Al R - You are right about WW1 wound stripes, but they also had them in the British army in WW2 (not sure about the other services). They were a short gold stripe worn vertically on the lower sleeve. I'm not sure when their use was discontinued, but I can't see why something of the kind couldn't be re-introduced now. As well as the American Purple Heart already referred to, the Germans had wound badges in 3 classes, depending on the number of wounds, and the French had medals for the wounded, so we would not be exceptional. I think a symbol on the medal ribbon is a better idea than a stripe on the uniform simply because that remains after the individual has left the service, and they could be awarded retrospectively.
Nice to see your medal Sasless - interesting to see it is named. Examples I have seen have been unnamed as far as I recall - did you have that done privately?
