During the Korean War, although deciding against sending combat forces, India sent its 60th Parachute Field Ambulance unit to aid the UN troops fighting against the North Korean invasion of South Korea, as part of the 1st Commonwealth Division. In the aftermath of the war, an Indian infantry brigade formed the Custodian Force of India, some of whose soldiers were also part of the Neutral Nations Repatriation Commission, which assisted in the exchange of prisoners of war and was headed by Lieutenant General K. S. Thimayya.
