Indian Army I Corps, September 1965, Operation Nepal
v.1.2 April 14,  2002

Ravi Rikhye

This is an incomplete orbat and may be wrong in some respects because units were being shifted between formations all the time. I have relied primarily on Lt. Col. (Retired) Dr. Bhupinder Singh’s excellent doctoral thesis, 1965 War: The Role of Tanks in India-Pakistan War, published by BC Publishers, Patiala, India, 1982; and the unauthorized release of the official 1965 War, with thanks to Mr. P.V.S. Jagan for providing a copy. You are welcome to expand on, or correct this orbat. Please be sure to copy and paste this file and work directly within the file.
