->''"In war there is no substitute for victory."''
-->-- '''UsefulNotes/DouglasMacArthur'''

Known in America mainly as the war (or "police action", as it was officially known) featured in ''Series/{{Mash}}'', the war in the Korean peninsula, 1950-present. The two Koreas still have not signed a peace treaty, however after a long unofficial armistice, these two states have not resumed fighting, either. Despite the state of war, their relations have been more or less amicable at times, especially after 1998. It's often called "6.25 War" (referring to the date the war started, June 25th) or just "6.25" in South Korea and the "Fatherland Liberation War" in North Korea.

Both Korean states had been harassing each other along the border, and both had aspirations of placing the whole peninsula under their own style of government. On 25 June (6.25) 1950, North Korea took the initiative, crossed the 38th parallel and launched an invasion of South Korea.

The war played out much like a football game in which both teams make it to the one yard line only to fumble. In June 1950, the American forces occupying South Korea were in the process of closing shop, and the remaining soldiers had grown complacent and were unprepared for a war. When the North Korean army crossed the 38th parallel, it met ineffective resistance and quickly pushed the American and South Korean forces to the southern part of the peninsula. Even reinforcements flown in from Japan did little to stop the North Korean advance, but the US and SK forces finally established a solid defensive line around Pusan.

In the meantime, the United States appealed to the United Nations for intervention. Normally this would've been a waste of time, as the Soviets would've used their veto power to stop any such resolution. Luckily for the US, the Soviet delegation boycotted the meeting because the new Communist Chinese government hadn't been allowed to take its place on the Security Council.

UsefulNotes/DouglasMacArthur led coalition forces in a daring invasion at Inchon, on the Western coast of the peninsula. The expedition forced the North Korean army northward, back across the 38th Parallel and all the way to the Yalu River on the Chinese border.

At this point, the Chinese, concerned as much by the American army on their doorstep as the fate of their fellow communists, initiated a massive ZergRush which once again sent the UN forces reeling. At this point [=MacArthur=] started to become an even worse GeneralRipper (a decade before [[DrStrangelove the movie version]]) and [[UsefulNotes/HarryTruman President Truman]] had no choice but to fire him[[note]]Like most historical events, it was far more complicated than that. Essentially, [=MacArthur=] wanted to drive all the way into China, completely eradicating North Korea and probably starting a war with China. Truman, intelligently, didn't. However, [=MacArthur=] was dead-set in his plan, and ultimately made it clear that he was going to ignore the orders issued by the President (who is, after all, Commander-in-Chief of the armed forces), and Truman had no choice but to ask for his resignation. However, [=MacArthur=] essentially walked into the meeting with the President ''knowing that would happen'', and baited Truman into doing so. They actually parted amicably, agreeing that both sides had done what they needed to do: Truman would get to run the war the sane way, and [=MacArthur=] would get out of the war with his integrity intact[[/note]].

The new coalition commander, General Ridgeway, managed to stabilize the situation and soon the UN forces were pushing the enemy northwards again. This time they decided to stop at the 38th Parallel and hold the line until a peace treaty could be signed.

And in a sane world, that's where the war would've ended, after only a single bloody year. But negotiations dragged on for two more years, and men continued to die by the hundreds with no territorial gains for either side (much like WorldWarOne a generation earlier). The Soviet Union snuck in some pilots. The UN forces knew they were there, but weren't keen on starting a war with the [[Main/{{RedsWithRockets}} Reds With Rockets]]. Finally, in 1953 both sides agreed to a cease-fire that set up a demilitarized zone between the two countries, and remains in effect today.[[note]]Technically, though, as there never was an actual peace treaty between the two sides, the two nations are still at war with one another. There's even been a few incidents along the DMZ, as well as attacks on vessels in waters both nations claim as theirs.[[/note]]

Although the US and her allies technically won the war -- their main goal, maintaining South Korean independence, was achieved -- the long bloody stalemate has ensured that the war is remembered as a draw. Another, much more paradoxical, but, ironically, ''official'' point of view was that the war didn't technically happen ''at all''. Y'see, both halves of Korea consider themselves the only legitimate government, with their jurisdiction covering the entire peninsula[[note]]North officially considered Seoul its capital till 1972, and South still appoints governors for the northern provinces[[/note]], and the other contender as rebels and bandits. Thus, in their books, the whole war only counted as a police operation to bring the rebel provinces back, and Southern representatives weren't even present at the signing of the armistice.

The war saw the real start of jet-based air combat (jets had been used in UsefulNotes/WorldWarII, but only in the very late stages of the war and in no case did jet fight jet). On the plus side, this war took advantage of major advances in medicine and helicopter transportation to create very effective care for the wounded. For instance, if you were a UN soldier wounded in combat and arrived at a MASH unit alive in that war, your chances of survival there jumped to 97%.

It's somewhat of a forgotten war in the United States despite seeing just over half as many American deaths as UsefulNotes/TheVietnamWar (36,516 vs. 58,209 respectively, and over a far shorter period of time), 1,109 British deaths and a total body count that must be heading towards 3 million. In North Korea, however, the war has been used ever since as an excuse to villainize the United States and its "puppet government" in South Korea. Most of the population is led from birth to believe that the US is just waiting for the right moment to come in and "finish the job". Technically, the war is still ongoing as both sides have only ever agreed to a ceasefire, not any peace treaty. "Restarting" the war is a fairly common plot[[note]] This is probably less likely to occur now than at any other time since the actual war. Know that big Chinese brother whose assistance to North Korea is all over this page? Word is that they've totally turned their back on North Korea and are at the point that they would welcome Korean unification...''under Seoul's auspices''. At any rate, [[EagleLand the other giant that was involved in the war?]] Is now their no. 1 economic partner, and they ''definitely'' won't risk that for the Kims. That said, North Korea's raison d'etre is to continue the war, and they may eventually feel the pressure to try again, so the scenario isn't impossible.[[/note]].

!!Tropes include:

* AcePilot: The first jet aces for the United States, the Soviet Union, China and probably North Korea were made in this war. Although South Korea's air force didn't receive jet fighters until after the war and none of their pilots had the chance to achieve "ace" status in the technical sense (five air-to-air victories), their fleet of propeller-driven combat aircraft played a very active role in providing air support for UN ground troops, alongside flyers from Britain, Australia, South Africa and Canada.
** Ivan Kozhedub, the highest-scoring Allied ace of WorldWarII, was a military advisor on the North side, and, despite being officially forbidden to fly combat missions, reportedly had another five victories there, making him one of the rarest double (or even double-double) ace: in two different wars and both on a prop and a jet fighter.
* TheAlliance: The United Nations forces were an alliance of 17 nations. Not as large as the Allies of World War II, but [[YanksWithTanks the most important player was there]].
* AmericaSavesTheDay: Justified by the vast majority of UN forces being comprised of American infantry, [[StuffBlowingUp artillery]], and [[GameBreaker air support]].
** South Korean films often take this approach regarding their own servicemen in action.
* AttackAttackAttack: Faced with well-entrenched, well-supplied, and constantly reinforced UN troops, the North Koreans continued to assault the well-fortified Pusan Perimeter. [[BadassDecay Their losses here sapped them of their strength]], and the badly mauled North Koreans were shattered by [=MacArthur=]'s subsequent counterattack.
* AwakeningTheSleepingGiant: Faced with the military intelligence equivalent of a giant glowing neon sign saying, “Here be Chinese,” [=MacArthur=] insisted on continuing the advance on the Yalu River.
* BlatantLies: Chinese casualty reports claimed that allied forces lost twice as many soldiers as the Chinese. They also claimed every single allied tracked vehicle destroyed as a "tank", regardless if it... was a tank. Also, South Korean units under American command are sometimes regarded as American or even British.
** North Korea told an immense whopper early in the war, one they still hold to to this day -- the DPRK's Korean People's Army Navy claimed the sinking, in 1950, of the cruiser USS ''Baltimore'' during a PT boat action off the coast of Korea. This would be quite a feat, as at the time of her "sinking", ''Baltimore'' was 6,000 miles away, in mothballs. She would be reactivated in 1953, but was sent to the Mediterranean. She was scrapped for recycling in Portland, Oregon, in 1972. There ''was'' an incident at that location at that time, but it instead ended [[CurbStompBattle with three Allied ships destroying an attacking squadron of PT boats, then proceeding to completely dismantle a North Korean supply convoy.]] Even so, the PT boat that "sank" ''Baltimore'' is still on display at North Korea's Korean War museum until 2013.
** North Korea significantly whitewashed their history of the war, discreetly (or sometimes, blatantly) discarding any mention of the massive Chinese and Russian aid that kept the DPRK from becoming a historical footnote.
** North Korea also claims that they were invaded first by the Americans, and the initial invasion of South Korea was a counterattack.
* BloodKnight: This trope also got mixed with a helping of NiceJobBreakingItHero, as part of the reason that the Korean People's Army was able to steamroll South Korea at the beginning of the war was that the US had refused to equip Syngman Rhee's South Korean army with equipment beyond basic rifles after Rhee indicated he was determined to take a stab at conquering North Korea -- the last headache the US needed at that time.
* BritsWithBattleships: After [[SouthKoreansWithMarines South Korea]] and [[YanksWithTanks the United States]], Britain was the third-largest contributor to the UN military forces in Korea.
* CanucksWithChinooks: The Canadian Army played a large role in the Korean War,[[note]]with a peak strength of over 8,000 troops in-theatre, Canada was the fourth-largest contributor to the UN military effort in Korea, after South Korea, the United States and Britain[[/note]] and the Royal Canadian Navy's [[CoolShip "Tribal" class destroyers]] were very active in the NavalBlockade of North Korea and providing gunfire support to troops on the ground. The Royal Canadian Air Force didn't commit any combat units, but their [[http://en.wikipedia.org/wiki/Canadair_North_Star North Star]] transports played a large role in the UN forces' airlift operations and two dozen Canadian fighter pilots fought in Korea as exchange officers with the U.S. Air Force and U.S. Navy.
* ChineseWithChopperSupport: Subverted in that the Chinese leadership had to label the hundreds of thousands of soldiers, tanks, and planes they sent to Korea as "The Chinese People's Volunteer Army" to mask Chinese help for North Korea. [[UsefulNotes/TheAmericanRevolution It didn't work]].
** The way this worked in practice led to this wry observation from some wags:
--> It is a very well dressed volunteer indeed who shows up wearing a [=MiG=] fighter.
* UsefulNotes/ColdWar
* ColdSniper: Literally. The Chinese had used sniper (technically marksman) warfare extensively, and on many occasions held their lines by using snipers. But those sniper units were not supported well and many lost limbs due to frostbite.
** The Chinese word for a surprise shot is 冷槍 (leng3 qiang1), literally "cold shot".
* CoolAndUnusualPunishment: The Chinese were known to treat the non-Korean UN POW's reasonably well, especially in comparison to the North Koreans. However they did require all enlisted POW's to attend daily lectures for several hours on the virtues of communism and the evils of capitalism.
** Then again, "Brainwashing" was a direct translation of a Chinese word.
** Chinese POWs in South Korean/Allied Camps are tattooed with anti-communism slogans, sometimes with BlindIdiotTranslations, to prevent them from escaping. Extremely riotous ones are reported to have blood taken out beyond safe volumes.
* CoolPlane: [[http://en.wikipedia.org/wiki/MiG_15 There]] [[http://en.wikipedia.org/wiki/F-86_Sabre were]] [[http://en.wikipedia.org/wiki/Hawker_Sea_Fury quite]] [[http://en.wikipedia.org/wiki/Gloster_Meteor a]] [[http://en.wikipedia.org/wiki/Twin_Mustang few]].
* CivilWar: Until the UN and China involved themselves.
* CrowningMomentOfAwesome: Being war, more than a few options here.
** For General [=MacArthur=], the Inchon landings, breaking the supply lines for the siege battering on the [[http://en.wikipedia.org/wiki/Pusan_Perimeter Pusan Perimeter]], threatening to shove UN forces completely off the Korean peninsula.
*** Making this better was that the landings were a case of CrazyEnoughToWork. The KPA hadn't even considered a landing at Inchon ''possible'' due to the tide and the mud flats that would almost certainly trap any ships launching landing craft. However, using Japanese tidal charts and knowing when high tide would peak, the ships would move in an hour before or two hours after high tide hit its peak, launch landing craft, and then pull out into more open seas. The result was an overwhelming victory.
**** Even better, Mao had specifically pointed to Inchon as a potential invasion point when discussing strategy with Kim. Kim had ignored him
** [[NoExceptYes "Retreat, hell! We're not retreating, we're just advancing in a different direction."]] - Major General Oliver P. Smith, CO 1st Marine Division, during the breakout from the Chosin Reservoir.
*** To explain; though his quote later became a stock quote for military doublespeak, he was being completely serious. When you are '''''completely''''' surrounded by enemies, any movement is an advance. In his case, a particularly dangerous advance.
** For the Chinese, after almost a century of humiliation at the hands of the West starting with the Opium War, and the unequal treaties, and after the disastrous Sino-Japanese War, and the Chinese Civil War, the fact the the Chinese were able take to the field against the Western Allies for the entire war is one for the entire country.
** Even the "bit players" get their own. [[http://en.wikipedia.org/wiki/Battle_of_Yultong_Bridge Battle of Yultong Bridge]]. 900 Filipino troops versus several thousand of Chinese soldiers. End result: 50 Filipino casualties (wounded and KIA/MIA), heavy Chinese casualties. The position held.
** [[http://en.wikipedia.org/wiki/Outpost_Harry Outpost Harry.]] 500 American and 100 Greek soldiers versus an entire Chinese division of 13,000 troops. The Chinese launched attack after attack for eight days straight, but were continually repulsed. By the end, 4,500 Chinese soldiers were dead. American and Greek losses totaled in at 114 killed.
** Ironically, both sides claimed the Battle of Chosin Reservoir as a victory and consider it among their finest hours. For the Chinese, it was the first major battle involving thousands of soldiers in which they were able to [[JediTruth defeat]] a Western power. From the Allied point of view, given that the Chinese outnumbered them two to three yet they were able to inflict a ''twenty to one'' kill ratio against them, and that they were surrounded but managed to successfully break out of the encirclement and withdraw in good order, it was quite a success given the circumstances. Most would more or less call it a pyrrhic Chinese victory.
** The [[http://en.wikipedia.org/wiki/Battle_of_the_Imjin_River Battle of the Imjin River]] was one for the British Gloucestershire Regiment, who held out for two days on Hill 235 against vastly more numerous Chinese troops. The hill was renamed Gloster Hill after the war.
*** To elaborate on this, the British ended up surrounded and out of ammo. [[{{Determinator}} So they threw their ration tins at the enemy.]] The true extent of the massive Chinese casualties around Hill 235 may never be known, but estimates are very high, generally thought to be at least ''fifteen times higher'', than British losses (remember that the British were almost out of ammo and food). A small rivalry still continues to this day between the British and the American armies, as the British had in fact radioed for assistance, telling the US commander that things were "a bit sticky". The American, however, did not speak StiffUpperLip, and failed to realize that "a bit sticky" was what an American might call "fucking catastrophic". The Glosters later became known as the "Glorious Glosters".
-->'''Andrew Marr''': At Gloster Hill the world's most political army faced its least political one...and got a good kicking in return.
** [[http://en.wikipedia.org/wiki/Battle_of_Kapyong The Battle of Kapyong]], where two battalions of mainly Canadian and Australian soldiers, backed by a New Zealand artillery regiment, repulsed a vastly superior Chinese division. At one point, the Canadians were so overwhelmed by the Chinese forces that they had to call down artillery fire on their own position to stop the attacking Chinese. And an Australian major managed to call a US general for backup, who incredulously believed that the unit was wiped out. The major simply replied that "I've got news for you, we are still here and we are staying here!" The end result was: 31 Australians killed, 10 Canadians killed and ''over 1000 Chinese killed.''
** [[http://en.wikipedia.org/wiki/Battle_of_the_Ch%27ongch%27on_River The Battle of Ch'ongch'on River]] which was probably the most important battle of the war. The Chinese army, outnumbered by the UN forces which had 3 and half times the firepower, decisively defeats them using surprise attacks and infiltration tactics. Making it even more impressive, the typical PVA soldier only had 5 days worth of supplies and could only resupply by scavenging from the battlefield. The US army was expecting to be home by Christmas and instead was forced into the longest retreat in US military history. This was the battle that ended hopes of a united Korea.
* TheDeterminator: The First Marine Division at the Chosin Reservoir, which was outnumbered by three to one and divided into several detachments, each of which were cut off from each other and surrounded by the Chinese. Not only did they cut their way out, but they took their wounded and heavy equipment with them.
** The Chinese 45th Division at [[https://en.wikipedia.org/wiki/Battle_of_triangle_hill the Battle of Triangle Hill]]. In the initial UN attack, when troops ran short on ammo, they [[https://en.wikipedia.org/wiki/File:Battle_of_Triangle_Hill_Grenade_Throwers.jpg threw rocks down the hill instead]]. In the counterattack, even when flares broke the cover of darkness so important to Chinese infiltration tactics, soldiers advanced through relentless artillery fire to reach UN positions, causing some American observers to believe they were hopped up on drugs. This grim determination virtually annihilated the 45th Division in the course of the battle.
* EliteArmy: Both the Chinese People’s Volunteers and North Korean army probably started out as this, having gained combat experience in [[UsefulNotes/NoMoreEmperors twenty-three years]] of war against [[TheOtherChineseArmy the Nationalist Chinese]] and [[KatanasOfTheRisingSun the Imperial Japanese]]. However, as time went on and in spite of a triumphant effort, they turned out to be [[BadassDecay outpaced by a different side.]]
** The Chinese People's Volunteers were infiltration-focused, and complacent UN troops were [[ShockingDefeatLegacy greatly demoralized by their first engagements]]. On the other hand, [[CripplingOverspecialization due to being strictly light infantry]], the Chinese suffered heavy casualties from UN firepower. Also, [[WeaksauceWeakness they didn't have many radios]] and suffered severe quality decline as the war went on.
** The North Koreans began the war with a battle-hardened army trained in maneuver warfare by action in the Chinese Civil War, equipped with Soviet materiel, and accompanied by Chinese advisors. They routed the South Korean army in days and badly mauled the American 24th Infantry before the UN secured the Pusan Perimeter. However, they mauled themselves doing so even against inadequately equipped and generally newly-raised units, and when the Western Allies finally managed to bring fully-equipped forces into the fray the KPA all but suffered CriticalExistenceFailure and was effectively destroyed by 1951, leaving the war to be fought primarily by the Chinese.
** Of all of these, the combined UN Command started out the worst but came to dominate the war. Initially suffering from lack of equipment and inexperienced soldiers and always operating under a limited capacity to prevent the outbreak of WorldWarThree, the Western Allies were still very much the same force that had won WorldWarTwo and WorldWarOne. On top of this, they were also joined by the [[FightingForAHomeland South Koreans]] and [[EagleSquadron UN Contingents from across the globe]]. Within the first year of war the UN all but destroyed the North Korean military even while struggling with said inexperienced troops, poor equipment, and debilitating arguments between and within the [=GHQs=] and domestic governments. This was stopped by the Chinese taking advantage of their reckless over-extension to wrongfoot and smash them back, but the following year they reorganized again under [[FourStarBadass Ridgeway]] and from then on held all the cards in the war.
** The Battle Of The Chosin was about one thing, annihilating the [[SemperFi First Marine Division]]. The 1st Marines fought their way out of the Chosin and five of the ten Chinese divisions— the 124th, 79th, 58th, 59th and 60th were destroyed and never saw combat again in the conflict. When General Song (PLA 9th Army Group commander) sent his first battle plan to Mao, Mao responded:
--->'''Mao''' "The American Marine First Division has the highest combat effectiveness in the American armed forces. It seems not enough for our four divisions to surround and annihilate its two regiments. [You] should have one to two more divisions as a reserve force."
* ForeverWar: Technically, the war ''never ended,'' with North and South held back only by an Armistice and Sino-American intervention.
* TheFriendNobodyLikes: Syngman Rhee was, to put it mildly, a liability. On the communist side Kim Il-Sun was not much better.
* FriendOrFoe: During the Battle of Hill 282 in 1950, the Argyll and Sutherland Highlanders were under heavy attack by North Korean forces and called for air support. They then set up their white air recognition panels to prevent them from being bombed. Unfortunately, the North Koreans had set up their own white panels. Thus, when American Mustangs reached them, they couldn't properly identify who was who and ended up dropping their payloads right on top of the Argylls. [[NightmareFuel Said payloads were napalm bombs.]] [[NoKillLikeOverkill And then they strafed them.]] [[AwesomeMoments Despite this, the remaining Argylls managed to hold their positions long enough to evacuate all of their wounded.]]
* GameBreaker: The United States Air Force and Naval Aviation. The former carpet-bombed North Korea back to the stone age before establishing and enjoying complete air superiority over all of the Korean Peninsula for virtually the entire conflict. The latter bombed the crap out of anything red that moved. For both the North Koreans and the Chinese, the most dangerous profession wasn’t the front line infantryman, but [[BoringButPractical the truck driver]]. As a result, the North Koreans crumbled around Pusan from lack of supplies, and the Chinese suffered horrendous casualties from airstrikes, airstrikes, and [[ArsonMurderAndJaywalking frostbite]].
** The USAF once [[http://www.qmfound.com/riggers.htm para-dropped]] a ready-to-use bridge!
*** Guess you could say they [[{{Pun}} Dropped]] [[DroppedABridgeOnHim A Bridge On Them....]]
* GloryHound: One of [=MacArthur's=] worst traits as a commander. At his most extreme he verged on being TheStarScream.
* HeroicSacrifice: A well-known one among the Chinese, at least. It is October 19, 1952. Five days prior, UN forces initiated an attack that has gradually ground down the Chinese defenses on [[http://en.wikipedia.org/wiki/Battle_of_Shangganling Triangle Hill]], dominated by Height 598, and have captured the heights. Chinese units are ordered to counterattack after sundown, to minimize the effectiveness of UN artillery. Among the men participating in the attack is one Trooper Huang Jiguang, whose unit is pinned down by a crossfire of machine-gun positions situated on the height itself. With sunrise fast approaching and threatening to erase the gains made over the night, Huang Jiguang proceeds to go imitate [[http://en.wikipedia.org/wiki/Alexander_Matrosov Alexander Matrosov]], blocking a gun with his own body; in the slight lull of fire that follows, his fellows assault and capture the hill, however briefly-- UN forces would regain the hill over the next few days.
** Task Force Faith lost over 50% of its strength after being encircled by the PVA and fighting on and off for days, but helped set the stage for the successful Western Allied evacuation of the Chosin Reservoir.
* HeroicSecondWind: General Matthew [[HaveAGayOldTime “Old Irontits”]] Ridgeway, General Walker’s replacement (after Walker was killed in a traffic accident) soundly berated 8th Army staff until they sucked it up and stopped running from the Chinese. Due to Ridgeway’s abrasive and aggressive command, the 8th Army revived itself and pushed the Chinese back to the 38th Parallel. One should not have expected any less of the man who commanded [[ItsRainingMen the 82nd Airborne Division]] during WorldWarTwo.
* HollywoodTactics: Very much adhered to by the US 8th Army during their pursuit of the shattered North Koreans. The American GI, [[ThirdActStupidity believing the war to be over]], refused to step out of his truck to advance on foot, provide flank security, or even scout ahead for ambushes.
** Ditto the Chinese and North Koreans by the end of the war. Failing to adapt from strategies that worked against [[KatanasOfTheRisingSun the Japanese military]] and [[GeneralFailure Chiang's Nationalists]] when fighting the [[MoreDakka Western]] [[EliteArmy Allies]] meant that they stagnated after 1951.
* IdiotBall: The Chinese repeatedly warned that they weren't happy. Chinese troops could be heard discharging weaponry as the UN forces approached the Yalu. The Chinese said they didn't want people near the Yalu. Then the Chinese swarmed over the Yalu.
** Shortly after the Chinese attacked, General Edward Almond visited 1st Marine Division HQ, where he informed them that; 'The enemy who is delaying you for the moment is nothing more than remnants of Chinese divisions fleeing north.' He then proceeded to order the Marines to continue to attack north.
* MoralDissonance: [[http://en.wikipedia.org/wiki/No_Gun_Ri_Massacre The No Gun Ri Massacre]], amongst [[http://en.wikipedia.org/wiki/List_of_massacres_in_South_Korea other atrocities committed by both sides]].
* MoreDakka: The iconic [=PPSh-41=] was widely issued to the Chinese and North Koreans. Used in conjunction with Chinese infiltration tactics, they were ''very'' effective.
** The Chinese also deployed some surplus Shanxi-pattern Thompson submachineguns, and jury rigged captured Thompsons to fire 7.62x25mm rounds which performed better at long ranges.
** On a larger scale, this nicely sums up the American way of war, causing grievous casualties to the North Koreans and Chinese through [[StuffBlowingUp the profligate expenditure of copious amounts of high explosives]].
* MultinationalTeam: UN forces in Korea came from 17 different countries.
* NavalBlockade: [[http://en.wikipedia.org/wiki/Blockade_of_Wonsan The Blockade of Wonsan]], the successful denial of a strategic port to the North Korean navy.
* NiceJobFixingItVillain and/or NiceJobBreakingItHero depending on your Point of View: In the United Nations, the USSR (who supported the North Koreans) held a veto power in the Security Council (along with the US, UK, France and China) and could have prevented official UN participation in the war, but they were boycotting the body because at the time China's seat was held by the Republic of China (aka Taiwan) instead of The People's Republic of China.
** Apparently even if the USSR vetoed it, the US would take the issue to the general assembly which would have voted for the US at that time.
** Syngman Rhee had stated his intentions to invade North Korea. The United States, already dealing with the Cold War, ''really'' did not see the need to light the powder keg of Korea at a time when there was already a serious concern that the Soviets might launch WorldWarIII over Berlin. Their solution was to not equip the South Koreans with much more than rifles to prevent Rhee from crossing the 38th Parallel. Unfortunately, Kim il-Sung likewise was chomping at the bit to invade South Korea. [[FromBadToWorse And he had been equipped to the hilt by the USSR and China.]]
* NoOneCouldSurviveThat: The US General initially believed that the Canadian and Australian forces in the Battle of Kapyong were all wiped out. [[CrowningMomentOfAwesome He was wrong]].
* NonIndicativeName: The People's Volunteer Army, whose ground forces were almost completely made up of conscripts.
* NorthKoreansWithNodongs: The war was their first true baptism of fire as an official military force. Also very nearly their last.
* NotSoDifferent: South Korea was almost as authoritarian as North Korea during the war, minus the obsessive personality cult and Communist political system. When the war ended, South Korea gradually became more democratic (sort of anyway), while North Korea - to date - has not.
* NukeEm: Douglas [=MacArthur=] was sacked for advocating nuking China as well as acting insubordinate to President Truman.
** Historians tend to disagree as to the exact reasons behind Truman's dismissal of [=MacArthur=]. Certainly, the general's ''stated'' desire to drive all the way to the Yalu River was a consideration, as was his desire to use nuclear weapons in a world still reeling from the first uses. However, prior to US intervention, [=MacArthur=] ''had stated'' that if put in command he would push all the way to the Yalu, and that he would consider any and all weapons for possible use. When he flew home to meet Truman, they both knew he wouldn't be returning to his command of the UN forces. But, to throw another wrench in the works, [=MacArthur=] simply felt that he ''could not'' resign while the war was still ongoing and refused to be removed from command. Truman, for his part, felt that he ''could not'' ask for the resignation of a hero of World War II, but could not allow him to resume his command. In the end, he was forced to fire [=MacArthur=], which the general accepted without resistance.
*** Truman was not re-elected for President as a consequence of [=MacArthur's=] dismissal.[[note]]This is only technically true; Truman didn't really run, but he did let his name appear on a primary ballot, mostly because he hated the guy running for the Democratic nomination and hadn't yet been able to persuade anyone he did like to run as an alternative. Kefauver trounced Truman by a 3:2 popular vote margin in that primary, though.[[/note]] Apparently, that decision did not sit well with the American public[[note]]Or at least the New Hampshire public, for reasons already mentioned[[/note]].
* OhCrap: The first notion that anyone got of the Chinese taking an active role in the war was when the South Korean 1st and 6th Divisions, quickly followed by the US 8th Cavalry, vanished from the maps in the span of a day.
* PoliticallyIncorrectHero: Even by the standards of the time, [=MacArthur=] was especially bad in his opinion of the Chinese, Koreans, Japanese and anyone else who wasn't caucasian. Some of his most serious miscalculation were a direct result of his racial prejudices.
* ProperlyParanoid: Deconstructed. American forces had been ambushed numerous times by North Korean soldiers disguised as refugees, and so established a shoot on sight policy for refugees heading for American battle lines. This resulted in the No Gun Ri massacre.
* PyrrhicVictory: For China, the Battle of Chosin Reservoir. They suffered horrendous casualties against some of their best soldiers, were forced to disband two divisions, and had to keep their best army group out of most of the war.
** The entire war could be considered this for China. They did technically fulfill their goals (stop the US from occupying North Korea), but at the cost of 200,000 to 400,000 soldiers. Saving North Korea might not have turned out to be a very good move for them either.
* RecruitingTheCriminal: Initially, Chinese forces had few good snipers, but this changed when they managed to press old-school rural bandits into service. Banditry, which demanded individual initiative and wilderness survival skills in addition to marksmanship, translated well to sniper warfare.
* RedsWithRockets: They were there in the form of hundreds of trained jet pilots flying Chinese jets with Soviet serial numbers.
* SemperFi: The US Marines are rather proud of their showing at the landings at Inchon and the Battle of Chosin Reservoir.
* ShaggyDogStory: Three years of warfare resulted in a return to the same conditions as before (North and South Korea separated by the 38th parallel), with numerous dead, a renewed hatred of each other, and lots of pissed off allies for both of them. Ultimately, both sets of allies got what they wanted (return to status quo), both sides failed in their objectives (a unified Korea), and everyone was bloodier for it.
* SouthKoreansWithMarines: Their debut conflict, like those of the North. Due to being underarmed and organized primarily to oppress Syngman Rhee's political enemies, they did not acquit themselves well on land at first. However, they also [[ForWantOfANail stopped and destroyed the North's amphibious attempt to seize Pusan during the initial offensives.]]
* StiffUpperLip: A British force on the brink of being overrun failed to receive reinforcements from the Americans because the American commander failed to take account of this - the British commander described it as "A bit of a sticky situation".
* TheStrategist: [=MacArthur=], for his brilliant stroke at Inchon. Soon to be subverted (see GeneralFailure above).
* TankGoodness: Especially by the Allies; North Korean armor was fundamentally outmatched by heavier and better armed Allied vehicles, especially the M-26 Pershings using HVAP rounds; on more than one occasion, 90mm HVAP rounds managed to not only penetrate KPA [=T34/85s=]' frontal armor but keep going and punch straight out the back. It's howitzer equipped brother, the M45, also counts.
* TemptingFate: In the grand tradition of prideful armies, US troops were told that they would be home by Christmas just before their final push to drive the North Koreans into the Yalu River.
** Elements of X Corps, including its commander, General Almond ([=MacArthur=]’s chief of staff) actually got to the banks of the Yalu in the east. Their first action was to piss in it.
** From an operational standpoint, organizing X Corps completely separately from 8th Army, on the far side of a massive mountain range from any other friendly units.
** US troops in the 8th Army, a fresh crop of draftees whose sergeants were the only ones with World War II experience, tended to advance into abandoned North Korean territory [[HollywoodTactics by riding in the back of their trucks without flank security or reconnaissance patrols]].
* ThirdActStupidity: Allied Command developed this after the wildly successful Inchon landings and the equally successful breakout of the Pusan Perimeter. This led directly to The Bug Out when [[OhCrap the Chinese made their presence known]] by exploiting every mistake the Americans made.
** More literally by the Communists failing to adapt to a different kind of war after 1951, and the South Korean refusal to negotiate leading to the Battle of Kumsong, the only major Communist victory in the second half of the war and the only one where the Chinese had the advantage in firepower.
* WeHaveReserves: The Chinese found some success in this. The North Koreans before them also tried, but bled themselves dry of manpower through [[AttackAttackAttack constant assaults on the Pusan Perimeter]], existing only on paper after late 1950.
* WeWinBecauseYouDidnt: The only real loser of the war was North Korea, as they failed in their objective of annexing the South. The Chinese forces lost ''far'' more soldiers than the American-led UN forces, but they succeeded in their goal of keeping North Korea as a buffer zone, and in the end everything turned back the way it was before the war.
* WrittenByTheWinners: Zig-zagged. Since this war didn't have winners per se, every side rewrote it to make themselves look better. Obviously, the most extreme example of this is North Korea itself, probably the closest the conflict had to a loser, but China did so as well. According to them: The United States and their puppet states started the war instead of the Chinese ally of North Korea, the Chinese won the war rather than stalemating it after suffering incredibly disproportionate losses, and it was bravery and tactical brilliance that let the poorly-equipped Chinese forces win battles, not incredibly costly and pointless [[ZergRush Zerg Rushes]] and the fact that the UN was always fighting a limited war. Also, they were never in the war; just the Chinese People's Volunteer Army, a brave all-volunteer force separate from the normal Chinese military, and their air force totally wasn't mostly made up of Soviet "volunteer" pilots flying jets provided to them by the Soviet Union in the first place.
* YanksWithTanks: By far the most significant player in this drama, hindered only by their commitment of their best troops to defending along the Iron Curtain.
* YouAreInCommandNow: Happened twice to Matthew Ridgeway, first when 8th Army General Walton Walker died in a traffic accident, and second when President Truman sacked Commander of Forces in Korea General Douglas [=MacArthur=]
* ZergRush: Initially averted. Chinese tactics involved night-time infiltration, flanking, and extreme surprise and violence, as demonstrated at Onjong and Unsan. The sheer shock of these attacks against complacent UN troops led many to exaggerate Chinese numbers to justify their panicked flight during the "bug out." When the UN troops found their courage and fought back with superior firepower, the Chinese fared much, much worse - their lack of radios meant they couldn't change plans on the fly, and as battles wore on, Chinese tactics often devolved into waves of men attempting to "infiltrate" into the teeth of prepared UN forces because they couldn't be called back.

* ''Men of the Fighting Lady'', 1954 American film
* ''Men in War'', 1957 American film
* ''Sayonara'', 1957 American film
* ''Film/PorkChopHill'', 1959 American film
* The opening scene of ''Film/TheManchurianCandidate'' (1962) takes place in Korea, and most of the film deals with the aftereffects of one infantry unit's capture and subsequent brainwashing by Communists there.
* ''The Hook'', 1963 American film
* '''[[Film/{{MASH}} M*A*S*H]]''' (1970) Of course
* ''Welcome to Dongmakgol'', 2005 South Korean film
* ''[[Film/{{Taegukgi}} Taegukgi: The Brotherhood of War]]'' (AKA: ''Taegukgi hwinalrimyeo'', ''Brotherhood: Taegukgi''), a 2007 South Korean film. "Taegukgi" is a name for the flag of South Korea. The movie is about two brothers who get caught up in the war: the older brother does everything he can to get medals so he can request for his younger brother to be sent home; when he believes his brother has died in a fire he does a FaceHeelTurn to North Korea out of despair.
* ''Assembly'', 2007 Chinese film which also takes place during the Chinese Civil War
* ''Silmido'' is about the Second Korean War, a period of tension and armed skirmishes between 1966 and 1976.
* ''Inchon'', a 1981 American film funded by Sun Myung Moon. Famously considered one of the worst movies of all time, it "won" four [[UsefulNotes/GoldenRaspberryAward Razzies]]. As a box office failure, it's often mentioned in the same breath as ''Film/HeavensGate''. [=MacArthur=] was played by Creator/LaurenceOlivier, who [[TropeNamer provided the name for]] MoneyDearBoy when describing why he took the part.
* ''[=MacArthur=]'', a 1977 film, made in much the same vein as Patton, (shows us the titular General's story from the man's own perspective) shows the glorious career of General Douglas [=MacArthur=] during World War II up until the Korean War. The film showcases [=MacArthur=]'s brilliant successes in Korea and his unexpected failures, but the story maintains that [=MacArthur=]'s tactics are working and that he is quite capable of winning if President Truman will only allow him to utilize the full military might of the United States. The President refuses and [=MacArthur=] becomes disgusted at the politics game that Truman is playing, namely not wanting to go on an all-out war with Communist China and their ally Russia and to avoid possible nuclear war, and states very blatantly that there is no substitute for victory in a war and either you fight with everything you have or you don't fight at all. [=MacArthur=] is relieved of his command over the war and fades into obscurity until his eventual retirement from the Army and in his last moments as a General and as a soldier he addresses many young and aspiring soldiers/cadets at West Point about what his career in the Military has meant to him.
* Sheriff Will Teasle of the first ''Franchise/{{Rambo}}'' film is a Korean War veteran. It is implied on the movie (and explicit on the novel) that his IrrationalHatred for Rambo is because Korea (and his own sacrifices by proxy) has been all but swept under the rug by the American people while Rambo (a VietnamWar vet) is a walking symbol of the "new generation".

* James Salter's ''The Hunters'' is a novel set in the Korean air war which features an OfficerAndAGentleman and a particularly nasty GloryHound.
* ''The Bridges at Toko-Ri'', a James Michener novel subsequently made into a film
* ''Series/{{Mash}}'', a [[Literature/{{Mash}} novel]] (1968), [[Film/{{Mash}} film]] (1970), and TV series (1972-83)
* ''This Kind of War'', by T. R. Fehrenbach (1960). This is considered by many historians to be THE definitive history of the Korean War, and an excellent read on its own literary merits. It is also required reading for all US officer candidate cadets at West Point and all candidates for promotion to the rank of General or Admiral in the US military.
* In ManlyWadeWellman's ''Literature/SilverJohn'' stories, John is a Korean War veteran, though the reader only gets a [[NoodleIncident few hints]] about what exactly he did in the conflict.

* '''[[Series/{{MASH}} M*A*S*H]]''', which ran three times longer than the 'hot' part of the war.
* In ''Series/MadMen'', Dick Whitman is a soldier in Korea when his commanding officer--in a two-man camp!--is killed. As Whitman isn't doing too well for himself, he takes the dead man's identity- Don Draper.
* [[Series/FawltyTowers Basil Fawlty]] appearently served in the Catering Corps. He also claims to have a shrapnel wound on his leg when he needs an excuse.
* Jim Rockford on ''Series/TheRockfordFiles'' fought in Korea.
* In ''Series/{{Seinfeld}}'', George's father, Frank was a cook in the Korean War, and has traumatic flashbacks about the time he sickened his fellow troops by using bad meat.

* Jack Arnold, the father in ''Series/TheWonderYears'', was a veteran of the Korean War; a first lieutenant in the USMC to judge from his photographs.
* Phillip Drummond on ''Series/DiffrentStrokes'' is a Korean War veteran.

* The aptly named 2003 title ''Korea : Forgotten Conflict''. Its style of gameplay is very similar to that of the ''VideoGame/{{Commandos}}'' series.
* WarThunder includes aircraft that were used in the Korean War. An achievement for advancing up the Soviet tier tree is called "Spain to Korea".
* The ''VideoGame/SteelPanthers'' series has traditionally included a number of campaigns and scenarios focusing on the conflict. The third game in particular included a scenario based on the ill-fated [[HoldTheLine delaying action]] of [[http://en.wikipedia.org/wiki/Battle_of_Osan#Task_Force_Smith Task Force Smith]].
* The Cold War campaign in the ''Thrones and Patriots'' expansion of ''RiseOfNations'' allows the player (as the US or Soviet Union) to get involved in the war. The US has the option to decide whether to simply hold on to South Korea's original cities or push into the North - the latter action spurs China into action against you and pushes the worldwide DEFCON level down. The Soviets, in addition to taking on a more active role, can also decide whether to accept Chinese help in exchange for a non-agression pact lasting several campaign turns (that you can break early, also for a DEFCON level fall).
