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.
Armed Forces Nursing Academy
“Professors and associate professors shall be appointed by the President with a recommendation by the Minister of National Defense, assistant professors shall be appointed by the Minister of National Defense with a recommendation by the Superintendent, and teaching assistants shall be appointed by the Superintendent.” 
All attendees of the academy will be registered into the military upon admission. One may not be younger than 17 years old or older than 21 years older and must be unmarried. One must also meet the physical standards of the Nursing Academy and have the educational background required. Those who successfully graduate and pass the national nursing examination will be commissioned as a second lieutenant in the Korean Military. Graduates will also obtain their Bachelors in Nursing. Those who fail will be removed from the military registry.
