From Wikipedia, the free encyclopedia
Wonsa is the highest enlisted South Korean military rank, equivalent to a Sergeant Major in most other countries. The rank of Wonsa is derived from the supreme officer rank of Wonsu and wears as its insignia three chevrons with a star centered above. The rank of Wonsa is greatly respected in the South Korean military with many of its holders approaching between 25 to 30 years of military service. Those holding the rank of Wonsa are eligible to be promoted to Junwi, considered the only Warrant Officer rank of the South Korean armed forces.
