The raiding forces were mostly provided by the British Commandos but the two largest raids, Operation Gauntlet and Operation Jubilee, drew heavily on Canadian troops. The size of the raiding force depended on the objective. The smallest raid was two men from No. 6 Commando in Operation J V. The largest raid involved over 10,500 men in Operation Jubilee. Most of the raids were scheduled to only last overnight, but some, like Operation Gauntlet, were conducted over a number of days.
