Yes the Scottish Royal Fusiliers were in the Battle of Dunkirk and some won medals. See the links below.
Unfortunately, due to this present Governments commitment to the Armed Forces of the UK, The Royal Welsh Fusiliers no longer exist. On St Davids Day (March 1) 2006, The Royal Welsh Fusiliers were disbanded and amalgamated into The Royal Welsh.So your question really should read, 'Who is the current RSM of the Royal Welsh'.Up until November 9th 2009, the RSM was Warrant Officer Class 1 (Regimental Sergeant Major) Darren Chant, who was killed in Afganistan on that date. I have been unable to find out who was promoted to fill that post.
