2/15th Field Regiment was an Australian artillery regiment formed during the Second World War as part of the Second Australian Imperial Force. Raised in 1940, it served in training centres and on operations in the Middle East and the Pacific before disbandment in 1946. The unit provided indirect fire support to infantry and armoured formations and participated in campaigns alongside formations such as the 7th Division (Australia), 9th Division (Australia), and Allied units including the British Eighth Army and the United States Army.

Formation and Early History

The regiment was raised in late 1940 under the auspices of the Second Australian Imperial Force at training depots including Royal Military College, Duntroon, North Head, New South Wales, and Kapooka. Initial cadre drew personnel from militia formations such as the Royal Australian Artillery and volunteers returning from the Spanish Civil War diaspora and pre-war service in the British Indian Army. Early commanders liaised with staff officers assigned from the Australian Army Staff College and attended tactical exercises with formations based at Puckapunyal and Bathurst, New South Wales. The formation period included coordination with ordnance and signals units like the Royal Australian Army Ordnance Corps and the Australian Corps of Signals.

Organization and Equipment

Structured as a three-battery regiment, the unit comprised the 1st, 2nd and 3rd Batteries organized on principles promulgated by the War Office and adapted by the Australian Army Staff. Batteries were equipped with British-pattern 25-pounder field guns supplied via Imperial Chemical Industries logistics arrangements and the Australian Commonwealth Line. Fire control adopted methods from the Royal Artillery doctrine, integrating observers from the Royal Australian Air Force and forward liaison officers attached to infantry brigades such as the 20th Brigade (Australia) and the 21st Brigade (Australia). Maintenance and transport depended on vehicles produced by General Motors Holden and spares shipped through ports including Sydney Harbour and Port Adelaide. Communications used radio sets produced by Amalgamated Wireless and encryption systems influenced by lessons from the Enigma machine breaches and Allied signals intelligence coordination.

Operational Service

After embarkation from Port Melbourne the regiment served in the Middle East theatre, supporting operations in the Syria-Lebanon campaign and later integrated into the Western Desert Campaign supporting actions around El Alamein. There it coordinated with formations including the 8th Division (Australia) and the New Zealand 2nd Division under the strategic direction of commanders like Thomas Blamey and with operational linkages to commanders of the British Eighth Army such as Bernard Montgomery. During redeployment to the Pacific following Japan's entry into the war, the regiment adapted to jungle warfare and operated in New Guinea campaigns including actions near Kokoda Track logistics hubs and in assaults supported by units of the United States Fifth Air Force and the Royal Navy. The regiment provided support during amphibious operations in conjunction with the Royal Australian Navy and Australian armoured units such as the 3rd Armoured Division (Australia), integrating with Allied planning at headquarters including South West Pacific Area command under Douglas MacArthur directives. Throughout campaigns the regiment coordinated counter-battery fire, interdiction and creeping barrages in combined-arms operations alongside infantry brigades and pioneer battalions.

Postwar Disbandment and Legacy

Following the Japanese surrender and the cessation of hostilities, the regiment participated in demobilisation at staging areas including Morotai and returned personnel through processing centres at Canberra and Melbourne. Demobilisation policies followed legislation like the Australian postwar repatriation arrangements and directives from the Department of the Army. The regiment was formally disbanded in 1946, with veterans transferring to the postwar Citizen Military Forces and influencing artillery doctrine in subsequent rearmament programs that involved the Australian Defence Force and the Department of Defence. Former members contributed to commemorative activities with organisations such as the Returned and Services League of Australia and local historical societies; unit war diaries and service records were deposited with institutions including the Australian War Memorial and the National Archives of Australia.

Battle Honours and Decorations

The regiment's personnel received campaign recognition for theatres including the North African Campaign, the Syria–Lebanon Campaign, and the New Guinea campaign. Individual awards to members included mentions in despatches and decorations from systems like the Military Medal (United Kingdom), the Distinguished Conduct Medal, and appointments within the Order of the British Empire for meritorious service. The regiment's contributions were recorded in official campaign histories authored by historians affiliated with the Australian War Memorial and academic studies published through institutions such as the Australian National University.
