No. 2 Commando and No. 9 Commando faced with the same problem had adopted the Tam o' Shanter, but, as a traditional Scottish headdress, this was not considered suitable for what was a British unit. After some discussion it was agreed that if No. 1 Commando was to adopt a uniformed headdress then the beret, which had been worn by the Tank Regiment since the First World War (and had recently been adopted by the Parachute Regiment), would meet the requirements: it had no British regional affinity, it was difficult to wear improperly, and it could be easily stowed away without damage (when for example tin hats were in use).
