How the US Army confronted its racial crisis in the Vietnam era

Monday, September 18th, 2023

Beth Bailey’s Army Afire: How the US Army Confronted Its Racial Crisis in the Vietnam Era opens with a litany of incidents that she presents as protests:

It is a stretch. Major Merritt, for example, was clearly a crank. The written statement he distributed to the press contained gratuitous sexual insults directed at the “seventy-five percent” of white officers who were raised by “mammy who was also his fathers [sic] mistress.” Subordinates told investigators that Merritt’s constant racial badgering included his claim that “once a white woman had a negro she would never go back to a white man.”

Bailey insists that the senseless death of Cpl. Bankston must be seen in the light of rising racial tensions at Camp Lejeune. She repeats, rather irresponsibly, a rumor than white Marines had beat a black man to death the year before and never been prosecuted. The source of this rumor is a LIFE magazine article from 1969 that says the author heard about it from black Marines, who gave no further details except that the man’s death was “attributed to natural causes” by authorities.

Searching Bailey’s book for verified incidents where white servicemen were the aggressors, one finds only a handful of cases. “In 1970, at Fort Carson, Colorado, a white soldier—working part-time as a filling station attendant—murdered the head of the local university’s Black studies program,” she writes. Bailey omits the relevant details: Roosevelt Hill Jr. was filling up his car with gas when Ellis L. Little of Kentucky called to check the validity of his credit card, which was a type Little did not recognize. A passenger in Hill’s car suggested Little might be calling the police, so Hill rushed into the station and attacked him, shouting obscenities. With Hill’s hands around his neck, Little drew a gun from a drawer and shot him in the chest. A grand jury declined to charge Little with any crime.

Germany was a hotbed of racial violence in the 1970s, with soldiers afraid to go out at night due to rampant attacks, but it is hard to determine exactly what were the grievances at issue. “White soldiers were being randomly attacked under cover of darkness,” Bailey writes. “Black soldiers had taken to carrying intimidating ‘soul sticks’ on base, cutting to the front of the mess hall line, blatantly ignoring regulations.” More than 1,000 crimes of violence by black soldiers against whites were reported in Germany in the first nine months of 1971. If this was a protest, what were they protesting?

Disparities in punishment was the complaint cited most frequently. Black soldiers were 14 percent of U.S. troops in Germany but received 80 percent of prosecutions for serious crimes, such as robbery, assault, and rape. One report found 2,984 crimes of violence by black soldiers during a period when white soldiers committed 740. Bailey does not consider the possibility that this reflected reality rather than prejudice.

The Finns have camouflaged the road with pines hanging in the air

Saturday, September 16th, 2023

When tiny Finland faced Stalin’s Soviet Union, it camouflaged everything with trees and foliage:

According to the caption that Hedenström attached to the photo, “The Finns have camouflaged the road to Raate, about 10 km from Russia, with pines hanging in the air, because right on the border there is an observation tower erected by the Russians.”

Finnish Road Camouflaged with Trees

The lines of trees wouldn’t obscure the road from a plane flying overhead, but it could block the view from a tower. From a low perspective, down the road, the lines gave the illusion of an uninterrupted sequence of trees. Upon scrutiny, it is possible to see wires connected to a series of poles on the right side of the road. The whole pines were hung from such poles or other trees with cables. Due to Hedenström’s angle, viewers can’t see the attachments of the first row of trees, so they seem to be floating in the air. (The weird shape on the top of the photo is just a defect in the negative.)

[...]

“The Finns didn’t have funds to buy artificial camouflage such as nets in vast quantities,” says Colonel Petteri Jouko, a military historian at Finnish National Defence University, “so they used trees, leaves, and foliage to confuse the enemy. They were accustomed to wilderness and took advantage of the forest, unlike the German soldiers operating in northern Finland.”

The decision to turn to the Mediterranean aroused dark suspicions among American planners

Thursday, September 14th, 2023

How Hitler Could Have Won World War II by Bevin AlexanderAmerican and British leaders knew they couldn’t defeat Germany without the Soviets, Bevin Alexander explains (in How Hitler Could Have Won World War II), but Stalin kept complaining that they were leaving the fighting to the Red Army and started putting out peace feelers in Stockholm:

Western leaders didn’t think these feelers would amount to much if they attacked the Germans directly and took pressure off the Soviet Union, as Stalin had been demanding for months. But the British and Americans were virtually immobilized by an acrimonious dispute about what they should do.

The Americans, led by George C. Marshall, army chief of staff, wanted a direct advance by a five-division amphibious landing around Cherbourg in Normandy in 1942 (Operation Sledgehammer).

But the British pressed for an indirect or peripheral strategy, a combination of massive air attacks on German cities and smaller, less-dangerous invasions in the Mediterranean.

[…]

Torch at once gained the advantage Roosevelt was hoping for: when Stalin heard about it, he stopped complaining about a second front. But the decision to turn to the Mediterranean aroused dark suspicions among American planners that Churchill was maneuvering the United States into the “soft underbelly” strategy. They feared this would lead to the invasion of Italy, and perhaps Greece, and fatally undermine the plan to collide with the Germans on the beaches of France.

President Roosevelt was less worried, because he hoped “an air war plus the Russians” could defeat Hitler, and a cross-Channel assault might not be necessary.

Storytelling needs to be practiced, just like flying or marksmanship

Monday, September 11th, 2023

Ian Strebel and Matt McKenzie are intelligence officers in the United States Army and Navy, respectively, who have found that creating a compelling narrative takes practice, which traditional military training does not provide:

This can be a big problem for military intelligence professionals — they are trained to deliver intelligence, not to tell stories, so the stories that commanders tell themselves win out. Despite studies showing people are far more likely to remember stories than statistics, the military trains new intelligence professionals to brief intelligence through rote memorization and presentation of information. Neither of us ever received formal training in how to present information and intelligence as a story. This breeds uncreative military intelligence professionals concerned more with being “right” or having all the facts than whether their information is absorbed. Often, when information is presented in this manner, without context, commanders don’t remember what is important or, more importantly, why something is important.

[…]

Militaries have used wargames to train ever since Lieutenant Georg Heinrich Rudolf Johann von Reisswitz introduced the concept to an initially skeptical Prussian General Staff in the early nineteenth century. Very simply, a traditional wargame is a board game that simulates some aspects of military combat. The popular game of Risk is a very simple wargame, while chess can be considered as one of the oldest. Wargames can be successful mediums for training, in part, because the narrative holds players responsible for their actions and emotionally attaches them to the game’s results. Tabletop role-playing games are just the modern evolution of the classic wargame.

[…]

Tabletop role-playing games are unique from traditional wargames because the collaborative nature of the game means that almost anything can happen. The rules of these games only help structure the narrative and determine the consequences of actions. Players are free, even encouraged, to try anything they can imagine within the limits of that narrative. Most tabletop role-playing games have several rulebooks, but, as with military doctrine, the rules do not and cannot account for every eventuality. Instead, games such as Dungeons & Dragons rely on players’ creativity and flexibility to develop and adapt rules as they go. One of the most essential aspects of such games is the application of chance, usually employed by rolling various-sided polyhedral dice, which encourages out-of-the-box thinking for players and Dungeon Masters, especially in the face of catastrophic failure or, just as critical, catastrophic success.

These rules, when applied to wargames, can make them better — we have firsthand experience with this. Ian acted as an observer during a 2023 joint wargame using the Marine Corps’ Operational Wargame System. During the wargame, an experienced aviator wrestled with the decision of whether to use an exquisite munition to attack a threat reconnaissance drone or let the drone continue unimpeded. Recalling recent footage showing a Russian fighter jet dumping fuel on a U.S. surveillance drone, which downed the MQ-9 into the Black Sea, the aviator said he’d do the same. The wargame moderator said it was a “nice try” but that the move was outside the rules. If, instead, they’d abided by tabletop role-playing game rules, the aviator and moderator would play out the situation. Most likely, the moderator or Dungeon Master would determine, on the fly, the probability of the move’s success based on the game-defined attributes of the two aircraft and ask the aviator to roll a die. The Dungeon Master would use the die results to determine success or failure.

An experienced Dungeon Master might further adjudicate the results by applying a range of outcomes based on the die roll. For example, on a twenty-sided die, a roll of a “1” (critical failure) might result in the loss of the friendly aircraft with no damage to the drone, while a roll of “20” (critical success) might down the drone with minimal fuel loss and allow recovery of the drone sensor equipment. Rolls in between could result in varying degrees and combinations of damage and fuel loss to both the friendly aircraft and drone, as deemed reasonable by the Dungeon Master. Simultaneously, the Dungeon Master would determine the enemy’s reaction to this unanticipated event, both tactically and strategically, as well as the opposing force’s long-term adaptation to this move.

This is not so different from a military intelligence professional’s job: think like the enemy, understand their capabilities, develop possible scenarios, and then play the adversary as operators run through their plans. As previously discussed, while service intelligence schools generally teach presenting just a few courses of action, in a real conflict, there are infinite threat scenarios. Modern intelligence professionals must be flexible, responsive, and creative, in both planning and ad hoc operations. The problem is, short of an actual conflict, there are practically no opportunities for these personnel to practice working in a wide-open world — this is where tabletop role-playing games could prove valuable. As Dungeon Masters, military intelligence professionals can build worlds and scenarios and act as the enemy, or red, force. Most importantly, they will learn to respond spontaneously to unexpected player actions — regardless of whether those actions are incredibly clever or incredibly stupid.

In the Netflix series The Diplomat, Keri Russell succinctly described the problem of intelligence storytelling in three short sentences: “Intelligence is a story. A story based on incomplete facts. Life or death decisions turn on whether people buy the story.”

[…]

Dr. James Fielder explained that when games are designed correctly, a synthetic environment is created that becomes real to the players. In such an environment, the learning becomes real even if the risk is not — at least not yet. This is the challenge for both Dungeon Masters and military intelligence professionals. Telling a compelling story that enables others to envision combat environments and the threats within them accurately can be the difference between success and failure.

[…]

Storytelling needs to be practiced, just like flying or marksmanship. Pilots can safely make mistakes in simulators or with instructors in the cockpit. Shooters can miss targets on a range until they understand the weapon firing process. Similarly, Dungeons & Dragons provides intelligence personnel the opportunity to practice storytelling with the ability to make and learn from mistakes. After all, if a dragon kills a party of adventurers because the Dungeon Master wasn’t clear, they can simply try again. There are no second chances when giving an operational intelligence briefing before a strike mission.

Wargaming has seen a resurgence in professional military education, something we wholeheartedly support; games make learning fun, effective, and memorable. But integrating games into this education isn’t enough. The armed services only send a military intelligence professional to formal training a few times over a long military career. Comparatively, tabletop role-playing games can provide regular practice for the skills needed in exercises, wargaming, and the real world. After all, as James Sterrett, chief of the Simulation Education Division at the U.S. Army Command and General Staff College, said, “Experience is a great teacher and well-designed games can deliver experiences that are tailored to drive home learning.”

They make a better argument for a “free” Kriegsspiel or a Braunstein Game than for D&D, but the basic argument is sound.

Stop robbing the little delivery robots

Sunday, September 10th, 2023

Since Los Angeles and Greenville, North Carolina are not Japan, their residents must be asked to stop robbing the little delivery robots that bring groceries and meals to customers:

Los Angeles TV station KTLA5 has recently reported on a number of robot theft and vandalism incidents in West Hollywood, where some robots have been robbed of the goods they’re delivering, including food. The robots are used by local restaurants and are built by Serve Robotics, which pointed out to KTLA5 that despite some incidents the robots still have a 99.9% delivery completion rate.

[…]

Early on delivery robot developers have tried to allay commercial customers’ concerns over the potential for theft from robots, showcasing locked compartments and plenty of surveillance tech on the robots themselves, in addition to loud sirens. After a honeymoon period of sorts early on in the pandemic where robots were generally left alone, this is no longer the case, and sirens aren’t stopping acts of theft and vandalism in all cases.

But Los Angeles isn’t the only place where robots are encountering safety issues. The campus of East Carolina University has also seen instances of vandalism against GrubHub robots, made by Starship, earlier this year.

[…]

As with far more widespread instances of front porch package thieves or shoplifters, despite the volume of video evidence the robots can produce the police have to actually take some investigative steps to identify and locate the suspects.

He didn’t want to give up his summer conquests, ephemeral as they were

Thursday, September 7th, 2023

How Hitler Could Have Won World War II by Bevin AlexanderAs the Stalingrad campaign came to an ignominious end, Bevin Alexander explains (in How Hitler Could Have Won World War II), Manstein presented to Hitler and the OKH a plan that would “convert a large-scale withdrawal into an envelopment operation” that would push the Russians against the Sea of Azov and destroy them:

Manstein’s idea would have thrown the enemy on the defensive and transformed the situation in the south. But Hitler refused. He didn’t want to give up his summer conquests, ephemeral as they were. He wanted to keep his troops not only at Stalingrad but in the Caucasus.

Manstein came to have wide personal experience with Hitler’s thinking about war and concluded that he “actually recoiled from risks in the military field.” Hitler refused to allow temporary surrender of territory. He could not see that, in the wide reaches of Russia, the enemy could always mass forces at one point and break through. Only in mobile operations could the superiority of German staffs and fighting troops be exploited. The brilliant holding action of the 48th Panzer Corps along the Chir River demonstrated how superior German leadership and flexible responses, if applied by the whole German army, almost certainly could have stopped Soviet advances and brought about a stalemate. But such a policy was beyond Hitler’s grasp.

Manstein also found that Hitler feared to denude secondary fronts to gain superiority at the point where a decision had to fall. For example, the failure to assemble a large army to relieve Stalingrad had proved disastrous. Hitler could not make rapid decisions. In most cases he finally released too few troops, and sent them too late.

“Obstinate defense of every foot of ground gradually became the be all and end all” of Hitler’s leadership, Manstein wrote. “Hitler thought the arcanum of success lay in clinging at all costs to what he already possessed.” He could never be brought to renounce this notion.

Write what I have spoken

Wednesday, September 6th, 2023

In 1905, famed Apache warrior Geronimo began dictating his story, through a native interpreter, to S. M. Barrett, then superintendent of schools in Lawton, Oklahoma. When, at the end of the first session, Barrett posed a question, the only answer he received was, “Write what I have spoken.”

In Chapter 20, Geronimo explains some of the unwritten laws of the Apache, starting with a description of their trial system

When an Indian has been wronged by a member of his tribe he may, if he does not wish to settle the difficulty personally, make complaint to the Chieftain. If he is unable to meet the offending parties in a personal encounter, and disdains to make complaint, anyone may in his stead inform the chief of this conduct, and then it becomes necessary to have an investigation or trial. Both the accused and the accuser are entitled to witnesses, and their witnesses are not interrupted in any way by questions, but simply say what they wish to say in regard to the matter. The witnesses are not placed under oath, because it is not believed that they will give false testimony in a matter relating to their own people.

The chief of the tribe presides during these trials, but if it is a serious offense he asks two or three leaders to sit with him. These simply determine whether or not the man is guilty. If he is not guilty the matter is ended, and the complaining party has forfeited his right to take personal vengeance, for if he wishes to take vengeance himself, he must object to the trial which would prevent it. If the accused is found guilty the injured party fixes the penalty, which is generally confirmed by the chief and his associates.

Preparation of a Warrior:

To be admitted as a warrior a youth must have gone with the warriors of his tribe four separate times on the warpath.

On the first trip he will be given only very inferior food. With this he must be contented without murmuring. On none of the four trips is he allowed to select his food as the warriors do, but must eat such food as he is permitted to have.

On each of these expeditions he acts as servant, cares for the horses, cooks the food, and does whatever duties he should do without being told. He knows what things are to be done, and without waiting to be told is to do them. He is not allowed to speak to any warrior except in answer to questions or when told to speak.

During these four wars he is expected to learn the sacred names of everything used in war, for after the tribe enters upon the warpath no common names are used in referring to anything appertaining to war in any way. War is a solemn religious matter.

If, after four expeditions, all the warriors are satisfied that the youth has been industrious, has not spoken out of order, has been discreet in all things, has shown courage in battle, has borne all hardships uncomplainingly, and has exhibited no color of cowardice, or weakness of any kind, he may by vote of the council be admitted as a warrior; but if any warrior objects to him upon any account he will be subjected to further tests, and if he meets these courageously, his name may again be proposed. When he has proven beyond question that he can bear hardships without complaint, and that he is a stranger to fear, he is admitted to the council of the warriors in the lowest rank. After this there is no formal test for promotions, but by common consent he assumes a station on the battlefield, and if that position is maintained with honor, he is allowed to keep it, and may be asked, or may volunteer, to take a higher station, but no warrior would presume to take a higher station unless he had assurance from the leaders of the tribe that his [Pg 190]conduct in the first position was worthy of commendation.

From this point upward the only election by the council in formal assembly is the election of the chief.

Old men are not allowed to lead in battle, but their advice is always respected. Old age means loss of physical power and is fatal to active leadership.

Scalp Dance:

After a war party has returned, a modification of the war dance is held. The warriors who have brought scalps from the battles exhibit them to the tribe, and when the dance begins these scalps, elevated on poles or spears, are carried around the camp fires while the dance is in progress. During this dance there is still some of the solemnity of the war dance. There are yells and war whoops, frequently accompanied by discharge of firearms, but there is always more levity than would be permitted at a war dance. After the scalp dance is over the scalps are thrown away. No Apache would keep them, for they are considered defiling.

The transparent battlefield has changed everything

Monday, September 4th, 2023

The War in Ukraine, Edward Luttwak notes, is a war that must be fought by sheer, grinding, attrition, just like the First World War on the Western Front, with almost none of the maneuver warfare exploits that made celebrities of Guderian, Rommel, Patton, and Rokossovsky in the Second World War, and Arik Sharon in 1967 and 1973:

All those masters of war won disproportionate victories with surprise offensives. Arriving in fast-moving columns, their forces greatly outnumbered and overwhelmed a specific sector, while the bulk of the enemy, distributed across an entire front, could not intervene in time.

In other words, “manoeuvre warfare” depends entirely on surprise. Even in the Second World War, there was reliable aerial photography, so that pre-battle concentrations of tanks, trucks and artillery tractors could not escape detection as they gathered over a period of weeks. But once the offensive columns moved, it was hard to keep them under observation, let alone predict their destination. Photography was impeded by night, clouds and enemy fighters, leaving more than enough uncertainty to deceive enemies with decoys, simulated radio traffic, and the false tales of double agents.

This is how it came to be that on D-Day, 6 June 1944, the strongest German Panzer columns ended up being massed behind Calais to face Patton’s fictional First United States Army Group, while the Allies were landing in Normandy 230 miles away. Douglas MacArthur’s Inchon landings in September 1950, which nullified a string of North Korean victories in the preceding months, likewise achieved total surprise by very elaborately simulating a landing at Kunsan, 100 miles to the south.

None of this could happen now. The Americans, Russians and other military powers have observation satellites equipped with synthetic-aperture radars, capable of revealing single tanks, let alone any large grouping of forces, regardless of visibility, while their returns are refreshed often enough to detect troop movements in hours if not in minutes. Any other information drawn from intercepts, aerial reconnaissance or ground observation merely supplements this reliable intelligence. It is enough to make the battlefield transparent and operational surprise impossible, killing off the manoeuvre warfare that can win battles quickly and without mounds of casualties.

In early summer, when the Ukrainians deployed the precious “operational reserve” they had built up, there was no great mystery as to what they would do with it: attack somewhere south of Zaporizhzhia and fight their way down to the Black Sea.

[…]

While the Ukrainians were training and deploying, the Russians south of the Dnipro were digging trench lines shielded by minefields that stretch roughly 625 miles — 185 miles longer than the Western Front at its greatest extent. Napoleon called this style of linear defence a “cordon”, a thick rope made of infantry to hold the enemy along a long front. And, in his own time, he rightly explained why cordons were the stupidest way of defending a front: the enemy would arrive in columns and easily cut through the few troops holding the particular sector they attacked.

But once again the transparent battlefield has changed everything. Watching the Ukrainians advance in real time, the Russians could send their forces to intercept them in equal if not greater numbers. And even if the numbers were equal, the combat would be unequal because the Russians would be shielded by their minefields and by their trenches.

People think that satellites are secure

Saturday, September 2nd, 2023

In a presentation at the Black Hat security conference in Las Vegas, Johannes Willbold, a PhD student at Germany’s Ruhr University Bochum, explained he had studied three types of satellites and found that many were utterly defenseless against remote takeover because they lack the most basic security systems:

“People think that satellites are secure,” he said. “Those are expensive assets and they should have encryption and authentication. I assume that criminals think the same and they are too hard to target and you need to be some kind of cryptography genius. Maybe it wasn’t a good idea to give this talk.”

Satellite operators have been lucky so far. The prevailing wisdom is that hacking this kit would be prohibitively expensive due to the high cost of ground stations that communicate with the orbital birds, and that such hardware benefited from security by obscurity — that getting hold of the details of the firmware would be too difficult. Neither is true, the research indicates.

For example, both AWS and Microsoft’s Azure now offer Ground Station as a Service (GSaaS) to communicate with LEO satellites, so communication is simply a matter of plonking down a credit card. As for getting details on firmware, the commercial space industry has flourished in recent years and many of the components used on multiple platforms are easy to buy and study. Willbold estimated a hacker could build their own ground station for around $10,000 in parts.

As an academic, Willbold took a more direct approach. He just asked satellite operators for the relevant details for his paper [PDF]. Some of them agreed (although he did have to sign an NDA in one case) and the results somewhat mirrored the early computing days, when security was sidelined because of the lack of computing power and memory.

He studied three different types of satellite: an ESTCube-1, a tiny CubeSat 2013 running an Arm Cortex-M3 processor, a larger CubeSat OPS-SAT operated by the European Space Agency as an orbital research platform, and the so-called Flying Laptop – a larger and more advanced satellite run by the Institute of Space Systems at the University of Stuttgart.

The results were depressing. Both the CubeSats failed at a most basic level, with no authentication protocols, and they were broadcasting signals without encryption. With some code Willbold would have been able to take over the satellites’ basic control functions and lock out the legitimate owner, which he demonstrated during the talk with a simulation.

The Flying Laptop was a different case, however. It had basic security systems in place and tried to isolate core functions from interference. However, with some skill, code, and standard techniques, this satellite too proved vulnerable.

The first Japanese feature-length animated film was made for the the Japanese Naval Ministry in 1944

Friday, September 1st, 2023

The first Japanese feature-length animated film — the first animé — doesn’t get much attention these days, even though it’s beautifully made, in a Disney-inspired style, because the film, Momotaro: Sacred Sailors, or Momotaro’s Divine Sea Warriors, was made for the the Japanese Naval Ministry in 1944 and released in 1945, a few months before Japan surrendered:

About 45 minutes in they start preparing for an airborne attack against a European colony.

The bumbling Brits who surrender to the Japanese are depicted…with a horn on their heads?

IMG_0039

The Japanese did have marine paratroopers in World War II, by the way:

The troops were officially part of the Special Naval Landing Forces (SNLF or Rikusentai).

[…]

Paratroop units were only organized on the very eve of the war, beginning in September 1941.

[…]

Two companies, numbering 849 paratroopers, from the 1st Yokosuka SNLF, carried out Japan’s first ever combat air drop, during the Battle of Menado, in the Netherlands East Indies, on January 11, 1942.

In street warfare the Germans forfeited all their advantages in mobile tactics

Wednesday, August 30th, 2023

How Hitler Could Have Won World War II by Bevin AlexanderThe Stalingrad campaign, Bevin Alexander explains (in How Hitler Could Have Won World War II), is one of the most poignant examples ever recorded of a ruler engineering his own destruction:

When the army chief of staff, Franz Halder, protested the self-defeating operations, Hitler removed him. Only in the late stages when the German 6th Army had been isolated and a quarter of a million men were about to be lost was Erich von Manstein able to induce Hitler to grant just enough leeway to keep the entire southern wing of the German army from being destroyed as well.

After Stalingrad, Germany surrendered the initiative in Russia. Hitler never could summon enough strength thereafter to alter the balance of power against him. Despite heroic efforts by his soldiers, he had doomed himself to the slow, inevitable destruction of his army and his regime.

Two elements of the 1942 campaign stand out. First, Hitler committed the oldest and most obvious mistake in warfare: he neglected the principle of concentration and split his efforts between capturing Stalingrad on the Volga River and seizing the oil fields of the Caucasus.

[…]

This brought on the second element of the campaign: Hitler, instead of being satisfied with an advance to the Volga and interdicting traffic on the river, which had been his stated aim, insisted on 6th Army capturing the city itself. This forced it to concentrate in the built-up area at the end of an extremely deep salient, offering the Russians an invitation to lock 6th Army in place by launching a street-by-street urban battle.

[…]

Yet Hitler refused to allow 6th Army to withdraw, and — because he had committed his other forces to the Caucasus — had insufficient troops to strengthen either flank of the salient.

[…]

At every stage Hitler made disastrous decisions — dividing his army in the first place, insisting on seizure of Stalingrad, refusing to allow 6th Army to retreat, failing to go all out to save the army once it had been surrounded, and refusing to heed evidence that the Russians were about to isolate the two army groups in the far south.

[…]

The German army in the east (Ostheer) came out of the winter of 1941–1942 with 2.4 million men on the front, counting replacements, more than 600,000 fewer than had started the campaign in June 1941. The situation was worst among infantrymen, whose numbers had fallen 50 percent in the south and 65 percent in the center and north. This weaker army had to defend a line that, since Hitler prohibited straightening out loops and protuberances, wove in and out for 2,800 miles from the Baltic to the Black Sea.

The quantity of German weapons was declining as well. Tank production was below 600 units a month. When Halder told Hitler Soviet tank manufacture was more than three times as great, Hitler slammed the table and said it was impossible. “He would not believe what he did not want to believe,” Halder wrote in his diary.

At least the Mark IV tanks had been rearmed with long-barreled high-velocity 75-millimeter guns and could meet the Soviet T-34s on better terms. But nearly a third of the artillery pieces were old French cannons, the number of combat-ready aircraft had fallen to half what it had been in June 1941, while shortages of fuel and ammunition were great and growing.

[…]

Hitler now made an irretrievable error. He had concluded, because of the initial success of the offensive, that Soviet strength had been broken, and diverted Hoth’s 4th Panzer Army south to help Kleist’s 1st Panzer Army cross the lower Don to open a path to the Caucasus.

“It could have taken Stalingrad without a fight at the end of July,” Kleist said after the war. “I did not need its aid, and it merely congested the roads I was using. When it turned north again, a fortnight later, the Russians had gathered sufficient forces at Stalingrad to check it.”

Panzer leader Friedrich-Wilhelm von Mellenthin voiced the opinion of nearly all senior officers in this campaign. When Stalingrad was not taken in the first rush, it should have been shielded with defensive troops and not attacked directly.

“By concentrating his offensive on a great city and resorting to siege warfare,” Mellenthin wrote, “Hitler was playing into the hands of the Russian command. In street warfare the Germans forfeited all their advantages in mobile tactics, while the inadequately trained but supremely dogged Russian infantry were able to exact a heavy toll.”

[…]

In his original plan, Hitler intended four armies to press into the Caucasus, while one went toward Stalingrad. Now three armies marched on Stalingrad — an objective of infinitely less importance than the oil fields — while two armies drove into the Caucasus.

This was lunacy to every professional soldier, and Halder protested to Hitler. But the Fuehrer paid no attention, and also ignored evidence of powerful Soviet formations to the east of the Volga and in the Caucasus.

[…]

General Gustav von Wietersheim, commanding 14th Motorized Corps, watched his strength decline. He recommended that 6th Army be withdrawn to the west bank of the Don, forty-five miles away. The only result was that Hitler removed him because he was “too pessimistic.”

As the German offensives stumbled to a halt, radical changes in leadership came about. On September 10 Hitler relieved List, because his army group had not captured the whole Caucasus. He did not name a successor, and commanded the army group himself in his spare time from supreme headquarters.

Hitler’s long conflict with Halder came to a head. Hitler reproached Halder and the army general staff, calling them cowards and lacking drive. When Halder presented proof of new Soviet formations totaling 1.5 million men north of Stalingrad and half a million in the southern Caucasus, Hitler advanced on him, foaming at the mouth, crying out that he forbade such “idiotic chatter” in his presence.

Halder, who looked and acted like a prim schoolmaster, persisted in explaining what would happen when the new Russian reserve armies attacked the overextended flanks that ran out from the Stalingrad salient. On September 24, Hitler dismissed him.

Hitler said arguments with Halder had cost him half his nervous energy. The army, he said, no longer required technical proficiency. What was needed was the “glow of National Socialist conviction.” He couldn’t expect that from officers of the old German army.

The new chief of staff was Lieutenant General Kurt Zeitzler, a tank expert and man of action. Zeitzler soon took note of the cliques and intrigue in Hitler’s headquarters, became excessively cautious, and did nothing to challenge Hitler’s decision to keep 6th Army at Stalingrad.

Yet, as Field Marshal Manstein wrote: “A far-sighted leader would have realized from the start that to mass the whole of the German assault forces in and around Stalingrad without adequate flank protection placed them in mortal danger of being enveloped as soon as the enemy broke through the adjacent fronts.”

A drone in the air has a more accurate picture of the direction and strength of the wind

Andrei Bogdanov, CEO of Barcelona-based drone company UAVHE, is not developing his Baduga flying rifle for the military:

The problem Bogdanov is trying to solve is the control of feral pigs. The Twitterverse mocked an American user who suggested that he needed an assault weapon to prevent his yard being invaded by “30-50 feral hogs” in 2019. But controlling these animals, which cause an estimated $1.5 bn in damage in the US alone each year, is a major challenge.

Hunters usually only kill a few in a pack, causing the rest to scatter. In Spain where Bogdanov is based, hunters shoot some 400,000 wild pigs every year, but this is not enough to stop the population rising.

[…]

Bogdanov, has developed Baduga, a hunting rifle mounted on a small drone. A smart suspension system keeps the weapon’s center of gravity below the point of attachment, and gyro-stabilization ensures that the barrel remains stable regardless of wind or motion. The sights, including a multispectral camera able to see in the dark, are mounted on the barrel.

Bogdanov says that the firing platform is effectively decoupled and independent from the drone, firing as easily as it would from a tripod. The system automatically compensates for recoil, and has a magazine of 60 rounds. A further development may see automated in-flight magazine changing.

Early versions of the design employed off-the-shelf gyros, the latest iteration is custom-built for this application and weighs around 4 kilos, with the rifle adding a similar weight. The platform is a standard heavy commercial drone, similar to those which carry movie cameras and survey instruments.

[…]

Bogdanov says his setup achieves an accuracy of better than 0.1 minutes of arc, so the limitation is the accuracy of the rifle and ammunition.

[…]

“Unlike ground shooters, a drone in the air has a more accurate picture of the direction and strength of the wind over the altitude spectrum — it is easily calculated from the drift of the aircraft relative to the ground,” says Bogdanov.

[…]

So why not go down the obvious route and develop this specifically as a weapon system for the defense sector?

“Despite a common myth, developments for the military do not bring in a lot of money,” says Bogdanov. “We have shown it many times, but so far the matter has not gone further than talks and interest from military customers connected with it.”

The tools of the academic-reactor designer are a piece of paper and a pencil with an eraser

Monday, August 28th, 2023

In 1953, then-Captain Hyman Rickover explained the difference between an academic reactor and a practical reactor:

An academic reactor or reactor plant almost always has the following basic characteristics:

  1. It is simple.
  2. It is small.
  3. It is cheap.
  4. It is light.
  5. It can be built very quickly.
  6. It is very flexible in purpose (“omnibus reactor”)
  7. Very little development is required. It will use mostly “off-the-shelf” components.
  8. The reactor is in the study phase. It is not being built now.

On the other hand, a practical reactor plant can be distinguished by the following characteristics:

  1. It is being built now.
  2. It is behind schedule.
  3. It is requiring an immense amount of development on apparently trivial items. Corrosion, in particular, is a problem.
  4. It is very expensive.
  5. It takes a long time to build because of the engineering development problems.
  6. It is large.
  7. It is heavy.
  8. It is complicated.

[…]

The tools of the academic-reactor designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone can see it.

The academic-reactor designer is a dilettante. He has not had to assume any real responsibility in connection with his projects. He is free to luxuriate in elegant ideas, the practical shortcomings of which can be relegated to the category of “mere technical details.” The practical-reactor designer must live with these same technical details. Although recalcitrant and awkward, they must be solved and cannot be put off until tomorrow. Their solutions require man power, time, and money.

Unfortunately for those who must make far-reaching decisions without the benefit of an intimate knowledge of reactor technology and unfortunately for the interested public, it is much easier to get the academic side of an issue than the practical side. For a large part those involved with the academic reactors have more inclination and time to present their ideas in reports and orally to those who will listen. Since they are innocently unaware of the real but hidden difficulties of their plans, they speak with great facility and confidence. Those involved with practical reactors, humbled by their experiences, speak less and worry more.

Deterrence is a game where a big enough mistake kills hundreds of millions if not billions of people

Saturday, August 26th, 2023

Putin’s War in Ukraine is a fairly clear example of the stability-instability paradox:

In a pre-nuclear world, an intervention like this would have risked a direct, conventional response from NATO; at least at the moment it seems clear that the political will for such an intervention exists and is only really restrained by escalation concerns. Consequently, while in a pre-nuclear world invading Ukraine would pose the real risk of sparking an unwinnable conventional war with NATO, in a nuclear world, the Russian Federation can remain relatively sure that the war in Ukraine will remain ‘cabined’ to Ukraine. Moreover, the fact that Russia has nuclear weapons and Ukraine does not means that in the event that Ukraine wins, their ability to exploit that victory would be extremely limited; they could not, for instance, push deeply into Russian territory without triggering a potentially nuclear Russian response. The invasion thus seemed ‘safe.’

More broadly, I think Beaufre’s thinking is actually quite applicable here. Putin’s invasion of Ukraine is a classic interior maneuver and the Russian plan of operations follows Beaufre’s thinking closely: rapid advances with airborne, armor and mechanized forces to try to produce a coup de main that would topple the government and present its replacement as a fait accompli before the rest of the world could react. Clearly that’s not the only thing motivating the Russian operational concept – there seems to have been quite a lot of self-delusion and wishful thinking about how welcoming the Ukrainians would be. That said, it seems fairly clear that the Russian operational plan was designed to try to produce that fait accompli in just a few days, but of course the problem with such lightning advances is that should something go wrong, it is likely to go very wrong, with units spread out and often deep into enemy territory with fewer forces holding rear areas. By contrast, for instance, the United States, far more confident in its exterior maneuvers creating the window of freedom of action to intervene, was able to adopt a fairly methodical approach to the 2003 invasion of Iraq.

Which goes to the next point: Russian exterior maneuvers prior to the invasion were also fairly obvious. The Russian Federation, while building up claimed it had no plans to invade and used ‘exercises’ as a pretense in an effort, one assumes, to maximize confusion in the event and thus make unified action by the rest of the world more difficult. At the same time, Russia attempted to orchestrate a number of false-flag attacks and other fake ‘provocations’ in order to justify their intervention. What is also fairly obvious is that those exterior maneuvers failed, in particular because they lacked any kind of credibility. The smokescreen only works if a meaningful proportion of people believe it. The strategy NATO intelligence agencies took, of ‘calling’ Russia’s shots in advance robbed the strategy of much of its power. Again, the exterior maneuver is all about perception: Russia needed to create a ‘grey-zone’ of acceptability for what it was doing and largely failed.

[…]

The logic of deterrence — in particular the fact that it is both very high stakes and also based entirely on perception — explains why NATO and especially the United States took any direct military action off of the table quite loudly well before the conflict began. Saying that ‘all options are on the table’ — as the United States routinely does with Taiwan — would have been a fairly obvious bluff. When Putin called that obvious bluff, it would have damaged the credibility and thus the deterrence value of that same statement when applied to NATO members or Taiwan, weakening the effect of US deterrence, and thus potentially encouraging another state (like China) to try to call an American bluff elsewhere (essentially inviting a piecemeal maneuver). And of course the danger to that is two-fold: on the one hand if the United States and NATO folds, it calls into question even more of its security arrangements, but if it doesn’t fold, the result is likely to be a major war which in turn could (and frankly probably would) lead to an escalatory spiral ending in the use of nuclear weapons.

Remember: deterrence is a game where a big enough mistake kills hundreds of millions if not billions of people.

[…]

At the same time basically everything that NATO is doing in Ukraine can be understood as having a dual purpose: both attempting to degrade Russian military capabilities (by sinking the Russian economy and arming Ukraine) but also as an exterior maneuver designed to alter the freedom of action of other players in the system. Unable to directly act against Russia due to the concerns of deterrence and escalation, NATO is seeking to close the window of freedom of action tight enough that wars of conquest sit outside of it. It is doing this by rallying world opinion to the imposition of massive economic costs, in an effort to signal that wars of conquest will have such tremendous negative repercussions (even if they don’t trigger direct intervention) as to never be worth the cost.

Nuclear deterrence need not be the end of war by nuclear powers

Friday, August 25th, 2023

In An Introduction to Strategy (1965), French general André Beaufre describes the indirect strategy:

In essence, this sort of strategy is the answer to how two nuclear powers can still compete with each other without triggering a nuclear war. It is, “the art of making the best use of the limited area of freedom of action left us by the deterrent effect of the existence of nuclear weapons.”

When I explain this to my students, I explain it in a spatial metaphor. Imagine two countries (let’s use the USA and the USSR for simplicity), both with nuclear weapons. They each have ‘red lines’ where they would use nuclear weapons. Neither country wants a nuclear exchange, so they have to avoid crossing their opponent’s red lines which would trigger that. But below that threshold, you have a window of ‘freedom of action’ — a sort of ‘space’ (really a set of options) — where either power can engage in all sorts of activity, including military activity (typically against third parties, as directly attacking a nuclear power is almost always over the red line). Beaufre’s term for the things you do inside the window of freedom of action to gain direct advantages is ‘interior maneuvers.’ For instance supplying weapons to the Afghan mujaheddin in order to degrade Soviet control of Afghanistan — that’s an interior maneuver. Intervening militarily to topple a government that is aligned with your competitor but who they have no formal obligation to protect — that’s also an interior maneuver.

But those two powers can also engage in activity designed to alter the window itself, to give themselves more freedom of action or their opponents less. Remember that deterrence is all about perception, not hard and fast rules. If you can convince the world (and your opponent) that a third-country regime isn’t worth defending (because it is evil or a pariah state, etc.), you can potentially do more or more extensive interior maneuvers against it without nearing that red line. Alternately — especially in a democracy — if you can convince your own people that a third-country regime is noble and just, you can generate the political will to harden your red line, thus closing down some of the freedom of action of your opponent. This sort of thing is what Beaufre terms the ‘exterior maneuver’ — efforts made not to manipulate the direct theater of competition, but the freedom of action each side has to act in that theater. A broad range of activities fit here, as Beaufre notes — appeals to international law, propaganda with moral and humanitarian bent, threatened indirect intervention, economic retaliation (sanctions), and of course ultimately the threat of direct intervention.

[…]

All of which means that nuclear deterrence need not be the end of war by nuclear powers; indirect strategy exposes a gap in Brodie’s dictum that the only useful purpose a nuclear military can have is to avert wars.

One such method that Beaufre discusses is what he calls the ‘piecemeal maneuver,’ but is often in English referred to as ‘salami tactics’ — including in this absolutely hilarious bit from Yes, Prime Minister, which is also a surprisingly good explanation of the method. The idea is that to make gains while avoiding escalation, a state can break up the gains they would make into a series of smaller actions, each with its own exterior maneuver ‘cover,’ so that it doesn’t rise to the level of triggering nuclear escalation. Putting together several such maneuvers could allow a state to make those gains which had they all been attempted at once, certainly would have triggered such an escalation. Beaufre’s example, unsurprisingly, was Hitler’s piecemeal gains before his last ‘bite’ into Poland triggered WWII.

Beaufre notes that for piecemeal maneuvers to be effective, they have to be presented as fait accompli — accomplished so quickly that anything but nuclear retaliation would arrive too late to do any good and of course nuclear retaliation would be pointless: who is going to destroy the world to save a country that was already lost? Thus Beaufre suggests that the piecemeal maneuver is best accomplished as a series of coups de main accomplished with fast-moving, armored, mechanized, and airborne forces seizing control of the target country or region before anyone really knows what is happening. The attacking power can then present the maneuver as fait accompli and thus the new status quo that everyone has to accommodate; if successful, they have not only made gains but also moved everyone’s red lines, creating more freedom of action for further piecemeal maneuvers.

Avoiding this problem is why NATO is structured the way it is: promising a maximum response for any violation, however slight, of the territory of any member. The idea is to render the entire bloc immune to piecemeal maneuvers by putting all of it behind the red line (or at least letting the USSR think it is all behind the red line). It is also why American forces are often forward deployed in effectively trivial numbers in key areas in the world in what are often referred to as ‘tripwire’ deployments. Those American forces, for instance, in Poland, the Baltics or on the Korean DMZ (and during the Cold War, in West Germany) were not there to win the war; their purpose was, in a brutal sense, to die in its opening moments and thus ensure that the United States was committed, whether it wanted to be or not. And the reason to do that is to signal to both enemies and allies that any incursion into allied territory, no matter how trivial, will cause American deaths and thus incur an American military response. In that way you can shift the red line all of the way forward, obliterating the area of freedom of action, but only for countries where such a commitment is credible (which is going to generally be a fairly small group).
