Conscription in South Korea
Conscription in South Korea has existed since 1957 and requires male citizens between the ages of 18 and 28 to perform in the army compulsory military service. Women are not required to perform military service, but may voluntarily enlist.
Military reserve force
With universal conscription, most of the male population may be reservists. In Finland, all men belong to the reserve until 60 years of age, and 80% of each age cohort are drafted and receive at least six months of military training. Ten percent of conscripts are trained as reserve officers. Reservists and reserve officers are occasionally called up for refresher exercises, but receive no monthly salary or position. South Korean males who finish their national service in the armed forces or in the national police are automatically placed on the reserve roster, and are obligated to attend a few days of annual military training for seven years.
