 Unlike the former SWOS and TRG, the TOU is a completely full-time assignment with a strength of 75 officers and is not responsible for riot control or crowd control situations, which are handled by the Public Order and Riot Squad (PORS).The TOU is available to provide extraordinary assistance to operational police in high-risk incidents such as resolving siege and hostage situations, as well as armed offender situations across the State on a 24-hour basis.The TOU also conducts 'high risk' arrest operations of armed and dangerous offenders such as Ivan Milat, Malcolm Naden, or those involved in firearm incidents such as bikie related shootings.
