The Royal Australian Armoured Corps (RAAC) is a corps of the Australian Army which provides the Australian Defence Force's armour capability.

The Royal Regiment of Australian Artillery, normally referred to as the Royal Australian Artillery (RAA), is a Regiment of the Australian Army descended from the original colonial artillery units prior to Australia's federation. Australia's first guns were landed from HMS Sirius and a small earthen redoubt built, near the present-day Macquarie Place, to command the approaches to Sydney Cove. The deployment of these guns represents the origins of artillery in Australia. These and subsequent defences, as well as field guns, were operated by marines and the soldiers of infantry regiments stationed in Australia. The first Royal Artillery unit arrived in Australia in 1856 and began a succession of gunner units which ended with the withdrawal of the imperial forces in 1870 resulting in the raising of the Victorian Artillery Corps in Melbourne in 1870 and the New South Wales Artillery in Sydney in 1871. The First World War saw the raising of 60 field, 20 howitzer, and two siege batteries along with the heavy and medium trench mortar batteries. Until 19 September 1962 the Australian Artillery was referred to as the 'Royal Australian Artillery', however, on this date HM Queen Elizabeth II granted the RAA the title of 'The Royal Regiment of Australian Artillery'. The Regiment today consists of Regular and Reserve units.
