RAR on a system of unit rotation. During this changeover a parade was held to mark the first occasion that all battalions of the regiment had been on parade together. 1 RAR served a year in Korea, 2 RAR for four months before the armistice, while 3 RAR served throughout the war, earning itself the nickname of "Old Faithful". The last major action of the war for the regiment was the Battle of the Samichon River fought by 2 RAR over 24–26 July 1953, repulsing a number of major Chinese assaults just hours before the Armistice Agreement was signed. Following the armistice both sides withdrew and a demilitarised zone was created. The period that followed proved uneventful, yet the UN forces were required to maintain combat readiness and the ability to react quickly in case the North Koreans violated the ceasefire. In April 1954, 2 RAR returned to Australia and was replaced by 1 RAR which remained in South Korea until March 1956. 3 RAR finally returned to Australia in September 1954 after four years of continuous service in Korea and five years before that in Japan. Total Army casualties in Korea included 293 killed, 1,210 wounded and 23 captured, the majority being infantrymen of the Royal Australian Regiment. The fighting in Korea provided the regiment with valuable combat experience, establishing a foundation for its further development and marking the emergence of the Australian Regular Army. The Korean War remains the only large-scale, conventional war that the regiment has fought. During this time the Army developed the capability to maintain two battalions on major operations at the same time. Malaya and Borneo, 1955–1966 In April 1955 the Australian government had committed army, navy and air force elements to the Far East Strategic Reserve to assist in the defence of Malaya from internal and external security threats. While British Commonwealth forces had been operating against the communist terrorists since 1948, the battalions of the regiment came relatively late to the Malayan Emergency, and when 2 RAR arrived in theatre in October 1955 to join the 28th British Commonwealth Brigade, the war had been running for over seven years. 2 RAR was replaced by 3 RAR in 1957, which was in turn replaced by 1 RAR in 1959. During the Emergency the three battalions were involved in 45 contacts, killing 17 guerrillas for the loss of seven men killed in action. According
