Conscription in South Korea
By law, when a Korean man turns 18 years old, he is enlisted for "first citizen service," meaning he is liable for military duty, but is not yet required to serve. When he turns 19 years old (or, in some instances, 20 years old), he is required to undergo a physical exam to determine whether he is suitable for military service. The table below shows the physical exam's possible grades and their outcomes, according to the Military Service Act. Men must enlist by the time they turn 28 (Korean age).
The length of compulsory military service in South Korea varies based on military branch. Active duty soldiers serve 21 months in the Army or Marine Corps, 23 months in the Navy, and 24 months in the Air Force. After conscripts finish their military service, they are automatically placed on the reserve roster and are obligated to attend a few days of annual military training for 6 years.
Korean Liberation Army
The KLA brought together many Korean guerrilla armies that proliferated in northern Korea, Manchuria and mainland China during the 1920s. After the declaration of war by the Provisional Government against Japan and Germany on December 9, 1941, the units of the KLA participated on the allied side in the Chinese and Southeast Asian theatres. The "Regulation regarding the activities of the Korean Liberation Army", imposed by the Chinese Nationalist Government upon the provisional government in 1941, placed the KLA under the supreme authority of the Commander-in-chief of the Chinese army. This regulation was repealed in 1944, after the provisional government had achieved improved financial standing and greater importance in the eyes of the Chinese government.
