What does Australian Army do?

The Australian Army is the land warfare branch of the Australian Defence Force (ADF), dedicated to defending Australia and its national interests through ground-based military operations, training, and readiness. It is one of three services in the ADF, alongside the Royal Australian Navy and Royal Australian Air Force, with a personnel strength contributing to a total of over 90,000. Tracing its origins to pre-Federation colonial forces, the Army has evolved into a modern military organization structured under the Department of Defence. It operates under a diarchy led by the Chief of the Defence Force and the Secretary of the Department of Defence. The Army is organized into three main elements: the 1st Division Headquarters, Forces Command, and Special Operations Command, with a focus on operational readiness and support for joint ADF missions. Key units include infantry battalions, armored and cavalry regiments, and various support corps, all adapting to technological advancements and tactical needs.
