Someone here said "[Russian] tactical units", "smoke grenades". They must be joking.
A drone like this is defending against 2-3 50-year-olds without military experience wading through a bombed out tree-line into almost certain death, because there are literal firing squads waiting if they don't. With a huge round like 12.7, all you have to do is fire pot shots in the general vicinity while drone pilots do the rest. Also, these can be life-savers for an outpost when weather conditions ground all drones.
This is a fluff piece, but these machines might become very real very soon. They're already used for resupply and dropping mines. We have plenty of videos of that from both sides. A few months ago we had a video of one of these taking out an infantry carrier. This is not vaporware. It's a bad approach at worst, but I wouldn't be surprised if this grows exponentially for many years to come.
You are being dishonest. Those squads usually have SOME degree of drone, artillery and aviation support behind them. They are basically there to find out where the defenders are. Sure they are expendable, but they are just a part of the attack. I bet 24 hours sitting in a trench with FPVs, 152mms, and FABs exploding all over your position would change your mind as to the danger posed by those attacks you make fun of. Being at exactly this location vs kilometers away while remotely controlling a mobile gun turret makes ALL the difference
At this point might as well just play strategy video game and call it a day?
Both sides staring at screens, controlling drones fighting each other.. why use physical drones at all? abstract it away and play video game?
In the near future, war might be about who can build faster/better and hit the other economy more effectively, and those who can't produce any more drones, lose.
If you think about, we moved human one-on-one battles to MMA and combat sport, this allowed channeling individual human aggression in a controlled environment. The future war might be not very different, swarm of drones fighting other swarm of drones while others watching on the news, who can build, manage and deploy smarter and more effective drones. If one side economy collapses and their manufacturing collapse, then what is left? they could easily kill the people, but other nations won't allow it, so it will stop at economical defeat.
We (as humans) are getting more strict about losing people's life. We don't allow genocide, we don't allow colonization and enslavement, at least the majority of nations agree that this is not acceptable.
So it is NOT like before. And the logical conclusion, as those drones get better and more widely adopted, is that war will be nothing more a video game with real economics and supply chain. So we basically made the cost of genocide or colonization too high to absorb. Previous wars, people got away with it.
The majority of nations? majority of people on earth? We are going to a multilateral world and to win a war you need secure the appeal of majority. If the majority think your war is illegal they can cut you off from the world economy.
It is a distributed consensus-based algorithm, and the young people who are writing those algorithms will shape the future of governance.
You either agree or disagree with the idea of genocide. And if you disagree with idea of genocide, then this is becoming closer to video games as more drones are deployed which is my thesis. But if you agree with the idea of genocide, then yes, wars can be won by total elimination (or major reduction) in the other people's population and loss of life.
So do you think genocide is acceptable in war or not?
Orignal Star Trek did an episode on this - "A Taste of Armageddon". The war was a video game - fought on a computer. But if the virtual bombs hit your area, you were declared dead and had to a report to a disintegration chamber. If you can get past the dated special effects - the concept is the same.
The difference is you can appeal or ignore a game result. If Ukraine lost a strategy game tournament, would they give up their territory? Or fight to hold it still?
> In the near future, war might be about who can build faster/better and hit the other economy more effectively
This has been the assumption for over a decade now.
> those who can't produce any more drones, lose
Already the norm. Even the Taliban has been operating a drone mass production program for a couple years now [0][1].
> If one side economy collapses and their manufacturing collapse, then what is left? they could easily kill the people, but other nations won't allow it, so it will stop at economical defeat
This abstraction of warfare isn't as peaceful as you make it out to be. Operationally, you still need to take out dual use infra which in a number of cases is civilian in nature.
The reality is, countries have increasingly accepted that civilian casualties will occur and it doesn't matter because they don't impact tactical goals.
Yes, but what you are missing the cost of total elimination of the other side.
For example, in Iraq, Saddam was able to use chemical weapons and wipe out the resistance, this is no longer an accepted solution by majority of people on earth.
So there is no real way to actually win a war. If you can't kill or enslave the other population, and the world is not accepting refugees, if you hit one economy completely you might the global economy. So what do you do? there is actually no real way to win a war as those constraints become strong and stronger. You are left with the only option of nulling the other's economy down and hope they would resign, by better co-ordinating your drones and managing your economy, which is a video game in the real world.
> You are left with the only option of nulling the other's economy down
How do you (detest this phrasing, it very glib) null the other side?
Most weapon systems aren't developed in entirely separate supply chains - they use off-the-shelf components that are available for commercial usecases as well.
To successfully take out an opponents operational capacity when they are using dual use technology means the barrier between "civilian" and "military" is nonexistent.
It basically means the return to total war doctrine.
Reading between the lines of the article it seems advanced but not too surprising.
I assume that at night when it "withdrew to a covered location" there was opportunity for maintenance, battery swaps, etc.
The article says that it successfully carried out "multiple calls for fire." That sounds like over those 45 days there were multiple missions to provide suppressive fire. They're not explicit about what that means but it sounds like, "if you see anything moving in this arc, take a few shots at them". Presumably there's some AI to prevent it from wasting ammo on really dumb decoys.
A "simple" mobile automated turret has been around for a while. The novelty they would be demonstrating is essentially battlefield robustness. They aren't claiming that this machine can operate completely autonomously for 6 weeks but the incremental pieces are still hard.
“It occurred to me that if I could invent a machine - a gun - which could by its rapidity of fire, enable one man to do as much battle duty as a hundred, that it would, to a large extent supersede the necessity of large armies, and consequently, exposure to battle and disease [would] be greatly diminished.”
― Richard Jordan Gatling, 1877
But imagine the efficiencies to be gained if you swapped out the direct human operator with an automated operator. Then, you can have teams of automated operators being operated by a single human!
They are. EW and IR C-UAS has been productionized over the past decade in most countries, but there are still supply chain and cost blockers around power electronics and they tend to be treated as a last resort because of their indiscriminate nature.
This is surely the future. At some point we will eventually have battles fought entirely by pilot(less) drones? And then war becomes purely economical.
One of my favorite fun facts is that it’s nearly impossible to get a hamster drunk - their foraging method is to get, eg, grains and fruits and store them piled up underground in their burrow, where they of course ferment, so hamsters’ livers have become unreasonably good at metabolizing alcohol.
I haven’t heard “dead man zone” (although I don’t really engage much with military stuff so maybe it is just an expression I’m not familiar with).
I think “no man’s land” is a pretty popular and similar expression. Out of curiosity, did you translate “dead man zone” from another language?
I just find it interesting because it seems conceptually similar but much bleaker, so if it comes from, like, French or German or something maybe it reflects an even bleaker WW1 experience.
It's the space between trenches. I've been watching a WW1 chronological documentary where they use it, but it's also been said in various ways, as you say.
Nice marketing pitch. In reality it was probably parked at an empty crossroads 10 miles behind the frontline, taking potshots at "suspected" enemy positions.
Why are talking about something you have no idea about? There are multiple videos of this system engaging in combat missions. There are first-person videos from them accompanied by footage of recon drones flying above them. And some of those videos are from last year already.
I think you could just ship generic robot dogs in a container and have local contractors straw-purchase firearms, 3d-print cradles, and combine them. None of the contractors would need to know what they were doing.
This smells more like military propagand, i.e., bullshit.
There is no way this is honest or real, i.e., it somehow fought off a tactical unit trying to take the frontline that this drone was holding? Or was it just parked in some area where there was no tactical point of even taking the territory?
Just by virtue of its nature, a single drone and/or a well placed dumb grenade, not even to mention likely a smoke grenade could have easily defeated this thing within seconds of deployment if there was any interest in taking the area this toy was "controlling".
Someone is doing a literal con job to get military graft and fraud contracts.
AIUI, a current common tactic for the Russians is sending many small groups of untrained "solders" out probe the front lines and try to penetrate undefended spots. They take a ton of casualties, but some make it through, and they gradually build up, and then try to take action.
Perhaps it would be helpful to view the claims of this article through a cost/benefit analysis?
Clearly if the opponent had wanted to defeat this vehicle and take this ground, they could have.
That said, it seems likely that this vehicle substantially increased the expected cost of taking this ground, and it did so at very little cost/risk to the defenders.
This sort of device dramatically changes the equation of conflict. It seems this article does a pretty good (though unverified) job of making that case.
There are real videos, even months old of exactly these 'land drones', equipped with good ol' .50 cal. In certain situations, they fought extremely well given no risk for crew. I mean killing off entire bmp-something transport including all crew with AP rounds, typically during night since it has night vision, zoom and so on. Verified also by drone flying nearby.
Now I am not claiming all the facts stated in the article are verified by me, but I can imagine one of them got so lucky with drones and getting hidden from their view for prolonged time it could theoretically pull it off. Not sure about batteries/fuel/ammo part thought.
Yes propaganda and bullshit, but by way of exaggeration and puffery, not lying.
I wouldn't expect even a lightly informed mid-wit to think that this murderbot held the ground by itself; and I don't think the author expects that either. Thus something else is probably going on. To wit - puffery.
The murderbot is remotely operated, so it did not held the ground by itself, though it is claimed that it might be able to do some things autonomously.
The article calls this a "Ukrainian unmanned ground vehicle armed with a machine gun" and the headline calls it a "Ukrainian Combat Robot". Not a "drone" like the submitter's title has.
Edit: it seems like the creator calls it a "droid". Is that just them, or is that becoming standard terminology for a kind of ground-based "soldier-robot"? See:
The <title> tag is "Ukrainian Drone Holds Position for 6 Weeks". OP probably hit the "fetch title" button or copy-pasted from a chat app embed when submitting.

What happens when one side wins? In the real world, they actually win. In the video game, nothing happens

In other words, in the near future it might work the exact way it has always worked.

Your ideas are based on the idea of winning in a closed-system game. War is waged by people. Some people actually want the other people to die.
Yes, but it not like before.
We (as humans) are getting more strict about losing people's life. We don't allow genocide, we don't allow colonization and enslavement, at least the majority of nations agree that this is not acceptable.

We don't allow? Who doesn't? And what are they going to do about it?

It is a distributed consensus-based algorithm, and the young people who are writing those algorithms will shape the future of governance.
If you downvote me then you are advocating for the old way, which is genocide.
What made you come to that conclusion?
You either agree or disagree with the idea of genocide. And if you disagree with idea of genocide, then this is becoming closer to video games as more drones are deployed which is my thesis. But if you agree with the idea of genocide, then yes, wars can be won by total elimination (or major reduction) in the other people's population and loss of life.
So do you think genocide is acceptable in war or not?
who doesn't allow genocide nowadays, exactly? or rather who intervenes to stop it? they don't seem to be very quick.
A disrupted global consensus-based algorithm.
Finally, my years of playing Starcraft have real-world use! Also: Everyone will soon bow to S. Korea :D

Interesting, need to watch that.
So like the old League of Legends lore before their Institute of War retcon?
> At this point might as well just play strategy video game and call it a day?
No.
Young men being slaughtered in their hundreds of thousands.
Not a game
The difference is you can appeal or ignore a game result. If Ukraine lost a strategy game tournament, would they give up their territory? Or fight to hold it still?
Yes we are not fully there yet, but we are getting there.
We are seeing the transition right in front of our eyes.

I believe the movie Aliens (1986) has one of the best movie uses of auto turrets.
I’ve been wondering when modern battlefields would get Team Fortress 2 sentries.
When French start supplying Spies.
But how it was not destroyed by flying Russian drones? Did it shot them down? Or did it have some anti-drone support unit helping it?
I have an educated guess.
Flying drones are lethal, but fairly random. Attacking a point target, which will have anti-drone support, is not what they are for.
And too cheap for a missile which is the weapon for a point target
We really are trying our best to make Terminator reality aren't we?
Maybe drones will make human soldiers unacceptable in the future.
“It occurred to me that if I could invent a machine - a gun - which could by its rapidity of fire, enable one man to do as much battle duty as a hundred, that it would, to a large extent supersede the necessity of large armies, and consequently, exposure to battle and disease [would] be greatly diminished.” ― Richard Jordan Gatling, 1877
Should write a MIT case study on that in "Bad Hypotheses 101"
If only wars would end when all the soldiers on one side were dead.
If the people fought before they'll keep fighting, even after their robots are gone.
They will certainly make human soldiers unviable. (I draw mostly dystopian conclusions from that prediction.)
Or it will just lead to lopsided massacres like the maxim gun did.
On the plus side there is now quite a lot of drone on drone combat saving people's lives
They are being operated by humans
But imagine the efficiencies to be gained if you swapped out the direct human operator with an automated operator. Then, you can have teams of automated operators being operated by a single human!
There was never any other option, given the direction of progress and basic human nature.
I know I know, but this and that and not me nor you, yet here we are and this is just beginning.
Why is no one using EMP devices against drones?
https://en.wikipedia.org/wiki/Electromagnetic_pulse#Non-nucl...
They are. EW and IR C-UAS has been productionized over the past decade in most countries, but there are still supply chain and cost blockers around power electronics and they tend to be treated as a last resort because of their indiscriminate nature.
A magnet, a conventional explosive, and a coil on a flexible cylinder of polymer film; are power electronics truly necessary for a localized EMP?
Yes. Range, accuracy, targeting, and reducing blast radius matter.
Not sure what else I can say so I'll leave it at that, and will not engage with further comments.
The proportion of videos featuring drones taking out other drones is increasing.
This is surely the future. At some point we will eventually have battles fought entirely by pilot(less) drones? And then war becomes purely economical.
It would start economical and then some side would eventually resort to the meat grinder.
> each evening, it withdrew to a covered location.
Interesting - why?
> each evening, it withdrew to a covered location.
Why? Isn't the advantage that it can stay in a position indefinitely? Does it not have infrared cameras, etc?
My car also held position for 6 weeks during the winter storms
I had a car hold its position for 6 months during the pandemic. It became occupied by rats, which was fun to deal with.
They gathered some apples from a nearby tree, and apparently had set up a hard cider production facility.
One of my favorite fun facts is that it’s nearly impossible to get a hamster drunk - their foraging method is to get, eg, grains and fruits and store them piled up underground in their burrow, where they of course ferment, so hamsters’ livers have become unreasonably good at metabolizing alcohol.
i'm going to write a fawning article about cars standing still
"It takes infantry to hold territory" is still true I guess, but now it's a single operator in a bunker.
Perhaps in the dead man zone, not sure this would work well where there is civilian population.
I haven’t heard “dead man zone” (although I don’t really engage much with military stuff so maybe it is just an expression I’m not familiar with).
I think “no man’s land” is a pretty popular and similar expression. Out of curiosity, did you translate “dead man zone” from another language?
I just find it interesting because it seems conceptually similar but much bleaker, so if it comes from, like, French or German or something maybe it reflects an even bleaker WW1 experience.
It seems like there could actually be a difference between them?
https://en.wikipedia.org/wiki/Dead_man_zone - is related to bush fires but seems like it could apply to a battlefield?
https://en.wikipedia.org/wiki/No_man%27s_land
Something more akin to actually being in "measure" or strike distance vs just contested territory in between?
Edit: Sibling comment I think clears it up https://en.wikipedia.org/wiki/Kill_zone
You can call it whatever you like: kill zone, gray zone, dead zone - everyone usually understands what does it means.

Time Ghost makes awesome chrono documentaries for the major wars. And a ton of mini series on special topics.
But what if it gets hacked by the russians?
Considering the usual behavior of the Russian military, it’ll keep firing at Russian soldiers.
Nice marketing pitch. In reality it was probably parked at an empty crossroads 10 miles behind the frontline, taking potshots at "suspected" enemy positions.

This is on my 2026 bingo card of things that never happened.
Yep, until it hits you.
Maybe it's the ghost of Kiev controlling the robot army? You don't know. But they sure should get a $50 billion contract to make them
So what happens in a few years when a submarine pulls up some miles off US coast and unleashes 100 super-automated drones to terrorize the country?
Heck maybe not even a sub needed, some smaller country could have an automated tiny raft too small to be seen on radar tow in the drones
They could charge via phantom power from powerlines and will find a way around GPS jamming
I think you could just ship generic robot dogs in a container and have local contractors straw-purchase firearms, 3d-print cradles, and combine them. None of the contractors would need to know what they were doing.
Is there some sort of hybrid flying/stationary drone that flys in an sits to hold a ground position?
Common tactic is for drones to wait next to a road and ambush.
Ammunition is heavy.
looks like a treadmill
Not a drone...
How is it not a drone?
Another con job...
Are these the ones controlled by Steam Decks?
These ones by PS5 controllers I believe

Drone is just a generic term.
There are more specific terms for specific types of vehicles, and some of those terms have changed over the past few decades.
UGV = unmanned ground vehicle
UAS = unmanned aerial system
UAV = unmanned aerial vehicle
UUV = unmanned underwater vehicle
Etc
