The National Task Force ("Nationella insatsstyrkan") is a national counter terrorism/high-risk intervention unit under the command of the National Operations Department. It was originally formed in 1991 solely as a counter-terrorist task force in the wake of the assassination of Prime Minister Olof Palme, on the recommendations put forward by a 1988 Government inquiry. It has evolved into a national police resource deployed in extremely dangerous situations, e.g. high-risk interventions, search and surveillance operations, hostage situations, tactical negotiations and various kinds of underwater operations.
