Operation Claymore (3/4 March 1941) was the 1st Lofoten Islands raid off the Norwegian coast just north of the Arctic Circle. It achieved a good measure of destruction of German ships and fish factory oil and it gave free passage to the UK to over 300 Norwegian volunteers and a few Germans and Quislings. It was, however, most notable for giving a great boost to flagging morale within the ranks of the Commandos and later the country as news of the raid was made public.

Operation Anklet, (26-27/12/41) the second Lofoten Islands raid, was a diversion in support of a larger action at Vaagso further south on the Norwegian coast. There was no opposition to the landing, but a near miss from a German bomber convinced the planners that in future operations of this kind, air cover would be provided as a matter of routine.

Operation Archery (27/12/41), the raid on Vaagso and Maaloy , broke new ground with the provision of air cover as an integral part of the raid in the initial planning process. The planners had learned from the 2nd Lofoten raid that the lack of air cover could put similar missions in jeopardy.

Operation Musketoon (15-22/9/42) was a daring raid on an electricity generating station at Glomfjord in German occupied Norway not far away from the Arctic Circle - a station that provided the electricity for a nearby aluminium plant. The unit chosen for the mission comprised 2 Officers, 8 Commandos from No 2 Commando and 2 Norwegian corporals working for the Special Operations Executive (SOE). They were transported by submarine to a remote Fjord, completed a difficult high level overland route to approach their target from the rear and successfully destroyed their target. They paid a high price but such was the damage that the plant was inoperable for the duration of the war.
