Indian Air Force ranks and insignia

[2] In May 1949, Lord Mountbatten, the inaugural Governor-General of India and himself a naval officer, dispatched a note to Prime Minister Jawaharlal Nehru, titled Names and Insignia of Indian Armed Forces, containing a list of suggestions regarding the nomenclature of the armed forces that were to be enforced upon the dominion's conversion to a republic.

[2] In the note, Mountbatten proposed that the future IAF should retain its predecessor's nomenclature as much as possible - advocating the retention of the RIAF's ranks, insignia and uniforms.

[3] In September 1949, Nehru forwarded the proposals to the country's minister of defence, Baldev Singh, recommending Mountbatten's suggestions, which were consequently enforced upon India's emergence as a republic on 26 January 1950.

[5] The rank was awarded for the first, yet only time in January 2002 to then-retired Air Chief Marshal Arjan Singh DFC, who served as the IAF's third Chief of the Air Staff (CAS) between 1964 and 1969, for his exceptional leadership of the IAF during the 1965 Indo-Pakistan War.

[7] Initially, for the rank of Air Marshal, the collar tabs did not immediately distinguish between the positions of Vice Chief of the Air Staff (VCAS), Air Officer Commanding-in-Chief (AOC-in-C) and other three-star designated positions; however, later three-star collar tabs were embossed with a wreath design to solely indicate the positions of VCAS and AOC-in-C.[7] The rank of Master Warrant Officer was introduced in February 1950.
