# Army Ordnance Corps (India)

The Army Ordnance Corps (abbreviated as AOC) is an active corps of the Indian Army and a major formation responsible for providing material and logistical support to the Indian Army during war and peace.

## History
### Pre-independence

The history of ordnance in India dates back to the 15th century. The early ordnance stores in the Indian sub-continent were established by the British East India Company for their logistical requirements. Following the military expansion of the company, the needs of military troops increased which in turn required the support of an ordnance department. By accepting the report of then Commander-in-Chief of the Bengal Army, Lieutenant General Sir John Clavering, the Board of Ordnance was established on April 8, 1775. This is considered to be the first step towards the recognition of the Army Ordnance Corps (AOC). Initially the board was put under the control of the Bengal Presidency.
With the increasing influence of the British crown over the sub-continent, the number of British troops increased significantly. In 1874, a "Special Ordnance Commission" was appointed by the government to prepare a report on the establishment of a new ordnance system at the national level. The report which was submitted on 7 April 1875 recommended a centralized system and the establishment of ordnance factories in the country. A report by the Army in India Commission, which was constituted in May 1879 by Lord Lytton, recommended the establishment of a centralized all-India organisation, headed by a Director General of Ordnance. On 1 April 1884, the Ordnance Department of India came into existence. The Ordnance's three Presidencies of the British Raj were integrated into one. An Inspector General of Ordnance was appointed to each Presidency and was responsible to the Director General at the national level. Following the Partition of Bengal (1905), the Ordnance was split into two, each with an Inspector General. Several reorganizations took place during the tenure of Lord Kitchener as the Commander-in-Chief of India.
Overruling the report of the Esher Committee of 1919 recommended that a civilian member be in charge of civil business. A military officer was put in-charge of manufacture and production as Master General of Supply. Later in 1929, the office of Master of General of Supply was rechristened Master General of Ordnance.
With of start of the Second World War in September 1939, the AOC began a major expansion that continued to the end of the war in 1945. The number of installations rose from 10 to 77 in the span of six years. On 1 May 1943, the Indian Electrical and Mechanical Engineers (IEME) was separated from Indian Armed Ordnance Corps.

### Post-independence

After India became republic on 25 January 1950, the corps was rechristened as the Army Ordnance Corps dropping the prefix Indian.

## Role and function

The Army Ordnance Corps main responsibility is to provide material and logistics support to the Indian Army and, if required, to the Navy and Air Force during war and peace. The inventory Army Ordnance Corps is responsible ranges from clothing (e.g. coats, sleeping bags, gloves, goggles, etc.) to vehicles, equipment and munitions (e.g. bullets, artillery shells, missiles, etc.). The supply of fuel, fodder, and medicines are maintained by the Indian Army Service Corps, the Military Farms Service/Army Remount and Veterinary Corps and the Army Medical Corps respectively.

## Training academy

The Army Ordnance Corps centre in Secunderabad is the training academy of the corps. The AOC centre is responsible to impart training to the ordnance corps personnel. Apart from military training, the AOC personnel are also trained in different kinds of repair works, ancillary trades such as carpentry, tailoring, saddlery, driving etc.
