Jaffna University Helidrop
The Jaffna University Helidrop was the first of the operations launched by the Indian Peace Keeping Forces (IPKF) aimed at disarming the Liberation Tigers of Tamil Eelam (LTTE) by force and capturing the city of Jaffna, Sri Lanka, in the opening stages of Operation Pawan during the Indian intervention in the Sri Lankan Civil War. Mounted on the midnight of 12 October 1987, the operation was planned as a fast heliborne assault involving Mi-8's of the No.109 Helicopter Unit, the 10th Para Commandos and a contingent of the 13th Sikh Light Infantry.
