(Hope this is the right place to post this?) I'm currently sorting through a bunch of my Dad's photos, taken whilst he was in India with the 25th Dragoons, 1945-47. I've come across several photos of these tanks - he was a driver/mechanic - and on the reverse of this one he's written "DD Shermans Madh Island, March 1947". I'm assuming he was part of the activity recorded on the newspaper clipping in the same envelope and though I know he drove a Sherman tank, I'm wondering what the DD means? Does it refer to the covering? I'd love to know more!
