Australia
Within the Australian Army, combat service support is provided to combat elements at various levels: first line (organic to battalion or regimental level), second line (at brigade level), and third line (at formation or higher). Thus, for example an infantry unit such as the
5th Battalion, Royal Australian Regiment will include a logistics company which fills supply, transportation and maintenance functions, while a combat brigade, such as the
7th Brigade, will be supported by a combat service support battalion such as the
7th Combat Service Support Battalion. At formation level, a CSS brigade – the
17th Sustainment Brigade – will provide health, signals, catering, transport, and other service support requirements.
