Australia in the Korean War
No. 77 Squadron converted to P-51D Mustang fighters before arriving in Japan in February 1946 to participate in the British Commonwealth Occupation Force. Occupation duties proved uneventful, and No. 77 Squadron was preparing to leave Japan for Australia when the Korean War broke out in June 1950. 77 Sqn was immediately dispatched to Korea, where they became the first UN air unit to enter the war, primarily in ground support, combat air patrol, and escort missions.

The series' second volume, entitled "Combat Operations", was published in 1985. The book's account of the Australian Army, Royal Australian Navy and Royal Australian Air Force's operations in Korea is highly detailed. Because the three services rarely operated together O'Neill was able to treat their operations separately when writing the book.
