The Army went ashore relatively light

Thursday, March 12th, 2026

Soldier’s Load by S. L. A. MarshallS.L.A. Marshall decried (in The Soldier’s Load and the Mobilty of a Nation) the senseless competition between the armed services in arranging special privileges and comforts for their separate forces when engaged in joint operations:

Consider what happened all too frequently in Pacific operations during World War II! The Army went ashore relatively light even when setting up a garrison operation. Because of the shortage of shipping space the men slept on the ground, with a blanket or so and a shelter half; they cut foliage for bedding. This would all have been tolerable if a Navy or Seabee unit had not set up next door with cots for sleeping, good housing and a ship’s store, complete with free beer. (Though it may have happened the other way, with the Navy taking the spitty end of the stick, I never heard of it.) The soldier compared his own lack of luxury and skinned-down installations with the luck of the people next door. The result was the demoralization of the service which felt itself discriminated against by higher authority, and forced by the country to suffer unnecessary hardship. In the beginning the Army had stuck to the policy of shipping luxury goods only when there was stowage space beyond that required for essential military cargo. It was soon compelled to depart from this sound principle and give shipping priority to welfare goods. The load continued to increase as one service vied with another in trying to make its men feel especially favored. That we did not pay an exorbitant price for this encumbering weight was only because we were meeting an enemy already short of shipping and other resources.

Why did Rome, rather than any of its many rivals in Iron Age Italy, become the core of an empire?

Why did Rome, rather than any of its many rivals in Iron Age Italy, become the core of an empire?

A muddy settlement on the Tiber turns into a machine that can raise armies, write laws that outlive empires, build roads that stitch a continent together, and carry water for millions through aqueducts, while running a Mediterranean-wide bureaucracy for centuries. The usual explanations are familiar: institutions, military discipline, geography, luck. All true, and none of them feels fully satisfying on its own. Many societies possessed some of these advantages. Rome was unusual in how consistently it turned them into scalable institutions.

There is another angle that is rarely discussed, mostly because until recently it was not testable. What if part of Rome’s advantage was carried in its people, as average differences in traits linked to learning, planning, and administration?

Ancient DNA makes it possible to ask that question directly. Using the AADR dataset and educational attainment polygenic scores, Iron Age and Republican-era Romans come out unusually high. Besides exceeding earlier Italian groups, they sit at the top of the entire ancient European distribution, even after accounting for sample age and genomic coverage.

That by itself does not explain the rise of Rome. But it does suggest a sharper hypothesis: Rome’s institutions may have been built and operated by a population that, on average, was unusually well suited to master and scale complex social systems.

Nothing is too good for the boys

Tuesday, March 10th, 2026

Soldier’s Load by S. L. A. Marshall ln our times, S.L.A. Marshall explains (in The Soldier’s Load and the Mobilty of a Nation), “we have permitted military thinking to become clouded by what social workers, psychiatrists, business counsel, public-relations advisers and morale experts have to say about what is proper in an army organized according to American standards, meaning the standards which are upheld in American institutions of a quite different nature”:

The military leader has become an unhappy worrier, confused and buffeted between rival groups of medicine men, each vending some special magic. He is told that a new order has arisen, that the rising generation is somehow different, that industrial change has revolutionized the military problem, that how he is presented to the public cuts more ice than what he really is and how he thinks, and that modern science and business methodology can rub a lamp and come up with the perfect answer to every age-old military problem.

[…]

From the viewpoint of the businessman, and of his particular friends in political life, the wartime Army is a great business institution, and a shining mark for the sale of any product which can be given even the pale shadow of a legitimate purpose. They press upon command to accept all manner of things which it would not normally consider. Public sentiment — “nothing is too good for the boys” — moves in the same direction. That these pressures are hard to resist is well understood by everyone who was familiar with the World War II atmosphere in Washington. That they are ever likely to become less is a wishful thought hardly sustained by the passage of postwar events.

In the realm of strategy, generals are just as much amateurs as heads of state

Monday, March 9th, 2026

No two heads of state could be more dissimilar in ambitions or temperament than Abraham Lincoln and Louis XIV, but when it came to the conduct of their wars, they shared much in common:

Both kept their generals on a tight leash, spending many hours a day in correspondence directing operations: Louis at his writing desk, Lincoln in the telegraph office. They paid especial attention to the theaters closest to their capitals — the Low Countries and northern Virginia, respectively (Louis established a courier service so efficient that a message sent in the morning could receive a reply that evening).

Neither man had experience commanding troops in the field, and both made serious mistakes as a result of their micro-management. Yet they also had good reason to take the approach they did. Fighting a war is very different from winning it, and their generals — though professionals in tactics and operational art — did not always see the larger picture. Domestic political constraints, economic factors, and foreign relations had just as much an effect on the course of the war as battlefield victories. In the realm of strategy, the generals were just as much amateurs as the heads of state.

In all of warfare, the leap from operational art to strategy is the hardest to make. Whereas operational art is in many ways an extension of tactics, dealing with the same sorts of considerations, strategy is different in both kind and scale. The problems it seeks to address are of a fundamentally different nature, as are the tools to effect it — yet by the very nature of the problem, it is almost impossible to train anyone to practice good strategy.

In its broadest sense, strategy is the art of accomplishing major national objectives. This encompasses far more than military force alone: it extends to industrial production, economics, diplomatic relations, domestic politics, and so forth. It is the logical extension of synergistic cooperation in warfare, from combined-arms tactics, to joint operations, to whole-of-government strategy. Good strategy is therefore a collaboration of a broad base of subject-matter experts.

Yet unlike other levels of warfare, nothing prepares practitioners from these separate fields to work together. An infantryman is not trained in the specifics of artillery employment, but is trained from the very beginning to fight as part of a combined-arms team. Junior officers frequently gain experience working alongside other services well before they are expected to plan or conduct joint operations. By contrast, there are far, far fewer opportunities for a military officer to work with industrial policy, economic warfare, or diplomacy before he reaches the three- or four-star level.

He foresaw that his army would be in continuous motion for at least three weeks

Sunday, March 8th, 2026

Soldier’s Load by S. L. A. MarshallOn the day before the Third Army was to attack into Brittany, S.L.A. Marshall explains (in The Soldier’s Load and the Mobilty of a Nation), General Patton was visited by Generals Lord, Stratton, and Eyster of Communications Zone:

They wanted to know how he was set as to supply and what he would expect of the rear establishment. He said, “Gentlemen, I’ve got three days of POL, ammunition and food. That’s all we need for the start. It’s up to you back there to get the rest of it up to me.” He then outlined the operation as he expected it to develop. Brittany was to be cut off. One flank was to turn toward Brest, and the other was to advance on and over the Loire River. In short, he foresaw that his army would be in continuous motion for at least three weeks. The records show that he made the shot just about as he called it. His critics sometimes say of Patton that he did not know logistics and that this was his handicap. That is at best a negative truth. What he didn’t know about the supply problem never slowed the movement of his armies. He respected the controlling principle. He would not overload his own forces. He demanded all the support that could be had from those who were in position to help them along. He may have missed a tree here and there but he kept his eyes on the forest.

The microbe keeps the core instructions for copying DNA and building the ribosomes that read it

Saturday, March 7th, 2026

A Japanese led team, working with international partners at Dalhousie University and University of Tsukuba, has described a microscopic archaeon called Candidatus Sukunaarchaeum mirabile that blurs the edge between living cells and viruses:

The story began when scientists sequenced DNA from marine plankton and noticed genetic fragments that did not match any known organism. Reconstructing those fragments revealed a circular genome of about 238,000 base pairs.

For comparison, the previous record holder among Archaea, Nanoarchaeum equitans, carries roughly 490,000 base pairs, so this newcomer has kept barely half the DNA of an already-minimalist relative.

Almost everything in this tiny genome is devoted to handling genetic information. The microbe keeps the core instructions for copying DNA and building the ribosomes that read it, yet the usual metabolic pathways for harvesting energy or making amino acids and vitamins are missing. It seems unable to produce most of what it needs and instead leans on its host for supplies.

The authors of the study describe it as a “cellular entity retaining only its replicative core”, a phrase that shows how close it comes to the line between a cell and something simpler.

Even so, Sukunaarchaeum is not a virus. It still builds its own ribosomes and messenger RNA instead of borrowing all of that machinery from its host. At the same time, its tiny genome and single-minded focus on making more copies of itself make its lifestyle look strikingly virus-like.

A report in Science notes that its DNA is “focused almost entirely on replication” and suggests it may sit on an evolutionary path between more conventional cells and fully-viral strategies.

The Russian will not be held back by terrain normally considered impassable

Soldier’s Load by S. L. A. MarshallWhile the supply discipline of the United States Army is regulated by the pressure to give troops all the comforts the middle-class American has learned to expect, S.L.A. Marshall explains (in The Soldier’s Load and the Mobilty of a Nation), the Russian Army, composed of men who have lived hard in their civilian environment, can operate in war on a minimum subsistence level without making its people feel abused:

As the Quartermaster General M. F. Kerner has pointed out, this means that the Communists have a relatively simple logistical problem,_ despite that we commonly think of the tran::portation of supply as being the weak link in the Soviet military system.

Many of Kerner’s revelations about how they improvise in the supply and technical field are highly significant. He continues:

“In my own experience I almost never saw a Russian military truck driver with the equipment to repair his tires. Hundreds of times I have watched these drivers patch up their punctures with the help of an empty oil can, a piece of crude rubber and the help of a heavy stone from the roadside. Piercing the upper part of the can, they filled the bottom with gasoline. Then they cleaned the tire tube, laid the crude rubber patch over the hole, and placed the stone on top. By setting fire to the gasoline, the patch was vulcanized to the tube in ten minutes.

“Fuel for the tanks was usually stored in huge cast-iron drums on trailers attached to the tanks and kept rolling along behind.

“When a tank was out of order, the troops improvised a repair shop in the forest by felling three trees, trimming their branches, and arranging them crosswise to make a lever for lifting the motor or any heavy part of the tank. Bridges were made entirely of timber. If the region was wooded, horses and oxen from local farms were commandeered to transport the trees; if there were no woods, the nearest wooden structure, whether a private home or a public building, was demolished and used for lumber.

“Russian engineers were trained in time of peace to construct wooden bridges, even massive bridges as high as 30 feet, such as those over the Don and Rivers. In the exigency of war, these engineers could put up a bridge with no other tools than axes, hammers and clamps.

“Every army has a system of priorities for supplying its fighting troops. But Soviet transportation, controlled entirely from a central office in Moscow, had a system of such sharp penalties inflicted for minor negligence that a small delay in loading and unloading operations was treated as a serious transgression. The personnel of all forms of transportation came under the jurisdiction of military tribunals which performed their duties right at the front, often trying and sentencing the offender within 24 hours of his dereliction.

“Staff training consists, as far as possible, in practice rather than in theory. During the war, military trainees had to study the current battles, analyze the mistakes made, and even visit the front to accustom themselves to actual combat. All branches of the army, including medical personnel and quartermaster corps underwent this same training.

“Little mail was transported to the front. A dilapidated three-to-four ton truck, no longer useful for priority materiel, sufficed to take care of the mail for a whole division. It was generally accepted as a mere weakness for the soldier at the front to want news of home, and the men were discouraged from writing. As in all other matters concerning the individual, the Russian soldier’s feelings were of no consequence.

“Their success with logistics, in sum, is due not to extraordinary skill and efficiency, hut rather to an endless ability to forage for themselves, to withstand the onslaught of the elements and to make do with whatever comes to hand.”

[…]

This is what [a German general] said: “The Russian will not be held back by terrain normally considered impassable. That was where we made some of our early mistakes. Gradually we learned that it was in just such places that his appearance, and probably his attack, was to be expected. The Russian infantryman could not only overcome terrain difficulties but was able to do so very quickly. Miles of corduroy road were laid through swamp within a few days. Beaten tracks appeared through forest covered in deep snow. Ten men abreast with arms joined, in ranks 100 deep, prepared these routes in 15-minute reliefs of 1,000 men each. Following this human snowplow, guns and other heavy weapons were dragged to wherever they were needed by other teams of infantrymen. During winter, snow caves which could be heated were built to provide overnight shelter for men and horses. Motorization was reduced to an absolute minimum, only the lightest vehicles being used. The horses were tough and required little care. The uniforms were suitable but the men were never over-clad. Mobility came of the mass of men which moved all loads, doing the work of machines when machines would no longer work.”

The entire economy becomes centered around making decisions that are financially safe rather than those that can lead to major payoffs

Thursday, March 5th, 2026

Labor laws are a large part of the explanation as to why the US is so much wealthier than Europe:

Americans do much better than Europeans, but the US is not clearly economically freer in most areas. For example, Heritage’s 2025 index of economic freedom puts it behind eleven European countries. The US is ranked 27th in the world in overall economic freedom, but 3rd in labor freedom. Given the degree to which the US has surpassed other major nations, perhaps indexes like this are underweighting the importance of this one particular category. America is far from a capitalist paradise; particularly in housing and allowing people to build, we do a pretty poor job.

[…]

Imagine if the entire force of government policy was put toward enforcing a status quo bias in other contexts: government created every possible financial incentive to keep people in the same homes; made sure they continually drive the same cars or buy vehicles from the same companies; or put up an endless number of barriers in the way of them switching grocery stores or banks. Everyone would realize that such policies represent the height of economic illiteracy and would be bound to have all kinds of unintended consequences. Yet we treat labor as different, even though the underlying economic principles are exactly the same.

[…]

In Germany, they not only tell you if you can fire people, but you can’t even decide who to keep! Paying employees indefinitely to leave is the optimistic scenario when they are no longer needed. The worse outcome is that you’re forced to hold on to them indefinitely.

Basically, what this system amounts to is a welfare state, while placing the burden on those who create jobs in the first place. To make another analogy, imagine we wanted to provide healthcare for the poor. But instead of paying for it through general taxation, we said anyone who provides any amount of charity to someone living in poverty must be the one to pick up the tab for their health insurance. How would such a system make sense? And this isn’t simply a matter of finding ways to provide welfare, but something much more extreme, involving locking employers in relationships they can’t get out of. You’re also misallocating labor, since having workers in places where they’re not needed prevents them from making a contribution elsewhere.

[…]

European workers don’t simply go to waste. Rather, the entire economy becomes centered around making decisions that are financially safe rather than those that can lead to major payoffs. The unemployment rate doesn’t look so bad, but you still get society-wide stagnation.

First came the captain in his scarlet uniform

Wednesday, March 4th, 2026

Soldier’s Load by S. L. A. MarshallOverloading has always been the curse of
armies, S.L.A. Marshall explains (in The Soldier’s Load and the Mobilty of a Nation):

Today we stagger along under a burden of soft drink machines, mammy singers and lollypops. In Wellington’s time, it was the soldiers’ wives and the regimental women which hindered movement.

While a prisoner in Srain, Baron Lejuene penned this arresting picture of military impedimenta in his time:

“First came the captain in his scarlet uniform, mounted on a very fine horse and carrying a big open parasol.

“Then came his wife in a pretty costume, with a very small straw hat, seated on a mule, holding up an umbrella and caressing a little black and tan King Charles spaniel on her knee, whilst she led by a blue ribbon a tame goat, which was to supfly her night and morning with cream for her cup o tea.

“Beside madam walked an Irish nurse, carrying slung across her shoulder a bassinet made of green silk, in which reposed an infant, the hope of the family.

“Behind madam’s mule stalked a huge grenadier, the faithful servant of the captain, with his musket over his shoulder, urging on with a stick the long-eared steed of his mistress.

“Behind him again came a donkey laden with the voluminous baggage of the family, surmounted by a tea-kettle and a cage full of canaries, whilst a jockey or groom in livery brought up the rear, mounted on a sturdy English horse, with its hide gleaming like polished steel. This groom held a huge posting whip in one hand, the cracking of the lash of which made the donkey mend its pace, and at the same time kept order among the four or five spaniels and greyhounds which served as scouts to the captain during the march of his small cavalcade.”

Most managers optimize for being informed

Tuesday, March 3rd, 2026

Anish Moonka summarizes the key points of Elon Musk’s interview with Dwarkesh Patel and notes that Elon’s methodology is always asking, what is the limiting factor right now, and how do I remove it?

Chip output is growing exponentially. Electricity production outside China is flat. By the end of this year, Elon predicts AI chips will be piling up faster than anyone can turn them on. The companies that win are the ones that can plug their chips in, not the ones that buy the most.

[…]

Solar panels produce 5x more power in orbit because there is no atmosphere, no day/night cycle, no weather, and no clouds. And you need zero batteries. Combined, that is roughly 10x the economics of ground-based solar. Space solar cells are also cheaper to manufacture because they require no glass or heavy framing.

[…]

Within five years, Elon predicts SpaceX will launch hundreds of gigawatts of AI compute into orbit annually, exceeding the cumulative total on Earth. That is 10,000 Starship launches a year. One launch per hour. 20 to 30 reusable ships rotating on 30-hour cycles.

[…]

Only three casting companies in the world make the specialized vanes and blades for gas turbines. They are backlogged through 2030. Everything else in a power plant can be sourced in 12 to 18 months. But without those blades, you have no turbine and no electricity.

[…]

Digital human emulation means an AI that can do everything a human worker can do at a computer: read screens, click buttons, type, think, and decide. NVIDIA’s output is “FTPing files to Taiwan.” Apple sends files to China. Microsoft, Meta, and Google produce nothing physical. If you can perfectly emulate a human at a computer, you can replicate the output of every one of these companies. Customer service alone is a trillion-dollar market with zero integration barriers.

[…]

Elon argues that programming AI to be politically correct, meaning to say things it does not believe, creates contradictory axioms that could make it “go insane.”

When humans represent less than 1% of total intelligence, it would be “foolish to assume there’s any way to maintain control.” The best case is AI with values that find humanity more interesting alive than converted to raw materials. Elon compares the ideal future to Iain Banks’ Culture novels, where superintelligent AI coexists with humans because it finds them interesting.

[…]

Elon runs weekly (sometimes twice-weekly) engineering reviews with skip-level meetings where individual engineers present without advance prep. He mentally plots progress points across weeks to determine if a team is converging on a solution. Time is allocated not to what is going well, but to whatever the current bottleneck is. If something is working great, he stays away.

Most managers optimize for being informed. Elon optimizes for being useful at the point of highest leverage.

They were warned that those who fell out would be killed on the spot

Monday, March 2nd, 2026

Soldier’s Load by S. L. A. MarshallAn army has to take absolute measures
against looting, S.L.A. Marshall explains (in The Soldier’s Load and the Mobilty of a Nation), or provide a moving conveyor belt which will carry junk to the rear:

Otherwise, what is likely to happen is best illustrated by the classic tale of Sergeant Bourgoyne, a member of Napoleon’s army at Moscow.

When the army quit Moscow on October 19, 1812, Bourgoyne hefted his pack and decided that it was too heavy. So he examined its contents to see what he could discard. According to his Memoirs, he found “some pounds of sugar, some rice, some biscuits, a partly full bottle of liquor, a woman’s Chinese dress embroidered in gold and silver, a bit of the cross of Ivan the Great, my own uniform, a woman’s large riding cloak hazel-colored and lined with green velvet, two silver pictures in relief, one representing the judgment of Paris on Mount Ida and the other showing Neptune on a chariot, several lockets, and a Russian prince’s spittoon set with brilliants.”

But having found the pack too heavy, Bourgoyne could not get out of his mind the visions of the lovely women in Paris who might be seduced by some of these objects. So he did not lighten the pack. He went on his way for another month carrying his treasures. Then at the Battle of Krasnoe he lost everything, including his sixteen rounds of ammunition which he had been unable to fire because the weight of the prince’s jewelled spittoon, and the other loot, had made him less than half a man.

[…]

Under conditions of far greater stress, Maj. Robert K. Whiteley, Medical Corps, noted this trait in human nature as he witnessed the organization of the “Death March” from Mariveles to Camp O’Donnell in the Philippines on April 10, 1942.

There was virtually no leadership in the camp and each man had to think things out for himself. Most of the men were extremely weak from malaria and dysentery. They were told at the start that the march would be about 120 miles, and they were warned that those who fell out would be killed on the spot.

Said Whiteley: “I was surprised at the inability of average men to weigh the relative importance of things and discard every object which meant increased danger. Many started out carrying extra blankets, shirts, drawers and extra shoes. Some carried sewing kits, mirrors, framed pictures, clocks, flashlights and cameras. These weights put many of them in the ditch. They paid. for the mistake with their lives.” They were not the first soldiers to do this; nor, I fear, will they be the last.

US confirms first combat use of LUCAS one-way attack drone in Iran strikes

Sunday, March 1st, 2026

U.S. Central Command has confirmed that the airstrikes on Iran involved the first combat use of the Low-cost Unmanned Combat Attack System, or LUCAS drone:

The LUCAS platform is a one-way attack drone reverse-engineered after the Iranian Shahed-136.

Built by the Arizona-based SpektreWorks, the drone, which can be launched via catapults, rocket-assisted takeoff and mobile ground systems, is a spinoff of the company’s FLM 136 target model, one designed for counter-drone training while simulating Iran’s Shahed variant.

The FLM 136 model carries a range capability of around 500 miles, with a maximum payload of 40 pounds, or “roughly twice the explosive yield of a hellfire missile,” according to Alex Hollings, host of Sandboxx News’ FirePower.

With a maximum takeoff weight of 180 pounds, the FLM 136 is significantly lighter than the Iranian Shahed. The platforms are also immensely more cost-effective — and scalable — compared to the more advanced munitions in the U.S. arsenal, carrying a price tag of around $35,000 per unit.
