How old is the limit for enlisting in the Korean Army?
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.[1][2] Women are not required to perform military service, but may voluntarily enlist.[3]
Auxiliary police
There are currently five auxiliary police forces in Singapore:In South Korea, Auxiliary Police (AP) have a military-like structure, in that it consists of volunteers selected among eligible males (aged 18–35) who have not yet fulfilled the nation's obligatory military duty and the service in the Auxiliary Police is accepted as an equivalent of the military duty. The length of service for the auxiliary policemen is 21 months, which is identical to that of ROK Army enlistments. Also, within the Auxiliary Police rank, there exists four sub-ranks similar to the four enlisted ranks in the ROK Army: Private Constable (이경; "Yi-kyeong"), Private Constable First Class (일경; "Il-kyeong"), Corporal Constable (상경; "Sang-kyeong"), and Sergeant Constable (수경; "Soo-kyeong").
