XI Corps (India)
The XI Corps of the Indian Army is based in Jalandhar and is a part of Western Command.

History
XI Corps was raised to take command of the formations in the Punjab in 1950 as India reorganised its post-1947 army to meet the new threat of Pakistan. It was raised on March 1, 1950 at Ambala under the command of Lieutenant General Kalwant Singh. The corps headquarters was relocated to Jalandhar in July 1951.

To reduce the load of XI Corps, X Corps was formed at Bathinda on 1 July 1979, taking over south Punjab and north Rajasthan.

Formation Sign
The Corps formation sign consists of the 'red-white-red background' depicting a corps of the Indian Army overlaid by a Vajra, the powerful thunderbolt weapon of Lord Indra, the symbol of sacrifice of the great sage Dadhichi, who voluntarily sacrificed his body to make the fiercest weapon from his thighbone.
