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.

Article 55 of the Constitution of the People's Republic of China prescribes conscription by stating: "It is a sacred duty of every citizen of the People's Republic of China to defend his or her motherland and resist invasion. It is an honoured obligation of the citizens of the People's Republic of China to perform military service and to join the militia forces." The 1984 Military Service Law spells out the legal basis of conscription, describing military service as a duty for "all citizens without distinction of race... and religious creed". This law has not been amended since it came into effect. Technically, those 18–22 years of age enter selective compulsory military service, with a 24-month service obligation. In reality, numbers of registering personals are enough to support all military posts in China, creating so-called "volunteer conscription".>
