Royal Australian Army Ordnance Corps The Royal Australian Army Ordnance Corps ( RAAOC ) is the Corps within the Australian Army concerned with supply and administration , as well as the demolition and disposal of explosives and salvage of battle - damaged equipment . The Corps contains clerks , operator supplies ( including q - store staff , warehouse staff and food technicians ) , petroleum operators , parachute riggers and ammunition technicians . Members of the Corps are nicknamed Roaches . Unlike other Corps within the Australian Army , there are no longer any RAAOC specific units , instead RAAOC sub - units sit within mixed units such as Combat Service Support Battalions ( CSSBs ) or Force Support Battalions ( FSBs ) . RAAOC is also responsible for clerks and quartermaster store staff in all Australian Army Units . The motto of the Royal Australian Army Ordnance Corps is ' sua tela tonanti ' ( commonly translated to ' to the warrior his arms ' ) , taken from the mother corps , RAOC . History . The Corps traces its history back to federation where General Edward Hutton started the Australian Army Ordnance Corps . The Corps gained its Royal prefix for its work during the Second World War . The RAAOC motto translates from Latin to ' To the warrior his arms , to the thunderer his thunder bolts ' . The RAAOC badge originates from the Board of Ordnance in the United Kingdom . On 31 May 1973 the Royal Australian Army Service Corps ceased to exist and the responsibilities of road , transport , air dispatch and postal functions were handed over to the Royal Australian Corps of Transport ( RACT ) who were formed on 1 June 1973 . The responsibilities of provision of foodstuffs and POL ( petrol oil lubricants ) was handed over to the Royal Australian Army Ordnance Corps ( RAAOC ) . Structure . Members of the ordnance corps will be found serving in most Army units and headquarters . The primary Regular Army units manned by RAAOC soldiers are : Force - level units . However , many Regular Army RAAOC trades are posted to units of all Regular and Reserve units throughout the Australian Defence Force as clerks , storemen ( - persons ) and other administrative and support roles . RAAOC BOSCs . The Army Reserve element of the Corps used to also consist primarily of Supply Companies , with 4 , 5 , 8 , 11 , 13 Supply Company of each Combat Service Support Battalion ( CSSB ) of the respective numbered Brigades in each state . These supply companies have been replaced by Brigade Operations Support Companies ( BOSCs ) in each Reserve Brigade . This implementation has centralised supply support to Army Reserve units , and as such , has been witness to a change of trade for Army Reserve members from warehousing ( as in the old reserve Supply Companies ) to Q - store streams . CSSB still exist in the Reserve Brigade , the BOSC replaces Admin Company , Supply Company and Catering Company . The BOSC is Controlled by the CO of the CSSB of that Brigade . Some positions will be replaced by APS , other positions won ' t be replaced once ARA staff are posted out in the future . The old Supply Companies will make a limited return , but the APS civies will run them as Brigade Operational Support Company ( BOSC ) . The CSSB will have their own Q store manned by ARes members .
