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.
Northeast Anti-Japanese United Army
The army contained a large number of ethnic Koreans, both the Koreans from Manchuria, and Koreans from the Korean Peninsula. By 1918, there were virtually no organized armed revolts against Japanese colonisation on the Korean Peninsula and many Koreans chose Manchuria as a place to resist Japanese Imperialism. Two of the legendary "Eight Girls Jumping Into the River" were Korean Chinese. This was a squad of girl guerrillas, aged from 13 to 23; after a long firefight with overwhelming Japanese forces who mistook them for a much larger unit, they all jumped into the river, drowning themselves to avoid capture and torture.
