Task Force Smith of the US 24th Division Bombing by the US Air Force

The military forces of the US were several times bigger than those of the other UN member nations combined, both in the number of troops and in combat power. The US Army sent 9 divisions including the 24th Division, the 25th Division, the1st Armored Division, the 2nd Division, the 3rd Division, the 7th Division, the 1st Marine Division, the 40th Division, and the 45th Division, 2 battle regiments, and numerous supporting units.

During the three years of the Korean War, the US deployed 300,000troops at its peak. In 1952 when the number of the UN forces reached the highest, 50% of the ground troops was the ROK forces, 40% was the US forces, and 10% was the forces of other UN member nations. It can also be said that most of military operations executed during the war were carried out by the US military forces. The role the US military forces played during the war was quite a decisive one, and the number of military operations the US military forces executed were too extensive to be counted one by one.

Later on, the US Navy came to play an important role in turning the war situations to our advantage with such diverse military activities as air strikes, bombardment with naval guns, transporting troops and other supplies from the US. Particularly in the Incheon Landing Operation and Hungnam Withdrawal Operation, the US Navy demonstrated their highly skilled battle capabilities.

As for the US Air Force, the 5th Air Force and the Strategic Bombing Command, under command of the Far East Air Force, operated air strikes to drain up the battle capabilities of the communist forces, and executed close air support operations to help the UN ground troops to carry out their duties more successfully. The US Air Force inflicted heavy losses on North Korean and Chinese forces throughout the war.
