Are there any other anomalies that personnel are aware of where UK troops are not recognised v other Commonwealth troops?
I'm sure
TTN will know the complete answer, but ISTR that the "Vietnam" clasp to GSM 1962 was only awarded to Aussies and Kiwis.
Assuming - like most GSM clasps - its qualification was "geographical", then there must have been a small number of Brits - Embassy staff? - who theoretically qualified.
Over to you
