Battle of Pusan Perimeter order of battle

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.

North Korean forces were inferior to the UN forces in number, but in several cases they were able to make up for this in superior training. North Korean air and naval forces were small and poorly trained and equipped, thus playing a negligible role in the battle. However North Korean ground troops were often well trained and well equipped with modern weapons. The protracted battle around the perimeter severely depleted these troops forcing the North Koreans to rely increasingly on conscripts and replacements, diminishing their advantage in the battle and leading them to an eventual defeat.

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.
