4th Regiment, Royal Australian Artillery

The 4th Regiment, Royal Australian Artillery is an artillery unit of the Australian Army. Currently it provides direct-support to the 3rd Brigade and is based at Lavarack Barracks in Townsville, Queensland. The unit was raised in 1960 and is currently re-equipping with M777A2 lightweight towed howitzers. The unit deployed during Australia's commitment to the Vietnam War and has subsequently deployed to Singapore and East Timor.

History
The 4th Field Regiment was raised at Wacol on 3 May 1960, being the first major Regular Army unit to be raised in Queensland. The Regiment moved to Lavarack Barracks in 1968. As a complete unit, the Regiment served two tours of duty in South Vietnam, as well as sending individual batteries to South Vietnam, Singapore, Malaya and East Timor.

In January 2011 the Australian Regular Army field regiments were reorganised in preparation for re-equipment with new guns and battle management systems to each contain three observation post batteries, supported by a single gun battery equipped with 12 guns. As part of this reorganisation the regiments were renamed, with the word "field" removed from their title. Under the new structure each regiment is capable of providing a brigade-level Joint Fires and Effects Coordination Centre (JFEEC) and every observation post batter provieds a battle group JFECC as well as three combat team joint fires teams. Every gun battery now comprises three troops of 155 mm towed howitzers.

Under the Land 17 project in 2011 4th Regiment will receive 12 M777A2 lightweight towed howitzers to replace its L119 field guns, and the Advanced Field Artillery Tactical Data System (AFATDS), which is a fully automated digital battle-management system. In early 2012 it will take delivery of the Digital Terminal Control System for observation post batteries. The regiment is currently based at Chau Pha Lines, Lavarack Barracks in Townsville.
