Just a question the Commando's, LRDG and the SAS in WWII were they one and the same or different training for the group one volunteered for as I have seen a pic of the LRDG with their S/F knives in view in a group with their vehicles. It is just a question as I would have thought the individual was trained across all environments making them more deployable to create chaos and take out specific targets no matter where.
