Security Forces Squadrons are deployable tactical units, broadly comparable in size and structure to an infantry independent rifle company, capable of providing force protection for RAAF elements or other formations. 2AFDS comprises four Rifle Flights and a Support Flight; each Rifle Flight consists of four 10-man Sections and a Headquarters element of one GRDEFO, a SGT and a signaller. Support Flight contains communications, signals, field engineering and reconnaissance elements (including snipers) and is commanded by a GRDEFO and an ADG Flight Sergeant. 1AFDS is an integrated unit of permanent and reserve members; while it is headquartered at RAAF Base Edinburgh, South Australia, it has reserve Rifle Flights located in New South Wales, South Australia, Tasmania, Victoria and Western Australia. In recent history 1AFDS has relocated to Amberley and has gained more permanent members with 3 rifle flights and is working closely with 2AFDS.
