The Special Operations Engineer Regiment (SOER) can trace its history to a number of specialist
Royal Australian Engineers organisations. The Emergency Response Squadron was initially formed in 1999 from the existing Army Fire Service in response to the 1996 Blackhawk Helicopter disaster in the Townsville High Range training area. The Chemical, Biological and Radiological Response (CBRR) Squadron was formed in 1999 by expanding the existing Chemical Radiological Response Team. In 1999, the
Joint Incident Response Unit (JIRU) was established as part of the
Australian Defence Force's security arrangements for the 2000
Sydney Olympic Games. The JIRU incorporated the CBRR Squadron, an EOD Squadron and a Technical / High Risk Search Squadron. JIRU was part of
Joint Task Force Gold. When the JIRU was disbanded in March 2001 the CBRR Squadron was retained as an independent squadron. On 24 February 2012, the IRR was disbanded and re-raised as the SOER. The reason for this change was to provide a more accurate name for the regiment's current role. The primary role of the regiment is no longer to respond to crisis management, but rather to provide counter-Chemical, Biological, Radiological, Nuclear or Explosive (C-CBRNE) and Mobility and Survivability capabilities to Special Operations. Like that of the IRR, teams of SOER personnel are integrated into the Australian Army's
tactical assault groups to maintain Australia's Domestic Counter Terrorism capabilities, whilst still supporting Special Operations in Afghanistan. The regiment once included an aviation emergency response capability in of support Special Operations Command. However, this has since been transferred to the 16th Aviation Regiment. Elements of the IRR deployed on combat in Iraq and Afghanistan as part of
Operation Slipper in support of the Special Operations Task Force. Later, as the SOER, elements of the unit also deployed on combat operations in Afghanistan and partner capacity building operations in Iraq. The Special Operations Engineer Regiment is composed of A and B Squadrons and a Logistic Support Group, based at
Holsworthy Barracks, approximately south-west of
Sydney,
New South Wales. ==See also==
