Re Post No 6, I received no language training prior to my exchange tour in Australia, where I flew C130 A Model Hercules in the 1960s, so instead was forced to spend more than a few very pleasant hours in the Mess bar becoming acquainted with the local lingo!
I get 'refresher' training on ANZAC Day each year where I join the annual parade before the Cenotaph and afterwards in Westminster Abbey, remembering my mates of yesteryear and all the good times we had supporting the Australian Armed Forces in and around the Commonwealth.
