When South Korea's national defense guard was founded, enlisted ranks were divided in to private and private first class. These terms have been used ever since. |

In 1962, enlisted ranks were divided into four, and those who were in upper rank of the enlisted were called corporal |
Sergeant |
 |
The term sergeant was used to signify the head of enlisted ranks |
Non-commissioned officer
In 1996, Non-commissioned officers' insignia was revised from the past insignia on which their insignia was marked on top of that of the enlisted soldiers causing it to look too big. So to arouse their pride and to make it look like the insignia of the officers, they added the Mugunghwa sign underneath their insignia.
