These three men were Lieutenant Colonel Malcolm Murray who commanded the 2nd Ranger Company of the Swedish Volunteer Corps at Hanko in Finland in 1941, Gösta Benckert with war experience from both Finland and Norway, and the paratrooper Erik G:son Lewenhaupt, with experience of fighting in Normandy, among other places.

[3] The next step was the training of four Swedish officers at the Royal Marines and the French amphibious school in North Africa.

In Sweden, the history of combat divers is closely linked to that of both coastal rangers and the Röjdykare (Swedish Navy EOD).

[4] In 1955, the Chief of the Navy, Vice Admiral Stig H:son Ericson received the Supreme Commander, General Nils Swedlund's permission for experimental training of coastal rangers.

Since the year 2000, however, the unit has been reorganized into its current organisation and is now composed of full-time professional personnel with emphasis on reconnaissance patrols behind enemy lines but still retain the capability to conduct direct action missions.

The Coastal Ranger are trained at the 1st Marine Regiment which is headquartered at Berga Naval Base located in east central Sweden.

He is also trained in encryption and laser guidance as he is the one that is in charge for guiding airstrikes and artillery to located enemy targets.

The extra and heavy radio equipment requires the specialist to have excellent physical stamina, although, the load is normally rotated around the team.

The purpose of the demolition experts is to give the teams the ability to conduct ambushes using mines, and to perform sabotage with explosives.

To be accepted to the very demanding basic Coastal Ranger course (roughly 12 months long), the candidate must already be serving member of the Armed Forces for at least one year, or have completed conscription.

If the candidate is deemed fit for service with the unit then he may attend the Coastal Ranger basic course and then move on to specialize to a specific role within a patrol.

The Coastal Rangers have served on several rotations in Afghanistan, predominantly as Mobile Observation Teams, or as mentors embedded with the Afghan National Army.

In 2015, personnel from the unit deployed to Mali as a part of the SWE ISR TF with the Army's 32nd Intelligence Battalion (ISTAR).

Until 1994, the green beret was exclusive to the Coastal Rangers and was awarded for successfully completing Operation Neptune along with the trident cap badge.

But as the rest of the amphibious battalion too were allowed to wear the beret (without trident), the Rangers exchanged the cap badge for the uniform patch as their unit insignia.
