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.
1st Brigade (Australia)
Following the end of hostilities in August 1945, the existing structures were disbanded throughout 1945 and into 1946 and the Interim Army was raised. As a part of this, the 34th Brigade was raised for occupation duties in Japan. In 1948, with the establishment of the reformation of the Regular Army and the raising of the Australian Regiment (later known as the Royal Australian Regiment), the 34th Brigade was renamed the 1st Brigade following its return to Australia. During the Korean War, individual elements of the brigade were detached for combat in Korea, although they were subsequently placed under the command of other formations.
