Following the 11 September terrorist attacks the Australian Government directed Defence to re-establish a JIRU . This was achieved by establishing a new Incident Response Regimental HQ to command the CBRR Squadron and the Emergency Response Squadron ( ERS ) , though this sub-unit was disbanded in 2006 . The IRU was redesignated to form the Incident Response Regiment in May 2002 . A specialist Scientific and Technical Support Organisation staffed by civilian and military scientists was also formed and attached to the IRR
