Wasn't sure where to put this so Infantry will do. Mate of mine stopped at services on M4 today saw what he thought were Royal Marines but they had Army Commando on the shoulder tab. Had a chat with a couple of them who told him they were in fact Army Commando's and were a separate organisation from Royal. How long have these been around? My mate thought they may have just passed as some of them were walking as if they had just done a 30 miler.
