World War I The 1st Field Regiment was formed in 1914 following the outbreak of
World War I, designated as the "1st Field Artillery Brigade". The brigade saw action on the
Gallipoli Peninsula in 1915, supporting the British
29th Division around
Cape Helles from early May, and then the Australian
2nd Division around
Anzac Cove from October until the force was withdrawn back to Egypt. From mid-1916, the brigade supported the
1st Division on the
Western Front until the end of the war in November 1918. During this time, the regiment consisted of the following: the
1st Field Artillery Battery, 2nd Field Artillery Battery, 3rd Field Artillery Battery, 101st Field Artillery (Howitzer) Battery and the 1st Brigade Ammunition Column. On cessation of hostilities in 1918, the 1st Australian Field Artillery Brigade returned to Australia where it was disbanded in 1919.
World War II In the interwar years, the 1st Field Regiment was raised again as a
Militia formation. Later, during World War II, this regiment served within Australia. In addition to this regiment, the 2/1st Field Regiment was raised as part of the all volunteer
Second Australian Imperial Force. Under the Land 17 project in 2011 1st Regiment received 8 M777A2 lightweight towed howitzers to replace its
L119 field guns and
M198 howitzers, and the Advanced Field Artillery Tactical Data System (AFATDS), which is a fully automated digital battle-management system. In early 2012 it took delivery of the Digital Terminal Control System for observation post batteries. The regiment is currently based at Barce Lines, Gallipoli Barracks, Enoggera. In 2018, members of the Regiment deployed to Iraq on
Operation Okra as a part of Task Group Taji VIII. ==Current formation==
