I had a hospital appointment today. The House Officer was wearing dark trousers (navy blue, possibly black) and had a light blue/grey short sleeved shirt on. The shirt had epulauts, although they were the same pale blue/grey colour of the shirt. My first thought was 'RAF Doctor' although my OH insists that he was a Royal Marine doctor (I did see a RM on his ID badge followed by a surname, although not sure if that was his initials or does it stand for Royal Marine?) To confuse matters, this is a hospital in a naval town, and I know they have lots of the Navy doctors working at this hospital.
Any ideas which forces this uniform would belong to (am now kicking myself that I didn't just ask!)
