The Royal Australia Regiment (RAR) is the parent administrative regiment for Australian infantry battalions. The Australian Regiment was formed in 1948 from amalgamation of three infantry battalions occupying post-war Japan. In 1949 it was given permission to use the Royal title. During the Korean War, the 3rd Battalion of RAR joined the 2nd Battalion of Princess Patricia's Canadian Light Infantry (PPCLI) in stopping the advance of the Chinese Army at KapYong. Both units were awarded the U.S. Presidential Unit Citation. As a result of this shared experience, RAR and PPCLI are allied regiments. RAR has also seen active or peacekeeping service in Malaya, Borneo, Vietnam, Somalia, Cambodia, Rwanda, East Timor, Solomon Islands, Iraq, and Afghanistan. As of 2017 it consisted of six battalions.
