for comms, it’s only a limitation in the way that fuel and ammo are. Electronic warfare is common in Ukraine because it’s better than nothing, not because it’s a solid counter to unmanned systems. Physics is just not favorable for jamming and spoofing against distant enemy positions, thanks to Free Space Path Loss (inverse square law). As for jamming enemy ISR or strike drones loitering closer to your own position, that capability was never reliable enough to be a consistent defense before, and now autonomy has overthrown it forever. Sure, I may temporarily not be able to receive consistent feed from that particular sensor or be able to directly control it if you really focus your resources against it, but that won’t save you. And of course, every time electronic attack equipment is used, it shows its position like a beacon, which is another nail in the coffin given cost asymmetry between drones and such equipment

"One thing I have been thinking about a lot is the concentration of forces- ironically this new battle field gray zone has made infantry assaults when there is bad weather or strong winds easier as you are meeting fewer defenders spread over an area. So if you figure out C-UAS at scale you can now assault with a greater force against a weaker enemy. Not sure what that C-UAS might be, but IF it exists then again we are back to concentrated assaults with large yields"

I mention weather as a non-issue but maybe it needs fleshed out more. Also once the first couple lines are replaced by ground drones, winds become less relevant. As for C-UAS, again you're only ever mitigating to some moderate extent, because the UAS adapts too. Oh, you can down my UAS from up to 200m with directed energy? Okay, now I start putting rifles or rockets on the UAS. Yes you're right that IF you can mass forces, you are fighting against a less locally numerical foe, but you have to consider the geometry I mentioned in the article - can you really make it to that position, take it, and hold it against hundreds of kilometers of depth of enemy drone operators you just pissed off (and you're now getting pinged relentlessly on their COP until you die)? Can your local C-UAS you brought with you really protect you from all that?

"I just think that from my own studies these things comes and goes. Compare ww1 where the lesson was not to concentrate to ww2 where tanks again could increase protection layers and add speed enough to concentrate again. So something will perhaps be built where c-uas reaches a point where we go back to a very different form of mass and maneuvering."

Thus my recommendation to "zoom out". On a longer time scale, dispersion has greatly increased across sea and land. Now I'm not saying something else revolutionary couldn't upend things. Nothing we've seen so far. I'm talking about bio warfare, micro drones, eVTOL armies, like I mentioned in the Cipher Brief article. Also AI will probably start building disruptive things we can't even imagine.

I mean do you really think that it could go totally full circle? I don't - I can't imagine powered armor or energy shields or something for example ever leading back to melee combat like in star wars or Dune. I think we will just gradually spiral to further and further away combat, since the energies involved just keep increasing in orders of magnitude. And to your point, those energies can always be concentrated, which I think actually drives dispersion/distribution.

"Consider: https://press.armywarcollege.edu/cgi/viewcontent.cgi?article=1251&context=parameters"

"Only by seeing what does change can one deduce what does not", yeah I'd agree with that. Although I'd say very little stays the same from a pragmatic perspective... To be honest, if you really wanted to solve the questions he raises on a deeper level, you need philosophy. Much of what he is discussing boils down not just to the nature of war specifically but of reality in general. Classic questions about the One and the Many, reality as fundamentally teleological vs ontological, etc. are pertinent (i.e. how much is part of reality related to other parts, in space, time, scope, and level of analogy or abstraction)?

"Not agreeing with this, just thought I'd share: Achtung – Drones! Restoring Maneuver, Mission Command, and the Generations of War in the Unmanned Age. Are we willing to build the communications architecture and the command culture that make high-tempo exploitation possible?"

He says we should reduce down to first principles (time, space, force), but then instead of using those particular principles to argue against drones replacing the rifleman, he just asserts new unrelated axioms (first principles) without evidence or explanation or other support: "Drones cannot seize ground. They cannot hold it."... "Those that will have humans at the crucial time at the right place of the battlefield, will be able to grasp the situation in a way drone feeds will never be able to relay". No support offered for these statements. His thesis is basically supported by circular arguments.

I do agree that we need to go back to basics in theoretical terms, which is why in my own article I talked about geometry and such.

"Ukraine has shown that in order to hold ground, you still need a man with a rifle in a foxhole." No it hasn't (he offers no further support/references/explanation), it's just shown that change hasn't fully happened overnight. Ask Andriy Biletsky or Fedorov and they'll tell you infantry is going, going, gone.

"My only complaint is one of phrasing: 'Was there some counter to gunpowder weaponry that allowed the knight to continue his reign over the medieval battlefield? No, the knights are all gone, never to return' The answer is actually yes. For a while armor got heavier and heavier for bulletproofing, though that was a losing game that resulted in the cuirassier wearing pistol proof armor. And of course Vauban's fortifications forced frustrating stalemates throughout the late 17th century. Without even mentioning stuff like winged hussars or british (of all people) cavalry in the opium wars. I would phrase it more as gunpowder's evolution outpaced the evolution of counters."

True, but same idea as with AI/drone "bubble", my answer is to just "zoom out" on the timeline. You're right that my phrasing was poor. Of course I'm well aware of the bullet proof armor stuff, as you're well aware we both are enamored of that era.

"Actually, thinking about it, there's another point to consider there. Part of how cavalry stayed relevant was through artillery fighting itself and locking down infantry. Similarly, is there potential for drone forces to neutralize each other? I think where I struggle, conceptually, is what does winning a battle look like in a drone war? What constitutes momentum, or even just being on the defensive or offensive, assuming peer capabilities? And similarly, how does a drone team operate in aid of a larger effort? Smacking other drone teams and the occasional tank or artillery piece is all well and good, but if you're building millions of drones a year..."

Well, the vast majority of all ISR, all killing, and all destruction of equipment - that is, all battlefield effects - is already done by drone. They are not taking out the occasional tank or artillery piece (there are few tanks left even sighted these days). On that and your other points, I think I'm realizing that the issue is a category error that I myself was feeding into by my phrasing. The problem is that people see it as just another kind of equipment, like a rifle or a tank. That is, the drone is used by a soldier in the same way, and may either supplement or replace that equipment but leaves the soldier himself relatively unchanged. In fact drones are really replacing what SOLDIERS do, not what their equipment does. An unmanned aircraft is an aircraft. Either one is comparable (well, okay the manned one has some limitations the unmanned one doesn't).

Put differently, ALL conventional weaponry that's currently considered manned can be transformed into an unmanned version if it hasn't already been, and then scaled and integrated. If you reduce drones and humans to icons on a map, they're still doing all the same things. They're fulfilling the same warfare functions. You can have drone artillery, drone recon, drone SOF, drone subs, humanoid drone riflemen if you want. But what's unique is that there's no reason to mix humans in with them locally, physically. Humans can have standoff while the drones occupy the "front" such as it is.

So to the questions like "what does winning a battle look like in a drone war? What constitutes momentum, or even just being on the defensive or offensive, assuming peer capabilities?" It could look the exact same if you reduce combat equipment to icons. You might still have armored pushes, ground assaults, hills captured and lost, grand flanking maneuvers, etc - but the humans are back in an underground bunker or city, watching it play out.

I'm not naive enough to think it will lower the human toll. This isn't some optimistic vision. I'm merely describing what current doctrine/TTPs look like when executing by machines rather than biological brains. But of course, I don't really think the present mode of warfare will lift and shift like that. I think we will see even more of the standoff wars (Iran, Ukraine deep strike campaign) in near future. Beyond that, who knows.
