It gets to me too, that's what annoyed me with the W&P show, you get people walking round in all types of uniform, CS95 desert trousers with trainers, a SAS beret and a 40's BD jacket, if you're going to portray someone, portray them realistically. But the medals, having earned medals in a number of wars, I've lost friends, I find it disrespectful.
I remember once we we guarding an airshow and we ejected a gent for claiming he was a serving RAF pilot, wearing Flt Lt flying suit and wearing SD shoes and an airman SD cap!!
The uniform law, I never knew about that!!
