The departure of virtually all senior British officers following independence, and their replacement by Indian officers, meant many of the latter held acting ranks several ranks above their substantive ones. For instance, S. M. Shrinagesh, the ground-forces commander of Indian forces during the first Indo-Pak War of 1947–49 (and the future third COAS), was first an acting major-general and then an acting lieutenant-general during the conflict while holding the substantive rank of major, and only received a substantive promotion to lieutenant-colonel in August 1949. Gopal Gurunath Bewoor, the future ninth COAS, was an acting colonel at his promotion to substantive major from substantive captain in 1949, while future Lieutenant General K. P. Candeth was an acting brigadier (substantive captain) at the same time. In April 1948, the former Viceroy's Commissioned Officers (VCO) were re-designated Junior Commissioned Officers, while the former King's Commissioned Indian Officers (KCIO) and Indian Commissioned Officers (ICO), along with the former Indian Other Ranks (IOR), were respectively re-designated as Officers and Other Ranks.
