The RE's, by the way, are an outstanding bunch of folk, who rarely, IMHO, ever get their due recognition. Their tea is the best ever!! And always available, no matter where or when!!
IIRC there's a quote in "Don't Cry for Me Sergeant Major" where a party of RM storm a hill in the Falklands only to find a Sapper comfortably ensconced offering them 'a wet'!!!
