In recent history [c 1970-75] there really was a 4 commando Tp.
they were a 5 man team stationed in Nee Soon Barracks Singapore
supporting 28 ANZUK Bde and RN/RAN Ships in the Far East.
Hard men one and all. Hope I'm not giving the walts any ideas
But if you scroll over the picture it gives you each person's name. Accordingly the bloke second from the left in the front row is called
'4 Commando at Kent and E Sussex Railway May 2005'.
Whether a walt or re-enactor that is serious dedication to the 'unit'
