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.
Desegregation
At the end of June 1950, the Korean War broke out. The U.S. Army had accomplished little desegregation in peacetime and sent the segregated Eighth Army to defend South Korea. Most black soldiers served in segregated support units in the rear. The remainder served in segregated combat units, most notably the 24th Infantry Regiment. The first months of the Korean War were some of the most disastrous in U.S. military history. The North Korean People's Army nearly drove the American-led United Nations forces off the Korean peninsula. Faced with staggering losses in white units, commanders on the ground began accepting black replacements, thus integrating their units. The practice occurred all over the Korean battle lines and proved that integrated combat units could perform under fire. The Army high command took notice. On July 26, 1951, the U.S. Army formally announced its plans to desegregate, exactly three years after Truman issued Executive Order 9981.
