Did a search first before posting, but does not seem to have been discussed here before, so may be of interest to some of the members. The footage is presented in four parts with clips spanning several years from both training in Canada and later in the UK whilst preparing for Normandy. Of particular interest is identified SAR armour using red tactical signs in early 1944.
