On 1 March 1968 the Australian and New Zealand governments agreed to merge the New Zealand rifle companies into one Australian battalion which resulted in both New Zealand companies integrating with A, B, and C Companies of 2 RAR to become 2 RAR/NZ (ANZAC). With a total of five rifle companies it was stronger than the standard Australian battalion which only had four. New Victor and Whisky companies from RNZIR were again attached to subsequent 4 RAR and 6 RAR rotations during later tours. The ANZAC battalions were commanded by an Australian officer, with a New Zealand officer appointed as deputy commander. All of the New Zealanders were regular soldiers. In late 1968 a New Zealand Special Air Service troop was also attached to the Australian SAS Squadron. New Zealand strength peaked at 552 troops in 1969. At its height 1 ATF numbered over 8,000 men, including three infantry battalions, armour, artillery, engineers, logistics and aviation units in support.
