We must be strong there just as we are on earth

Friday, August 21st, 2020

In June 1965, the Directorate of R&D of the Future Weapons Office in Rock Island, Illinois published The Meanderings of a Weapon Oriented Mind When Applied in a Vacuum Such as the Moon:

The purpose of this brochure is to stimulate the thinking of weapon people all the way from those who are responsible for the establishment of requirements, through those who are responsible for funding, to the weapon designer himself.

“If space is truly for peace,” it reads, “we must be strong there just as we are on earth.”

It presents early thoughts and then corrected thinking, like this:

Although the widely advertised temperature of from –250° to +250° F. are actualities on the moon, they are the approximate extremes reached on the surface at midday and midnight. (Days and nights are two weeks long.) The surface of the moon is a poor conductor of heat, consequently a little shade during the day and earth light during the night, plus  a reversible white and black umbrella may be sufficient to keep the temperature in the vicinity of the space suit within limits of from –65° to +125 to +160° F. Assuming a direct proportion to the reflecting area, earth light on the moon will be sixteen times greater than moonlight on the earth.

The discussion involves some calculations. A “5 to 95 percentile” man has an unrestricted maximum line of sight of from 1.4 to 1.6 miles on the moon, with its mean radius of 1080 miles:

Any object propelled horizontally from the shoulder of a man six feet tall (shoulder approximately 5 feet above the surface) would impact the surface after an uninterrupted flight of 2.73 times its velocity. For a velocity of 3000 ft/sec the impact point would be 8190 feet or about 2500 meters. [...] Therefore, the maximum range of a projected object at a velocity of 3000 ft/sec is about 320 miles when propelled at an angle of 45 degrees with the lunar surface. Its maximum ordinate is approximately 80 miles above the surface.

Orbital velocity at the moon’s surface is 5,600 feet per second — totally doable.

Pages 10–16 could have come from an early 1980s sci-fi roleplaying game:

It is expensive to use aircraft in place of artillery

Thursday, August 20th, 2020

This Kind of War by T.R. FehrenbachThe Far Eastern Air Force quickly dominated the skies over Korea, T. R. Fehrenbach explains (in This Kind of War):

Unprepared for tactical ground-support missions, FEAF at first did almost as much harm as good, shooting up American positions and dealing grievous harm to friendly ROK units on the roads, but these mistakes were quickly corrected.

After gaining air control, FEAF began to interdict the ever-lengthening supply lines of the NKPA, throttling a great deal of its resupply to the front. But air over a country like Korea could never be in itself decisive. The country was too broken, and the NKPA was never completely road bound. Its units and its supplies, often on foot, went through the valleys and over the ridges, and too much of them arrived at the front. The NKPA did not amass the great, vulnerable mountains of matériel common to Western armies, because in the main it did not have them.

[...]

It is expensive to use aircraft in place of artillery — but in 1950 the United States had more aircraft, relatively, than cannon in the Far East.

[...]

All through the Korean War, whenever the enemy came out into the open, he was subject to immediate, effective air attack.

[...]

The NKPA became very good at camouflage and at night movement.

[...]

Based in Japan, which never changed from peacetime ways, many of them had wives and family stationed at their fields. Many a pilot flew out in the predawn darkness to strafe and rocket enemy troops all day across the burning hills of Korea, then returned to play cards with his wife at night.

This was harder on both pilots and family than if the dependents had been an ocean away.

This system, with Koreans, had some success

Tuesday, August 18th, 2020

This Kind of War by T.R. FehrenbachIn the first week of fighting, because it had exceedingly poor weaponry and bad training at staff levels, the original ROK Army in the west was largely destroyed, T. R. Fehrenbach explains (in This Kind of War):

Most of its men and officers died fighting.

[...]

ROK’s would remain weak in artillery and without organic tanks for the balance of the conflict. But they would fight.

All during July 1950, ROK units continued in action. Many fought exceedingly well. A comparison of casualties tells the story: in the first six weeks, American losses amounted to 6,000 men; the ROK’s lost 70,000 killed, wounded, or missing.

[...]

When the United Nations reeled behind the Pusan Perimeter, American officers estimated the NKPA had suffered some 30,000 casualties. The actual figure was nearer 60,000, most of which had been inflicted by the ROK’s. On August, many of the Inmun Gun divisions facing the Naktong were at half-strength; the total combat strength of its eleven divisions could not have been more than 70,000. It had no more than forty tanks by 4 August.

Behind the Perimeter on 4 August 1950, the U.N. had a troop strength of 141,808, of which some 82,000 were ROK’s. American combat ground strength was 47,000. By the end of August, when the crucial Perimeter battles began, American strength alone would exceed that of the Inmun Gun. By 19 August there would be 500 American tanks within the perimeter, outnumbering the enemy armor by more than five to one.

The United States Far Eastern Air Force had complete supremacy of the air, and could range over the North Korean supply lines at will. It could concentrate tremendous tactical air power against the ground in front of American troops.

For six weeks, the U.N. forces had been trading space for time. Their space was running out — but time was also running out for the Inmun Gun. In a protracted contest with the potential power of the United States, the North Korean State had no real hope of success.

By August the NKPA was bled white; replacements were fed in, some from the population of South Korea. These new men were hardly soldiers, but they were led by sergeants, officers, and generals who were fanatical veterans of the Chinese Communist Forces. Men who did not obey were shot. This system, with Koreans, had some success. It continued to be a matter of some frustration for American officers serving in Korea that Communist methods often turned out fighting men more quickly than the system employed with the ROK’s.

By 4 August 1950, the Inmun Gun had actually lost every advantage but two: it still held the initiative; though it was running out of men, supplies, and time, its attack spirit was still strong; and of its seventy thousand men, almost every man was available for the line. Given ammunition, the North Korean soldier could fight on three rice balls a day.

The far frontier is not defended with citizens

Sunday, August 16th, 2020

This Kind of War by T.R. FehrenbachIn addition to restraint of objective, T. R. Fehrenbach reminds us (in This Kind of War), the second necessary ingredient of limited war is a professional army large enough to handle any task:

In 1950, even to fight an underdeveloped nation in Asia, America had to fall back upon her citizens. And in this, above all else, lies the resulting trauma of the Korean War.

The far frontier is not defended with citizens, for citizens have better things to do than to die on some forsaken hill, in some forsaken country, for what seems to be the sake of that country.

[...]

A modern democracy was not semifeudal Prussia, or Bourbon France, or Whig England, where soldiers could be swept from taverns, pressed from the ranks of the unskilled and unemployed, the disadvantaged put under the rod of iron, to be broken into grenadiers, to voyage and die for the realm, while the stable and fortunate citizenry said good riddance.

Their cruel choice was that of cataclysm, humiliation, or surrender

Friday, August 14th, 2020

This Kind of War by T.R. FehrenbachIt was the boast of the great Frederick, T. R. Fehrenbach reminds us (in This Kind of War), that when he went to war neither the peasants of the fields nor the tradesmen of his towns should know or care:

Because Frederick involved his small state of Prussia in wars too big for even his iron grenadiers, he was not quite able to live up to his boast — but it is an accurate statement of the conditions of warfare in the Age of Reason.

In the eighteenth century, men and rulers were sick to death of unlimited war. For almost two centuries jihad had been preached; armies had crossed Europe like ravening locusts; millions had died; and at the end of the savagery nothing had been accomplished. The survivors still insisted on being Calvinists, Catholics, or Lutherans, short of extermination.

In Frederick’s time men were still men, and they must compete — but they no longer trusted the angel’s trumpet, or would have heeded had it blown. Wars there still were, but they developed in a new, a limited, fashion: to snatch a province here, to defend one there, to place a friendly head upon some throne, or to remove an unfriendly one from it.

The statesmen of Europe, even though they fought, wanted a certain order to the world. They called it the balance of power. It was a desperately fragile system, but it was the best they could design.

After two hundred years, and after a new resort to savagery in the period of the “nations in arms,” men had still evolved nothing with any more promise. There was a new hope of an eventual world order through the uniting of all nations in peace, but the hope was still only that, and no more. Power remained the fulcrum of world action. And unless some sort of balance could be maintained, the world would once again erupt in perhaps the last of all “holy” wars.

When the Soviet bloc pushed at the balance of world order in 1950, the men in the United States Government reacted the best way they knew how. So far as they would be able, they would reject resort to cataclysmic war. They felt, in their hearts, that a final test of strength between Communist and non-Communist would in the end decide nothing, except who remained alive in a shattered world. They would accept such a test only as a last resort.

They accepted, tacitly, to play the Communist game of limited war, for limited ends. It must never be forgotten that the game was pushed upon them — they did not precipitate it. Their cruel choice was that of cataclysm, humiliation, or surrender.

Communist armies tended to flow like the sea

Wednesday, August 12th, 2020

This Kind of War by T.R. FehrenbachA great and continuing weakness of the United States Army fighting in Asia, T. R. Fehrenbach argues (in This Kind of War), was its tactical and psychological dependence on continuous battle lines, such as had been known in Europe:

In Asia, terrain and Communist tactics made such lines rare — Communist armies tended to flow like the sea, washing around strong points, breaking through places where the dams were weak. The “human sea” analogy picked up and headlined by the press was very real — except that the press always gave a misleading indication of the numbers of enemy involved. Relatively small numbers of enemy flowed around the high ground held by American troops, went behind them, and interdicted their supply roads.

Road-bound, the American commanders became understandably nervous. Invariably, both men and leaders began to think of retreat, falling back to form a new line. This was in many respects a frame of mind. The North Korean forces in the American rear were small, ill supplied, and in effect often cut off from contact with their own bases.

Able to live on three rice balls a day, capable of carrying guns and ammunition over the steepest slopes on foot, this isolation bothered the Communists not at all.

It drove the Americans, hating isolated action, dependent upon wheels, to desperation. Ironically, the Indian-fighting army of seventy-five years earlier would have understood the new form of warfare perfectly. On the plains and mountains of the American West, the United States Army had once learned everything there was to learn about hit-and-run tactics and guerrilla warfare. It had learned to ride hard and march hard, live light, and to operate in isolated columns, giving the enemy no rest.

But even hard lessons can be soon forgotten.

Short of shooting them there was no way to keep the Koreans from using the bridge

Monday, August 10th, 2020

This Kind of War by T.R. FehrenbachThe last unit to flee across the Naktong river had a problem, T. R. Fehrenbach explains (in This Kind of War):

As the rear guard came across the bridge to the east side, throngs of Koreans followed them, filling the bridge with jostling bodies. General Hobart Gay, who had ordered the bridge to be sent up only at his express command, instructed them to go back to the far side, and clear the bridge.

This they did, as dusk approached. Then, with the refugees pushed back onto the west shore, the rear guard turned and pelted across to the friendly bank — but the second they turned, the Koreans dashed madly for the bridge and soon filled it, even before the cavalrymen were across.

Three times, at Gay’s order, they repeated the maneuver, without success. Short of shooting them there was no way to keep the Koreans from using the bridge. Even telling them it would be blown did no good.

Now it was growing dark, and the Inmun Gun was closing. As the rear guard recrossed to the east side for the third time, with the mass of Koreans close behind them, Hobart Gay, his face pale, said, “Blow it.” He had no other choice.

Several hundred Koreans went into the river with the bridge.

While ground warfare had changed little, the American society and the American soldier had

Saturday, August 8th, 2020

This Kind of War by T.R. FehrenbachAt the start of the Korean War, the American troops were driven back, T. R. Fehrenbach explains (in This Kind of War), but they weren’t at all prepared to retreat:

Gay, who had been Patton’s chief of staff in Europe, admitted he did not know how to conduct a retreat — thus far in his military experience he had never been involved in one.

[...]

The land viewed from afar is beautiful, rolling terraces and rice paddies, each a subtly different shade of green. But each paddy is a humid, stinking oven, and the bare hills are like broiler plates.

When they left their trucks and moved up onto the hills and ridges, American soldiers, as one officer put it, “dropped like flies.” Their legs, unused to hard pulls, gave out. The heat and exertion gave them throbbing headaches. During these weeks exhaustion and heat knocked out more men than NKPA bullets.

Short of water, lacking water discipline, they drank from ditches and paddies, developed searing dysentery.

They sweated until their shirts and belts rotted, and their bellies turned shark-white. Salt tablets became such an item of priority that they had to be air-dropped on units, along with vital ammunition.

Korea is a land cut by multiple hills and valleys, lacking roads. It is no terrain for a mechanized army. The principal — and sometimes only — means of getting from one place to another through the hills is shank’s mare. But American troops, physically unhardened for foot marches, were road-bound. They defended on roads, attacked on roads, retreated on roads. If their vehicles couldn’t go, they did not go either.

FEAF soon made the roads unpopular with the Inmun Gun. On the roads, tactical air strafed them, rocketed them, burned them. The Inmun Gun left the roads and went over the ridges, and it seemed to bother them not at all. They went stolidly up the slopes with the patient, sideways, Korean peasant tread, and they carried their machine guns, mortars, and mountains of ammunition with them.

They set their guns up on the high ground behind the Americans, interdicting their supply roads. Americans had trouble attacking up the hills to knock them off. And when their roads were blocked, Americans could hardly drag themselves over the hills to safety, let alone their heavy equipment. Second to the Soviets, the American Army became the principal supplier to the Inmun Gun of guns and ammunition.

The great problem was that in 1950, an infantryman in Korea was called on to do almost the same things Caesar’s legions had done, and to suffer the same hardships. In twenty centuries, infantry warfare has changed but little in the burdens it puts on the men in the mud. But in 1950, while ground warfare had changed little, the American society and the American soldier had.

For the first time, many Americans could understand what had happened to Britain at Dunkirk

Thursday, August 6th, 2020

This Kind of War by T.R. FehrenbachT. R. Fehrenbach explains (in This Kind of War) the American retreat at the start of the Korean War:

But most of the heroic actions had been those of individuals, of single officers or men who fought bravely and well. Because without tight discipline their bravery could not be coordinated into a team effort, many of these men died in vain.

[...]

None of them were equipped, trained, or mentally prepared for combat. For the first time in recent history, American ground units had been committed during the initial days of a war; there had been no allies to hold the line while America prepared. For the first time, many Americans could understand what had happened to Britain at Dunkirk.

[...]

Once aroused, a democracy can match a totalitarian state in every facet of strength — it can be stronger, for totalitarianism has built-in bureaucratic weaknesses. A Hitler can command, and men march — but a Hitler can go mad — and there is no one to say him nay.

But the abiding weakness of free peoples is that their governments can not or will not make them prepare or sacrifice before they are aroused.

[...]

Soldiers fight from discipline and training, citizens from motivation and ideals. Lacking both, it is amazing that the American troops did even as well as they did.

[...]

In actuality, the NKPA held a slight superiority in men on 20 July. By 22 July, U.N. and North Korean forces were on a par, and by the end of July United Nations forces actually outnumbered the Inmun Gun, an advantage they never again lost.

[...]

But men are not ciphers, nor do the battles always go to the big battalions.

[...]

But few correspondents saw that officers, giving crucial commands, could never be sure if their orders would be obeyed. A colonel who sends men to hold a vital hill, and who sees them again and again “take a vote on it with their feet” by marching to the rear, is soon apt to be a straitjacket case.

This is what a kiloton looks like

Wednesday, August 5th, 2020

If you haven’t seen the massive explosion in Beirut, it is legitimately terrifying:

That’s thousands of tons of ammonium nitrate going off, with roughly the energy of kilotons of TNT.

There’s not much left.

It was much easier to get a message to the rear than it was to get one carried forward

Tuesday, August 4th, 2020

This Kind of War by T.R. FehrenbachMajor General Dean found himself trying to hold back the North Koreans at Taejon, but, as T. R. Fehrenbach explains (in This Kind of War), he had almost no communications:

If he wanted to know what was happening to the front-line troops, he had to be on the front lines. He had found, sadly, that it was much easier to get a message to the rear than it was to get one carried forward.

[...]

He had three basic reasons for remaining inside the beleaguered city; one, to keep up the crumbling morale of the 34th Infantry and the other defenders by the sight of their commander moving shoulder to shoulder with them; two, to set an example for the ROK officers and staffs fighting alongside the Americans, who by now had all virtually climbed on the Pusan Express; and three, Bill Dean wanted to see close up just what kind of fighting cat the North Korean was.

[...]

The North Korean assault on Taejon was like all other North Korean attacks — they crashed into the defenders head on pinning them down, forcing them back, while at the same time they flanked or infiltrated to the rear and blocked the defenders’ retreat. At any given moment, it was impossible for Dean or any other commander to know what the situation was to his rear; this was a kind of tactic that the Europe-trained American officers, who liked to keep tidy lines, could not grasp until too late.

As it developed, Dean kept what he wanted of the 34th in the city, and sent other elements of the division, including his own HQ, to the east. As he would say much later, what he did afterward could have been done by any competent sergeant — but in saying this, Dean was thinking of the old Army, not the forces of 1950.

[...]

He decided to go tank hunting. He did not know it, but Colonel Beauchamp, to whom he had just given command of the 34th, was doing the same. Like Colonel Martin, Beauchamp had found everyone deathly sick of the T-34’s, but now things were just a bit better, for a few of the new 3.5-inch bazookas, designed to stop any known armor, had been flown in from the States.

With Beauchamp guiding and directing a team, the 3.5’s knocked out one tank west of Taejon.

[...]

Meanwhile, hundreds of North Korean soldiers, disguised in the white robes of farmers, were infiltrating into the city. Once inside, they threw off the misleading civilian attire and opened fire on American troops. Soon snipers were everywhere.

Using HQ and service personnel, American officers were having very poor success in rooting them out. Most American boys no longer knew how to play cowboys and Indians, particularly with live ammunition.

By afternoon, Dean had located another bazooka man, this time with an ammo bearer.

Dodging sniper fire, shooting a few snipers on the way, his party hunted up another tank. But this target was covered by North Korean infantry, and rifle fire kept them from getting close. Dean and the bazooka men sneaked back through a Korean courtyard, and climbed up to the second story of a house facing the street.

Here, cautiously looking out the street window, Dean saw the muzzle of the tank’s 85mm gun pointed at him, not more than a dozen feet away.

The bazooka man aimed where Dean pointed, and fired. The blowback from the rocket shook the whole room. The shaped charge burned into the tank at the juncture of turret and body

From the tank came a shrill, horrible ululation.

“Hit ’em again!” Dean said.

After the third round, the screaming ended abruptly, and the T-34 began to smoke.

[...]

Because he took the wrong turn, Bill Dean would not rejoin the American Army until September, 1953. Thirty-five days later, after wandering lost in the hills, after making heroic attempts to reach his own lines, Bill Dean was betrayed to the Inmun Gun by Koreans. When they jumped him, he tried to make them kill him, but they put ropes around his wrists and dragged him to a police station. There they threw him in a cage, the sort reserved for the town drunk.

Only much later did the Inmun Gun realize that the old-looking, filthy, 130-pound emaciated soldier they had captured was an American general.

General Dean once said that he wouldn’t award himself a wooden star for what he did as a commander. His country saw more clearly.

It gave him the Medal of Honor.

They too were paid to die

Sunday, August 2nd, 2020

This Kind of War by T.R. FehrenbachAt the start of the Korean War, casualties among officers of high rank in the United States Army were greater in proportion to those of any fighting since the Civil War, T. R. Fehrenbach explains (in This Kind of War):

They had to be. There were few operable radios with the regiments in Korea, and almost no communication from command posts down to the front positions.

If commanders wanted to know what was happening, or make their orders known, they had to be on the ground.

And the troops themselves, who had never developed any respect for N.C.O.’s or junior officers, often would ignore their orders — particularly if the order involved something unpleasant or unpopular.

Understandably, the junior leaders soon became defeatist. A great many of them died, recklessly, but it was not enough.

It was not because the colonels and generals had lost their minds that so many of them began to stand with bazooka teams or to direct rifle fire. There was no other way. So it was that men like Bob Martin were blown apart doing a rifleman’s job, or battalion commanders like Smith of the 3rd, 34th Infantry, collapsed and had to be evacuated, and men like Major Dunn, marching ahead of a rifle company, were lost.

The high-priced help was expendable, true. They too were paid to die. But it was no way to run a war.

No American may sneer at them, or at what they did

Friday, July 31st, 2020

This Kind of War by T.R. FehrenbachT. R. Fehrenbach (in This Kind of War) describes the demoralized retreat of the American troops in Korean:

Men threw away their shoes, because it was difficult to walk in the mud. They had no canteens, and they had no food. They were tired and dispirited, and some were bitter. The sun burned out of the clouds, and now the full brazen heat of Korean midsummer baked them. Some men grew dizzy and sick.

[...]

No American may sneer at them, or at what they did. What happened to them might have happened to any American in the summer of 1950. For they represented exactly the kind of pampered, undisciplined, egalitarian army their society had long desired and had at last achieved. They had been raised to believe the world was without tigers, then sent to face those tigers with a stick. On their society must fall the blame.

Martin did the only thing he could do, which was to try to set a personal example

Wednesday, July 29th, 2020

This Kind of War by T.R. FehrenbachColonel Bob Martin, in command of the 34th Infantry, had inherited a debacle, T. R. Fehrenbach (in This Kind of War) explains:

With a disintegrating command, it was not enough to issue orders; orders had a way of being ignored on company and platoon level. Martin did the only thing he could do, which was to try to set a personal example.

In the early morning, Bob Martin was hunting through the streets of Ch’onan with a 2.36-inch bazooka. It was no job for a regimental C.O. — but somebody had to do it. Leading the attack, gathering a small group of men about him, Martin engaged the enemy tanks.

With his regimental S-3 sergeant, Jerry Christenson, he stood in a hut east of the main street of Ch’onan, facing a T-34. Martin, acting as gunner, aimed the rocket launcher, and fired. The small, obsolete rocket charge fizzled out against the tank’s steel hull.

At the same time, the tank fired. At a range of less than twenty-five feet, the 85mm shell blew Bob Martin into two pieces.

The concussion burst one of Christenson’s eyes from its socket, but in great pain he managed to pop it back in. He was taken captive by the North Koreans.

The rash and the brave die early in a war

Monday, July 27th, 2020

This Kind of War by T.R. FehrenbachThe heart of the ROK Army, with the loss of its best men north of the Han, had broken, T. R. Fehrenbach (in This Kind of War) explains:

It had little equipment remaining from the Seoul debacle, and the troops who had been in the south were poorly armed, with old Jap matèriel. The staff had fallen into controversy, with more than one high officer shouting “Communists!” at his colleagues.

[...]

It was the Communist tanks, the ever-present, ever-leading T-34’s, which could not be stopped and could not be destroyed, that wrecked every plan and every hope of the ROK commanders. Lee Bum Suk had sound notions for fighting tanks — but now he could no longer find any ROK soldiers with the heart to try them. The rash and the brave die early in a war.

Lee’s successor, Chung Il Kwon, dropped the whole problem in the Americans’ laps. They were here now; their advisers had talked endlessly about the insignificance and vulnerability of Soviet tanks — now let the men from Mikuk, the Beautiful Land, fight the Communist tanks.

[...]

Each [American] soldier carried either an M-1 rifle or a carbine, with less than 100 rounds of ammunition. The company had three light machine guns, with four boxes of ammunition for each gun. Each platoon had only one Browning Automatic rifle, with a total of 200 rounds per weapon.

The Weapons Platoon dug in only three 60mm mortars. It also had 75mm recoilless rifles, but these it could have left behind, for the powers that be had issued no ammunition for them.

Nor were there any hand grenades.

When the Americans encountered North Koreans with tanks, they didn’t perform much better than their South Korean allies:

“Commence firing! Commence firing!” Collins shouted. Two other men, who were veterans of World War II, took up the shout.

The Americans on the hill could see the advancing Koreans plainly now, but almost no one fired. Collins turned to the two riflemen in his own hole.

“Come on! You got an M-1 — get firing! Come on!” He jabbed one of them sharply.

But most of the men stood slack-jawed, staring at the advancing Koreans, as if unwilling to believe that these men were really trying to kill them. For many minutes, only the squad and platoon leaders did any shooting, and more than half of the men never got off a round.

[...]

More than a dozen tanks converged bumper to bumper on the road, a beautiful target, and on the hill SFC Collins cursed because he had no ammo for the 75’s.

He called for fire from the battalion’s 4.2 — mortars — but a tank cannon shell burst near the single mortar observer, not harming him, but shocking him into speechlessness. No one else knew how to direct the mortars, and in the confusion the tubes stood idle.

[...]

The men left their field packs behind, and most of them forgot their spare ammunition. A few even left rifles in the rush.

[...]

Sergeant Collins, disgusted that so many of his men hadn’t fired on the enemy, went among his survivors, asking them why they hadn’t fired. A dozen of them said their rifles wouldn’t work. Checking, Collins found the rifles were jammed with dirt, or incorrectly assembled after cleaning.

Many of the men did not know how to put a rifle together. It wasn’t Collins’ fault, since he had joined the company only one day before.

[...]

The wounded who had made it could walk, but the shell-shocked mortar observer wandered around aimlessly if not helped. Men took turns helping him along.

The rain stopped, and the day became steamy, humid, and miserable. The men sweated. They had thrown away their canteens, and now they were forced to drink like animals from the muddy ditches and stinking rice paddies, fertilized with human feces.

That Korean term for America, Mikuk, can also be written as Miguk, which some have suggested as the origin of the term gook:

The word was used by U.S. Marines in the early 20th century; the earliest written example is dated 1920.

Folk etymology suggests that during the Korean War, young Korean children would point at U.S. soldiers and shout in Korean Miguk (“America”). Soldiers heard the word as “me gook”, as if the children were defining themselves as “gooks”. The soldiers proceeded to use that term to refer to the Koreans. The word guk itself simply means “country”. This explanation ignores the fact that there are many examples of the word’s use that pre-date the Korean War.

I was shocked to read Rhodesians calling black Communist guerrillas gooks (in A Handful of Hard Men).
