On 22 February 1973, the Dutch government officially created a specialist counter-terrorism unit in response to the
Munich massacre, when 11 Israeli athletes were murdered by Palestine pro-
Fatah militants. The government felt the urge of protecting the nation against such incidents in the future, and so members of the Dutch Marine Corps were selected for this special unit. Marines were chosen because, at that time, they were particularly notorious: Dutch marines are hardened, highly trained, professional soldiers. On July 1, 2006, a new government organ,
Dienst Speciale Interventies (DSI) was founded. This is a joint operations centre for counter-terrorism actions in the
Netherlands. Members of the UIM and special police units work together, and form a
Unit Interventie, which is a joint task force of Defence and police personnel. As part of the reorganization, the BBE changed its name in 2006 to the UIM. In 2009, the UIM changed its name once again to M-Squadron. The unit was reorganized into the Maritime Special Operations Force since January 1, 2009. ==Role==
