In June 1952, Forrester accompanied Kendall to South Korea, continuing to serve as his aide until October 1952. Forrester was then given command of Company E, 2nd Battalion, 9th Infantry Regiment, 2nd Infantry Division. The company occupied outposts and conducted company combat raids against North Korean and Chinese forces in the area around Old Baldy and Pork Chop Hill. In March 1953, Forrester's company was attacked while in the middle of a unit night rotation of the outpost on Little Gibraltar. He rallied several platoons and led a night counterattack that after several hours of battle, recovered control of the outpost. Forrester's Korean tour ended in July 1953 when he was again selected by now Lieutenant General Kendall for aide duty in Japan. That lasted until December when Forrester departed to attend the Infantry Officer Advance Course (1954) at Fort Benning, Georgia, followed by assignment to the U.S. Army Military Academy at West Point as tactical officer.
