context_page_description: This is the order of battle for United Nations and North Korean forces during the Battle of Pusan Perimeter in August and September 1950 during the Korean War. The engagement brought each side to muster substantial ground, air and sea resources to fight across southeastern Korea.
  The UN brought to bear hundreds of units from member countries South Korea, the United States, and the United Kingdom. Several other nations augmented the large naval task forces with ships of their own, including Australia, New Zealand, Canada, and The Netherlands. Opposing the UN force was the entirety of the North Korean military.
  UN forces proved superior to the North Koreans in organization and numbers, but UN forces also suffered from a lack of equipment and training, particularly in their ground forces. As the battles around Pusan Perimeter continued, UN forces and equipment continued to flood into Korea, giving them overwhelming advantages in their land, air, and sea components. Though many nations would eventually contribute forces to the Korean War, the majority of troops at the battle were American and South Korean only.
context_section_description: The United Nations forces were organized under the command of the United States Army. The Eighth United States Army served as the headquarters component for the UN forces, and was headquartered at Taegu. Under it were three weak US Divisions; the 24th Infantry Division was brought to the country early in July, while the 1st Cavalry Division and 25th Infantry Division arrived between July 14 and July 18. These forces occupied the western segment of the perimeter, along the Naktong river.
  The Republic of Korea Army, a force of 58,000, was organized into two corps and five divisions; from east to west, ROK I Corps controlled the 8th Infantry Division and Capital Divisions, while the ROK II Corps controlled the 1st Division and 6th Infantry Division. A reconstituted ROK 3rd Division was placed under direct ROK Army control.  Morale among the UN units was low due to the large number of defeats at that point in the war. US Forces had suffered over 6,000 casualties over the past month while the South Korean Army had lost an estimated 70,000.
  Troop numbers at the beginning of the battle were initially difficult to estimate for US and North Korean forces. Subsequent research indicates that the North Korean army had around 70,000 combat troops committed to the Pusan Perimeter on August 5, with most of its divisions far understrength. It likely had less than 3,000 personnel in mechanized units, and around 40 T-34 tanks at the front due to extensive losses so far in the war. MacArthur reported 141,808 UN troops in Korea on August 4, of which 47,000 were in US ground combat units and 45,000 were in South Korean combat units. Thus the UN ground force outnumbered the North Koreans 92,000 to 70,000.
  Throughout September 1950 as the battle raged, more UN forces arrived from the US and other locations. The 2nd Infantry Division, 5th Regimental Combat Team, and 1st Provisional Marine Brigade and a British Army brigade arrived in Pusan later in the fighting, along with large numbers of fresh troops and equipment, including over 500 tanks. By the end of the battle, Eighth Army's force had gone from three under-strength divisions to four fully manned formations which were well equipped and well prepared for war. By the end of the battle, the 27th British Commonwealth Brigade had arrived to assist the American and South Korean units.
