Following the failed amphibious assault during the Yosu Rebellion, Admiral Son Won-il tasked Shin with creating a ground combat unit (陸戦隊) within the Navy.[2] he was assigned as one of the core members of ROK Marines and founded ROK Marine Corps on April 15, 1949.

He voluntarily relinquished the Corps' top position following the war, but remained in uniform until May 1961.
