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.Circa 1953 to 1960.
