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.
Swiss Armed Forces
Switzerland has mandatory military service for all able-bodied male citizens, who are conscripted when they reach the age of majority, though women may volunteer for any position. People determined unfit for service, where fitness is defined as "satisfying physically, intellectually and psychological requirements for military service or civil protection service and being capable of accomplishing these services without harming oneself or others", are exempted from service but pay a 3% additional annual income tax until the age of 30, unless they are affected by a disability. Almost 20% of all conscripts were found unfit for military or civilian service in 2008; the rate is generally higher in urban cantons such as Zurich and Geneva than in the rural ones. Swiss citizens living abroad are generally exempted from conscription in time of peace while dual citizenship by itself does not grant such exemption.
