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.
Republic of Korea Armed Forces
Military service is mentioned as one of the Four Constitutional Duties (along with taxes, education, and labor) for all citizens. The current effective Conscription Law, however, applies only to males although women can volunteer as officers or non-commissioned officers. Military service varies according to branch: 21 months for the Army and Marine Corps, 23 months for the Navy, 24 months for the Air Force and civil service. The other professional civil service is from 26 months to 36 months. Korea had a bonus point system () which gives a person who completed military service bonus points when applying for a job, but it was found unconstitutional by South Korean constitutional court in 1999.
