Camp Coiner is a USFK installation located on the northern part of Yongsan Garrison located in Seoul, South Korea. It was named after 2nd Lieutenant Randall Coiner assigned to the 3rd Battalion, 31st Infantry Regiment of the 7th Infantry Division who was posthumously awarded the Silver Star for actions taken in 1953 during the Korean War near the village of Sokkagae. Prior to the US military taking control of the camp from the Imperial Japanese Army, Camp Coiner was used as a garrison for a horse drawn artillery unit.
