of Japan and the eventual peace settlement. After some delays the 65th, 66th and 67th Battalions arrived in Japan's Hiroshima Prefecture in February 1946. Subsequent employment "involved activities designed to reinforce upon the Japanese the lesson of their defeat", in addition to guard duty, patrolling and training. In December 1948 the Australian component of the BCOF was reduced from a brigade to one understrength battalion, with the 1st and 2nd Battalions returning to Australia, while the 3rd Battalion remained in Japan. On return to Australia the 34th Brigade became the 1st Brigade. The 1st Battalion was subsequently based in Ingleburn, New South Wales, and the 2nd Battalion at Puckapunyal, Victoria. Both units were significantly understrength as many men discharged on returning to Australia, while others elected to remain in Japan with the 3rd Battalion. Alan Morrison, a former member of the regiment, later recalled that for the two battalions that returned to Australia "...the first eighteen months of the regiment's existence were harrowing times". Many men discharged due to frustration and discontent, while the battalions were not strong enough to undertake meaningful training activities and their barracks were in a state of disrepair. Yet from this experience came the core "...of dedicated soldiers destined to be the non-commissioned officers of the regiment in the Korean War and the outstanding warrant officers and sergeants of the battalions that served in Malaya and in the early part of the Vietnam campaign". The regiment has provided units and individuals for virtually all Australian Army deployments and operations since its formation. The first period of sustained operational service began with the regiment's first deployment in Korea in 1950 and continued until the withdrawal of combat units from Vietnam in 1972. These 22 years were arguably the most significant for the regiment with between one and three battalions involved in combat operations in South-East Asia at any one time. A second lengthy period of operational service commenced with the intervention in East Timor in 1999, which became the first of many commitments for the regiment that have continued to the present day. Approximately 85,000 personnel have served in the RAR during this time, with casualties sustained by the regiment on operations including 693 killed and over 3,000 wounded. Korean War, 1950–1953 The Korean War was the first major test of the regiment. Following preparations in Japan, 3 RAR arrived in Pusan on 28 September 1950
