Peacekeeping
The Sri Lanka Army has taken part in two peacekeeping missions with United Nations over the course of its history. First assignment was in the Congo (ONUC) (1960–1963). Most recently, following the signing of a ceasefire agreement was signed between the government and the LTTE in 2002,
Sri Lankan forces were invited by the United Nations to be part of the UN peacekeeping force in Haiti.[16] The Sri Lanka Light Infantry was selected to be part of the peacekeeping operations, and training programs on counter revolutionary warfare were conducted for the troops in Kukuleganga. Following the successful completion of the training, a battalion under the command of Col. K.A.D.A. Karunasekara left for Haiti on October 22, 2004. In the process of the peacekeeping operations, 2 soldiers were killed in a raid in Petit-Goave.[17] After over 6 months of service, the first contingent of the peacekeeping force returned to Sri Lanka on May 17, 2005[16]. In December 2007, 7th rotation of the Sri Lankan contingent had been deployed with a force of 991 officers and other ranks, many of the those deployed have been awarded the United Nations Medal for their services.
