4th Regiment, Royal Regiment of Australian Artillery (4 Regt RAA), provides field artillery support and coordination of joint fires and effects to support known and potential operational commitments as part of 3rd Brigade.
4th Regiment is structured as follows:
- Operations Support Battery – provides the Brigade Joint Fires and Effects Coordination Centre to HQ 3rd Brigade and command and control of the regiment’s artillery fires
- 106th Battery – supports 2nd Cavalry Regiment
- 107th Battery – supports 1st Battalion, Royal Australian Regiment
- 109th Battery – supports 3rd Battalion, Royal Australian Regiment
- Combat Service Support Battery – provides combat service support to the regiment.
108th Battery, while physically located with 4th Regiment, is now a sub-unit of 2nd Battalion, Royal Australian Regiment (2 RAR), which is generating a combined-arms battle group capable of manoeuvring from the sea as the land component of the Australian Defence Force’s amphibious capability.
4th Regiment is equipped with the M777A2 lightweight howitzer and uses the Advanced Field Artillery Tactical Data System (AFATDS) for command and control of artillery fires and the Digital Terminal Control System (DTCS) for target acquisition and calls-for-fire.
The unit was originally raised as 4th Field Regiment at Wacol, on 4 May 1960, becoming the first major Australian Regular Army unit to be raised in Queensland. The unit moved to Chau Pha Lines, Lavarack Barracks, Townsville, in 1968. The unit was renamed 4th Regiment in January 2011.
As a complete unit, 4th Regiment has served two tours of duty in South Vietnam, as well as sending individual batteries to South Vietnam, Singapore, Malaya and Timor-Leste (East Timor). Members of 4th Regiment have also served in training, advisory and combat roles in Iraq and Afghanistan.
