History The British IV Corps, under the command of Lieutenant-General Noel Irwin, was deployed from the Middle East in January 1942, for the defense of Assam from the advancing Japanese during the Second World War. Following the end of the war, the corps was demobilised in November 1945.

The corps was re-raised by Lieutenant General Brij Mohan Kaul at Tezpur, Assam on 4 October 1962, close to the Sino-Indian War.Orbat.com, Indian Army Corps 2003, accessed July 2010 Over the years, it has played a role in both conventional and counter-insurgency operations in the eastern theatre, especially during the 1971 war in Bangladesh.

During the Indo-Pakistani War of 1971, the Gajraj Corps made the famous advance to Dhaka during the liberation of Bangladesh and also participated in the Meghna Heli Bridge Operations. Lieutenant General Sagat Singh, PVSM had innovatively employed Mi-4 helicopters to cross Meghna River, which was considered impassable and his Corps relentlessly attacked and defeated the Pakistani forces. The innovative use of helicopters has remained unparalleled. The Corps had proved its mettle and very proficiently carried out its task in the most complex sector in terms of distances from the logistic bases.

The corps has been active in counter-insurgency roles as part of Operation Bajrang (from November 1990), Operation Rhino I (from September 1991) and Operation Rhino II (from April 1992).

The monorail, with a capacity of over in a single run, has been operational at an altitude of since November 2025. The system can operate in day-night as well as adverse weather conditions to transport logistics (including rations, ammunition, fuel and engineering stores) and casualty evacuation.
