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 armour
Korean armor is armor that was traditionally used in ancient times by Koreans, those fighting in and on behalf of Korea, or Koreans fighting overseas. Examples of armor from the Korean Peninsula date back to at least the Korean Three Kingdoms period. Depending on the tactical situation, Korean armor also included horse-armor and other kinds of early anti-ballistic armor before the 20th century.
