Finally, in January 1944, the 2nd Armoured Brigade was disbanded, having never seen active service overseas. Many of its constituent units – the 13th Armoured Regiment, 12th Armoured Car Regiment and 21st/22nd Field Regiment – were also disbanded at this time, while others such as the 2/6th Cavalry Regiment and 2/4th Armoured Regiments, both 2nd AIF units, were transferred for further service with the 6th Division and 4th Armoured Brigade, seeing action on Bougainville and around Aitape–Wewak in 1944–1945. The previously assigned 2/9th Armoured Regiment also saw action after its transfer from the 2nd Armoured Brigade, taking part in the fighting on Tarakan and Labuan in 1945. The 20th Motor Regiment also subsequently served with the 11th Brigade, forming part of Merauke Force, undertaking defensive duties in a dismounted role in Dutch New Guinea.
