When I was first about to join the SH Force (SRT in them days), I was told "the most important thing you can learn is how, as a flying officer, to tell a major to f
k off"..... the answer of course is "not in those exact words".
Proved true for years and years, when I was a few pay grades higher than a flying officer, and could tell a general to f
k off ...... but not in those exact words.......
