History


Formation

Formed in March 1901, following federation, the Australian Army initially consisted of the six, disbanded and separate, colonial military forces' land components. Due to the Army being continuation of the colonial armies, it became immediately embroiled in conflict as contingents had been committed to fight for the
United Kingdom of Great Britain and Ireland The United Kingdom of Great Britain and Ireland was the union of the Kingdom of Great Britain and the Kingdom of Ireland into one sovereign state, established by the Acts of Union 1800, Acts of Union in 1801. It continued in this form until ...

Interbellum

Repatriation efforts were implemented between the armistice and the end of 1919, which occurred after the disbandment of the Australian Imperial Force. In 1921, CMF units were renumbered to that of the AIF, to perpetuate the honours and numerical identities of the units involved in WW1. During this period there was a complacency towards matters of defence, due to the devastating effects of the previous war on the Australian psyche. Following the election of Prime Minister

Colours, standards and guidons

Infantry, and some other combat units of the Australian Army carry flags called the King's Colour and the Regimental Colour, known as "the Colours". Armoured units carry Standards and Guidons – flags smaller than Colours and traditionally carried by Cavalry, Lancer, Light Horse and Mounted Infantry units. The 1st Armoured Regiment is the only unit in the Australian Army to carry a Standard, in the tradition of heavy armoured units. Artillery units' guns are considered to be their Colours, and on parade are provided with the same respect. Non-combat units (combat service support corps) do not have Colours, as Colours are battle flags and so are only available to combat units. As a substitute, many have Standards or Banners. Units awarded

''Australian Army Journal''

Since June 1948, the Australian Army has published its own journal titled the ''Australian Army Journal''. The journal's first editor was Colonel Eustace Keogh, and initially, it was intended to assume the role that the ''Army Training Memoranda'' had filled during the Second World War, although its focus, purpose, and format has shifted over time. Covering a broad range of topics including essays, book reviews and editorials, with submissions from serving members as well as professional authors, the journal's stated goal is to provide "...the primary forum for Army's professional discourse... nd.. debate within the Australian Army... nd improve the.. intellectual rigor of that debate by adhering to a strict and demanding standard of quality". In 1976, the journal was placed on hiatus as the ''Defence Force Journal'' began publication; however, publishing of the ''Australian Army Journal'' began again in 1999 and since then the journal has been published largely on a quarterly basis, with only minimal interruptions.
