Re boots - as a rockape I was wearing DMS boots in 1966, and jealous of just about everyone else at Khormaksar who was wearing desert boots. DMS stood for directly moulded soles, and hadn't long replaced the old drill boots with nailed leather soles. Pretty sure the army were wearing the same.
For those in Singapore at the time, we had much more fun
MPN, I was posted to Singapore the following year and you are damn right! Certainly made up for lost time.
