The Indian Army is the land-based branch and largest component of the Indian Armed Forces. The President of India is the Supreme Commander of the Indian Army, and its professional head is the Chief of Army Staff (COAS). The Indian Army was established on 1 April 1895 alongside the long established presidency armies of the East India Company, which too were absorbed into it in 1903. Some princely states maintained their own armies which formed the Imperial Service Troops which, along with the Indian Army formed the land component of the Armed Forces of the Crown of India, responsible for the defence of the Indian Empire. The Imperial Service Troops were merged into the Indian Army after independence. The units and regiments of the Indian Army have diverse histories and have participated in several battles and campaigns around the world, earning many battle and theatre honours before and after Independence.

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. Unlike their British and Canadian equivalents, there are no regiments of horse artillery in the order of battle of the Royal Australian Artillery. 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 Queen Elizabeth II granted the RAA the title of 'The Royal Regiment of Australian Artillery'. The Regiment today consists of Regular and Reserve units.
