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.
Korea Medal
All persons awarded the Korea Medal also automatically received the United Nations Service Medal for Korea. The South Korean government offered to all UN militia the Korean War Service Medal, though regulations at the time did not permit persons from the Commonwealth to accept the decoration; in 2001, Queen Elizabeth II, as Queen of New Zealand, approved the issuance of the Korean War Services Medal to all New Zealanders who had previously received the Korea Medal.
