Initially the new regiment was equipped with Churchill tanks, although this was only a temporary measure until Centurion tanks could be acquired. However, due to the perceived unsuitability of the Churchill and the late arrival of the new platform, the regiment was not deployed as part of Australia's commitment to the Korean War, although a number of officers served on exchange with British and US formations and the unit provided machine-gunners and signalers to Australian infantry battalions as reinforcements. The first Centurions finally began arriving in June 1952, with the regiment receiving 39 tanks. With the numbers of regular personnel steadily growing, it was possible to raise Regimental Headquarters, Headquarters Squadron and B Squadron, and the regiment was fully raised by 8 September 1952 under the command of Lieutenant Colonel Stuart Graham.
