The Corps of Army Air Defence (abbreviated AAD) is an active corps of the Indian Army, and a major combat formation tasked with the air defences of the country from foreign threats. The Corps is responsible for the protection of Indian air space from enemy aircraft and missiles, especially those below 5,000 feet.
The history of the AAD dates back to 1939, during the times of the British Raj in India. The corps actively took part in the Second World War, fighting on behalf of the British Empire. Post-independence, the corps has participated in all the wars involving India, starting with the 1947 Indo-Pakistani War, up to the 1999 Kargil conflict. The corps enjoyed autonomous status from 1994, after the bifurcation of the Corps of Air Defence Artillery from the Army's artillery regiment. A separate training school, the Army Air Defence College (AADC), was established to train its personnel.
