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.
75th Ranger Regiment (United States)
The outbreak of hostilities in Korea in June 1950 again signaled the need for Rangers. Fifteen Ranger companies were formed during the Korean War. The Rangers went to battle throughout the winter of 1950 and the spring of 1951. They were nomadic warriors, attached first to one Regiment and then to another. They performed "out front" work—scouting, patrolling, raids, ambushes, spearheading assaults, and as counterattack forces to regain lost positions. In all six airborne Ranger companies, the 1st, 2nd, 3rd, 4th, 5th, and 8th, averaging 125 soldiers in each company served during the conflict. Two other companies, the 10th and 11th, were scheduled for Korea but were deactivated in Japan. During the course of the Korean War, 100 Rangers were killed in action and 296 were wounded in action.
