Operations Support Group
Operations Support Group (OSG) are specialist police within the New South Wales Police Force. They are trained in public order (riot) response; weaponless control (hand to hand); violent prisoner cell extractions; high-value asset protection; navigation and terrain search; bomb searching and chemical, biological and radiation (CBR) response l Often mistakenly referred to as the ″operational support group″ by the media and even sections of the NSW Police Force, the OSG form part〔http://www.police.nsw.gov.au/about_us/structure/operations_command/major_events_and_incidents_group/mounted_unit/duties〕 of the state's public order and high urgency response in troubled areas such as Kings Cross, Redfern and Auburn in the CBD, extending statewide to regions like Bourke, Grafton and Moree. OSG officers perform the role in a 'part-time' capacity in addition to their primary duty (whether it be general duties, highway patrol etc.). The full-time unit is known as the Public Order and Riot Squad.
==History==
In 1981 the NSW Police Force created the Tactical Response Group (TRG) whose primary tasks included riot control/response, high risk search warrants, searches for missing person, crowd control and bomb search. The TRG's tactical duties were shared between another specialist unit of the time known as Special Weapons and Operations Section(SWOS) with both units fulfilling the role of being the state's official SWAT team. During the Bathurst Riots 1985,〔http://www.therealmountpanorama.com/bathursthistory/riots.php〕 the TRG showed their mettle against overwhelming odds; however, more public-order-specific police were desperately needed. In 1991 both the TRG and SWOS were made defunct and replaced with the Tactical Operations Unit (TOU)whose primary is specialist counter-terrorist and hostage-rescue functions and not riot control/response. The removal of riot control/response left a shortfall in NSW Polices ability to respond/deal with public order offences.
As such, a small contingent of officers trained in crowd control, then known as the Patrol Support Group (PSG) was formed in various Districts. This name was soon to change from Patrol Support Group to Operations Support Group. The OSG were formed in the now Central Metropolitan Region in the early 1990s, but were limited in both numbers and resources. As a new unit, the OSG's capabilities were unclear to police commanders themselves, and they worked mainly in limited numbers in the Sydney CBD at peaceful rallies and protests.
With the 2006 creation of the Public Order and Riot Squad, OSG units are officially known now as the Public Order Operations Support Group.
