Drew Try to find a copy of Spearheading D.Day by Jonathan Gawne ISBN 2 908 182 793 published 1998. Should be able to order through the Library Service. If I remember correctly the Skull and X bones are a fairly standard unofficial insignia of the Coast guard it was used in Vietnam Steve
Cheers Steve, After I posted this article on another forum sometime ago I read ATB's D-Day and it gives a detailed ref to it Regards
