The Royal Australian Regiment (RAR) is the parent administrative regiment for regular infantry battalions of the Australian Army and is the senior infantry regiment of the Royal Australian Infantry Corps. It was originally formed in 1945 as a three battalion regiment made up of the 65th, 66th and 67th infantry battalions; however, since then its size has fluctuated as battalions have been raised, amalgamated or disbanded in accordance with the Australian government's strategic requirements. Currently, the regiment consists of six battalions and has fulfilled various roles including those of light, parachute, motorised, mechanised and armored infantry. Throughout its existence, units of the Royal Australian Regiment have deployed on operations in Japan, Korea, Malaya, Borneo, Vietnam, Somalia, Rwanda, Cambodia, East Timor, the Solomon Islands, Iraq and Afghanistan.
