Question: Who had the fewest troops in the 1950s war in the country sometimes called "The Land of the Morning Calm?"

full_context: Document 1: Names of Korea: An early attempt to translate these characters into English gave rise to the expression ``The Land of the Morning Calm ''for Korea, which parallels the expression`` The Land of the Rising Sun'' for Japan. While the wording is fanciful, the essence of the translation is valid.
Document 2: Korean War: By August, the KPA had pushed back the ROK Army and the Eighth United States Army to the vicinity of Pusan in southeast Korea. In their southward advance, the KPA purged the Republic of Korea's intelligentsia by killing civil servants and intellectuals. On 20 August, General MacArthur warned North Korean leader Kim Il-sung that he was responsible for the KPA's atrocities. By September, the UN Command controlled the Pusan perimeter, enclosing about 10% of Korea, in a line partially defined by the Nakdong River.
Document 3: Korean War: By mid-1950, North Korean forces numbered between 150,000 and 200,000 troops, organized into 10 infantry divisions, one tank division, and one air force division, with 210 fighter planes and 280 tanks, who captured scheduled objectives and territory, among them Kaesong, Chuncheon, Uijeongbu, and Ongjin. Their forces included 274 T-34-85 tanks, 200 artillery pieces, 110 attack bombers, some 150 Yak fighter planes, 78 Yak trainers, and 35 reconnaissance aircraft. In addition to the invasion force, the North KPA had 114 fighters, 78 bombers, 105 T-34-85 tanks, and some 30,000 soldiers stationed in reserve in North Korea. Although each navy consisted of only several small warships, the North and South Korean navies fought in the war as sea-borne artillery for their in-country armies.
Document 4: Mapado: "Do" can either mean "province" or "island" in Korean. "Seom" means island in the Korean language as well, although "do" is a Sino-Korean word used in name compound words, but "seom" can stand alone. Filming for "Mapado" did not take place on an island, but in Dongbaek village in Yeonggwang County, South Korea.
Document 5: Korean War: In China, the war is officially called the "War to Resist U.S. Aggression and Aid Korea" (simplified Chinese: 抗美援朝战争; traditional Chinese: 抗美援朝戰爭; pinyin: Kàngměiyuáncháo zhànzhēng), although the term "Chaoxian (Korean) War" (simplified Chinese: 朝鲜战争; traditional Chinese: 朝鮮戰爭; pinyin: Cháoxiǎn zhànzhēng) is also used in unofficial contexts, along with the term "Korean Conflict" (simplified Chinese: 韩战; traditional Chinese: 韓戰; pinyin: Hán Zhàn) more commonly used in regions such as Hong Kong and Macau.
Document 6: Korea: In North Korea, China, Japan, Vietnam, and Chinese and Vietnamese - speaking areas, Korea as a whole is referred to as Chosŏn (조선, Joseon, (tɕoshʌn),, (朝鲜), Cháoxiǎn, (朝鮮), Chōsen, Triều Tiên (朝鮮) lit. ``(land of the) Morning Calm '').`` Great Joseon'' was the name of the kingdom ruled by the Joseon dynasty from 1393 until their declaration of the short - lived Great Korean Empire in 1897. King Taejo had named them for the earlier Kojoseon (고조선), who ruled northern Korea from its legendary prehistory until their conquest in 108 BC by China's Han Empire. This go is the Hanja 古 and simply means ``ancient ''or`` old''; it is a modern usage to distinguish the ancient Joseon from the later dynasty. Joseon itself is the modern Korean pronunciation of the Hanja 朝鮮 but it is unclear whether this was a transcription of a native Korean name (OC * T (r) awser, MC Trjewsjen) or a partial translation into Chinese of the Korean capital Asadal (아사달), whose meaning has been reconstructed as ``Morning Land ''or`` Mountain''.
Document 7: Comics: Many cultures have taken their words for comics from English, including Russian (Russian: Комикс, komiks) and German (comic). Similarly, the Chinese term manhua and the Korean manhwa derive from the Chinese characters with which the Japanese term manga is written.
Document 8: Korean War: Korea was considered to be part of the Empire of Japan as an industrialized colony along with Taiwan, and both were part of the Greater East Asia Co-Prosperity Sphere. In 1937, the colonial Governor-General, General Jirō Minami, commanded the attempted cultural assimilation of Korea's 23.5 million people by banning the use and study of Korean language, literature, and culture, to be replaced with that of mandatory use and study of their Japanese counterparts. Starting in 1939, the populace was required to use Japanese names under the Sōshi-kaimei policy. Conscription of Koreans for labor in war industries began in 1939, with as many as 2 million Koreans conscripted into either the Japanese Army or into the Japanese labor force.
Document 9: Korean War: Meanwhile, U.S. garrisons in Japan continually dispatched soldiers and matériel to reinforce defenders in the Pusan Perimeter. Tank battalions deployed to Korea directly from the U.S. mainland from the port of San Francisco to the port of Pusan, the largest Korean port. By late August, the Pusan Perimeter had some 500 medium tanks battle-ready. In early September 1950, ROK Army and UN Command forces outnumbered the KPA 180,000 to 100,000 soldiers. The UN forces, once prepared, counterattacked and broke out of the Pusan Perimeter.
Document 10: United States in the Korean War: The first battle the Americans entered in the Korean War was the Battle of Osan, where about four hundred strong landed in Pusan airport on the first of July. The American troops were sent off to Taejon the next morning where Major General John H. Church the head of U.S. field headquarters was confident in the US troop's strengths to push back the North Koreans. On July fifth the troops were finally put to the test when North Korean tanks crept towards Osan. The four hundred infantryman of the U.S. also called Task Force Smith opened fire on the North Koreans at 8: 16 am. Only four of the North Korean tanks were destroyed and twenty - nine kept moving forward breaking the US line. At the end of the battle only two more North Korean Tanks and two regiments of North Korean infantry were destroyed. The US had lost the battle, revealing that the mere sight of US troops would not reverse the military balance in Korea. By early August, the North Korean troops had pushed back the US and South Korean troops all the way to Naktong River, which is located about thirty miles from Pusan. The two weeks of fighting following this resulted in the most casualties of US troops than any other equivalent period of this war. However, during this time the US pushed supplies and personnel to Korea and by the end of July South Koreans and US troops outnumbered the North Koreans, although the North had pushed back the US and South by an amazing amount the North had suffered over fifty thousand casualties. Also because North Koreas supply lines were so lengthy and with the US in control of the water and air replenishing there losses were slow.
Document 11: Korean War: After the Incheon landing, the 1st Cavalry Division began its northward advance from the Pusan Perimeter. "Task Force Lynch" (after Lieutenant Colonel James H. Lynch), 3rd Battalion, 7th Cavalry Regiment, and two 70th Tank Battalion units (Charlie Company and the Intelligence–Reconnaissance Platoon) effected the "Pusan Perimeter Breakout" through 106.4 miles (171.2 km) of enemy territory to join the 7th Infantry Division at Osan. The X Corps rapidly defeated the KPA defenders around Seoul, thus threatening to trap the main KPA force in Southern Korea.
Document 12: Japan: Japan (Japanese: 日本; Nippon (ɲippoɴ) or Nihon (ɲihoɴ); formally 日本国 Nippon - koku or Nihon - koku, lit. ``State of Japan '') is a sovereign island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian mainland and stretches from the Sea of Okhotsk in the north to the East China Sea and China in the southwest. Coordinates: 35 ° N 136 ° E ﻿ / ﻿ 35 ° N 136 ° E ﻿ / 35; 136 The kanji that make up Japan's name mean`` sun origin'', and it is often called the ``Land of the Rising Sun ''. Japan is a stratovolcanic archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu, and Shikoku, which make up about ninety - seven percent of Japan's land area and often are referred to as home islands. The country is divided into 47 prefectures in eight regions, with Hokkaido being the northernmost prefecture and Okinawa being the southernmost one. The population of 127 million is the world's tenth largest. Japanese people make up 98.5% of Japan's total population. About 9.1 million people live in Tokyo, the capital of Japan.
Document 13: Korean War: Soon after the war began, General MacArthur had begun planning a landing at Incheon, but the Pentagon opposed him. When authorized, he activated a combined U.S. Army and Marine Corps, and ROK Army force. The X Corps, led by General Edward Almond, Commander, consisted of 40,000 men of the 1st Marine Division, the 7th Infantry Division and around 8,600 ROK Army soldiers. By 15 September, the amphibious assault force faced few KPA defenders at Incheon: military intelligence, psychological warfare, guerrilla reconnaissance, and protracted bombardment facilitated a relatively light battle. However, the bombardment destroyed most of the city of Incheon.
Document 14: Chinese characters: When learning how to write hanja, students are taught to memorize the native Korean pronunciation for the hanja's meaning and the Sino-Korean pronunciations (the pronunciation based on the Chinese pronunciation of the characters) for each hanja respectively so that students know what the syllable and meaning is for a particular hanja. For example, the name for the hanja 水 is 물 수 (mul-su) in which 물 (mul) is the native Korean pronunciation for "water", while 수 (su) is the Sino-Korean pronunciation of the character. The naming of hanja is similar to if "water" were named "water-aqua", "horse-equus", or "gold-aurum" based on a hybridization of both the English and the Latin names. Other examples include 사람 인 (saram-in) for 人 "person/people", 큰 대 (keun-dae) for 大 "big/large//great", 작을 소 (jakeul-so) for 小 "small/little", 아래 하 (arae-ha) for 下 "underneath/below/low", 아비 부 (abi-bu) for 父 "father", and 나라이름 한 (naraimreum-han) for 韓 "Han/Korea".
Document 15: Korean War: In the resulting Battle of Pusan Perimeter (August–September 1950), the U.S. Army withstood KPA attacks meant to capture the city at the Naktong Bulge, P'ohang-dong, and Taegu. The United States Air Force (USAF) interrupted KPA logistics with 40 daily ground support sorties that destroyed 32 bridges, halting most daytime road and rail traffic. KPA forces were forced to hide in tunnels by day and move only at night. To deny matériel to the KPA, the USAF destroyed logistics depots, petroleum refineries, and harbors, while the U.S. Navy air forces attacked transport hubs. Consequently, the over-extended KPA could not be supplied throughout the south. On 27 August, 67th Fighter Squadron aircraft mistakenly attacked facilities in Chinese territory and the Soviet Union called the UN Security Council's attention to China's complaint about the incident. The US proposed that a commission of India and Sweden determine what the US should pay in compensation but the Soviets vetoed the US proposal.
