““After World War Two, the Australian army had been re-organised into its peace-time army status. The army was primarily three battalions which together with supporting units, formed a regiment and the battalions making up the regiment were identified by both their number and the title of the regiment. This meant that the First Battalion Royal Australian Regiment was identified by the initials of 1RAR. The two other battalions were identified as 2RAR or 3RAR. At the height of Australia’s commitment to the Vietnam War (Second Indochina War) Australia had a total of nine battalions which were later called the First Division.””
