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.
Indians in Korea
The Indian army provided a medical unit to attend the sick and wounded in the Korean War. With the communist invasion of South Korea in 1950, the UN sent out a call to the free world for assistance. India decided not to get involved militarily but contributed a medical unit, the 60 Parachute Field Ambulance which served in Korea for a total of three and a half years (Nov 1950- May 1954), the longest single tenure by any military unit under the UN flag.
They were involved in providing medical cover alternately to the US Army/ROK forces and the Commonwealth Division under the UN Command as well as the local civilians, and earned a very well-deserved title, "The Maroon Angels". The unit also looked after the North Korean POWs. The highlight of the tenure undoubtedly was when the unit provided an ADS and a surgical team (7 officers and 5 Other ranks) during Operation Tomahawk, an airborne operation launched on 21 March 1951 by the US Army’s 187 Airborne Regimental Combat Team.
