My recent purchase... Like others, I won't have a blood group or call sign patch.. but ones that I don't see everyone and their neighbour wearing!
I came back from Kurdistan (Syria/Iraq) last month and managed to find along the way two flag patches that I'm proud to be wearing though... (Can see them in my signature!)
the one in my profile pic is the site patch and on the front I have a subdued union jack with a poppy in the middle. I have a subdued st Andrews cross on my right arm but I am considering sewing a TRF onto the original MTP patch instead, especially now that I have finally bought a stable belt to use in skirmishing
