Article 5 Paragraph 1, Subparagraph 3 of the ROK Military service act classifies supplementary service as "Persons found to be capable of serving on active duty as a result of a draft physical examination, but not determined as those subject to enlistment in the military as active duty soldiers due to the supply and demand conditions of the armed forces".
After the abolition of the defense call-up and Bangwibyeong in 1995, and the call-up system for public service personnel was established, the Public-Service Advocate and the International cooperation service personnel were established.
Among them, supplementary military service by physical grade and educational background is based on the annual Conscription examination announcement by MMA.
It is called Military service exception or Special case of Military service (Korean: 병역특례; Hanja: 兵役特例; RR: Byeongyeok teukrye) in South Korea.
This is also consistent with the forced labor standards of the International Labour Organization's Forced Labour Convention in that it is a system that enforces non-military labor under the Compulsory Military Service Act.
