Later in 1940, the British Commandos were formed following Winston Churchill's call for "specially trained troops of the hunter class, who can develop a reign of terror down the enemy coast." By 1941, the Commandos were carrying out raids on the German-occupied Norwegian coast in Operation Claymore and Operation Archery and in 1942, they formed the assault troops for the St Nazaire Raid. They eventually formed 30 battalion-sized commando units (including 8 Royal Marines units), some of which were organised within four brigades; 1st, 2nd, 3rd, and 4th Commando brigades.
