7th Combat Service Support Battalion ( Australia ) The 7th Combat Service Support Battalion ( 7 CSSB ) is an Australian Army administration and logistics battalion which provides transport , supply , catering and maintenance support services to units of the 7th Brigade . The battalion is made up of both Regular and Reserve personnel and has recently been involved in deployments to Timor Leste , Iraq and Afghanistan . History . Formation . 7 CSSB was formed on 1 July 1997 when the Kelvin Grove - based 7th Brigade Administrative Support Battalion ( 7 BASB ) , a Reserve unit that had been formed in 1994 , was amalgamated with the Enoggera - based 6th Brigade Administrative Support Battalion ( 6 BASB ) , an integrated Regular and Reserve unit that had been formed in 1993 . This came about as a result of the decision to disband the 6th Brigade , which resulted in 7th Brigade becoming an integrated Regular and Reserve unit . By 1999 , the battalion had an authorised strength of 647 personnel , of which 55 per cent were Reservists . When the 7th Brigade was reorganised in 2007 as a primarily Regular motorised brigade , although major Reserve elements were transferred to the 11th Brigade , 7 CSSB continued to maintain a small Reserve element . Operational experience . 7 CSSB regularly supports operational deployments in all ADF theatres with individual and small group reinforcements . In late 2003 , 7 CSSB supported the 6th Battalion , Royal Australian Regiment ( 6 RAR ) - based " Australian Battalion IX " ( AUSBAT 9 ) deployment to Timor Leste as part of Operation Citadel . They returned to Brisbane in mid - June 2004 . In 2005 , elements of the battalion deployed to Iraq as part of SECDET , which was during Operation Catalyst . In 2007 – 08 , the 7th Brigade provided the main force elements for the fourth rotation of the Australian Overwatch Battle Group ( West ) ( OBG ( W ) - 4 ) . Elements of 7 CSSB deployed in support OBG ( W ) - 4 , whilst the unit also contributed personnel to the Australian Army Training Team ( AATT ) . In 2010 , elements of the battalion were deployed to Afghanistan as part of Operation Slipper . While the majority of the battalion ' s force was part of the Force Support Unit based in Tarin Kowt , Kandahar and Al Minhad Air Base , elements also deployed in support of the 6 RAR - based 1st Mentoring Task Force ( MTF - 1 ) combined arms battle group that was deployed to Uruzgan province to conduct counter - insurgency operations . Current role and structure . Based primarily at Gallipoli Barracks , Enoggera , in the northern suburbs of Brisbane , the battalion is staffed by both Regular and Reserve personnel from various service support corps of the Army . In 2012 , the battalion underwent a significant restructure which saw both the detachment of Health Company to the Joint Health Command and 17th CSS Brigade , and the re - establishment of " corps based " sub units . As a result , 7 CSSB now consists of the 5th Transport Squadron , 106 Field Workshop Squadron , 1st Field Catering Company , 6 Field Supply Company and Battalion HQ . This restructure is significant as it re - establishes the links with the unit ' s predecessors in 6 BASB and previously independent sub units . The unit is currently under the command of Lieutenant Colonel Jeremy King and consists of a number of company - sized sub units , which can be detached to provide support at various levels . Some Reserve elements of the battalion are based in Toowoomba .
